DECEMBER, 2006


  NOTE FROM THE AUTHOR: Almost two years ago I began including links to

  track graphics prepared by John Diebolt of Tucson, Arizona, and archived

  on his tropical cyclone website.  A few months back John experienced a

  disk crash which resulted in a error.  He had to request assistance from

  the programmer who had written the map-generation software, but so far

  has not been able to get the problem solved.   As a convenience to users,

  I've also recently been including links to the individual tabular tracks,

  prepared by myself, which John had archived on his website.  Now, due to

  family concerns, John has not had time to place the tracks for recent

  cyclones on the website.  I have checked the websites listed at the end

  of the summaries and found that the entire November track file has been

  archived on two of them.  The links are:



  UPDATE TO ABOVE NOTE: John has now gotten his website up and running

  again.  The link is:


  The December track file may be found here as well.  Also, John has

  already created graphics for the January, 2007, cyclones.  The page

  has been redesigned and is very user-friendly now.  To view any item

  of interest, click on the green bar to the right.


  As time permits we hope to make track graphics available for cyclones

  during the latter half of 2006.


  (For general comments about the nature of these summaries, as well as

  information on how to download the tabular cyclone track files, see

  the Author's Note at the end of this summary.)




                            DECEMBER HIGHLIGHTS


   --> Yet another typhoon moves through Philippines

   --> Intense tropical cyclone forms in Southwest Indian Ocean

   --> Possible subtropical storm forms off coast of Brazil




                   !!!!!!!!!! EXTRA FEATURE !!!!!!!!!!



                      FOR THE NORTHERN HEMISPHERE



       Following is a tabular summary of all the tropical depressions,

    tropical storms, hurricanes, and typhoons which occurred in the

    Northern Hemisphere between 1 January and 31 December 2006, as

    reported in the Monthly Global Tropical Cyclone Summaries prepared

    by the author.


      (1) Number - this is the sequential cyclone number assigned by either

                   TPC/NHC, CPHC in Honolulu, or JTWC.  If neither of these

                   agencies issued any warnings, no number will be given.


      (2) Name - the name (if any) assigned by either TPC/NHC, CPHC, IMD,

                 or JMA (and PAGASA for Western North Pacific systems in

                 their area of warning responsibility).


      (3) Dates - range of dates for which tracking information for the

                  cyclone is available in the Global Tropical Cyclone

                  Tracks files prepared by the author.


      (4) Pressure - Lowest central pressure (either estimated or recorded)

                     during the lifetime of the cyclone.  For Atlantic and

                     Northeastern Pacific systems these will be the values

                     reported in operational advisories from TPC/NHC or

                     CPHC.  For Northwest Pacific systems the central

                     pressure estimates are taken from advisories issued by

                     the Japanese Meteorological Agency.  An asterisk (*)

                     following the pressure indicates the reading was an

                     actual measured pressure normally obtained by a drop-

                     sonde released during an aerial reconnaissance

                     flight.    Central pressure is given in millibars,

                     which is numerically equivalent to hectopascals.


      (5) MSW - maximum 1-minute average sustained windspeed in knots.

                For the Northwestern Pacific and North Indian Ocean

                basins, these will be the highest value assigned

                operationally by JTWC.  For the Atlantic and Northeastern

                Pacific basins, the MSW values are taken from the

                official tropical cyclone reports prepared by the

                TPC/NHC Hurricane Specialists and which are available

                on TPC/NHC's website: <> .


      (6) Basins - tropical cyclone basins where the cyclone tracked during

                   its life:


                   ATL - North Atlantic, Gulf of Mexico, Caribbean Sea

                   NEP - North Pacific east of Longitude 180

                   NWP - North Pacific west of Longitude 180

                         (including South China Sea)

                   NIO - Bay of Bengal and Arabian Sea


       For tropical systems in the NWP basin, two additional columns of

    information are given:


       (1) The tropical storm serial number assigned by the Japanese

           Meteorological Agency to tropical depressions which are deemed

           to have reached tropical storm intensity.  This does not always

           agree with JTWC's assessment.


       (2) An estimate of the maximum 10-minute average sustained wind.

           The value given represents the highest 10-min avg MSW assigned

           by any agency.  If from any warning center other than JMA, a

           numbered note below identifies which center's value is given.


       For tropical systems in the NIO basin, an additional column lists

    the alphanumeric storm identifier assigned by the India Meteorological

    Department (IMD) for those systems deemed to have reached cyclonic

    storm (i.e., tropical storm) status by that agency.


       A number in parentheses (e.g. (1) ) following an entry refers to

    a note following the entries for the given basin.   A separate table

    is given for each of the four Northern Hemisphere basins.

   (1) Ioke's JMA tropical storm number after crossing into the Northwest

       Pacific basin was 0612.


   (2) The lowest CP of 1006 mb was assigned by JMA after system had moved

       into the Northwest Pacific basin.


   (3) This system's NRL invest number was '91C', and it occurred at a

       rather high latitude in the Central and Eastern North Pacific.

       The system definitely appeared to be at least subtropical in nature,

       and very possibly was a tropical cyclone.  The intensity is based

       upon a track prepared by Dr. Karl Hoarau of Cergy-Pontoise

       University, Paris.

   (1) The highest 10-min avg MSW was assigned by PAGASA.


   (2) PAGASA classified this system as a tropical depression on 24 June,

       and later that same day upgraded it to tropical storm status.


   (3) The highest 10-min avg MSW estimated by JMA was 60 kts.  PAGASA was

       the only warning agency (known to the author) who upgraded this

       system to typhoon status.


   (4) The PAGASA name for Typhoon Xangsane was Milenyo.


   (5) The peak 1-min avg MSW of 155 kts was obtained from Dvorak analyses

       performed by Dr. Karl Hoarau of Cergy-Pontoise University, Paris,

       and is in agreement with intensity estimates from SAB and AFWA.  The

       highest 1-min avg MSW estimated by JTWC was 140 kts.


   (6) This system appeared to be subtropical in nature.  However, it was

       assigned some tropical "T" Dvorak classifications by SAB who

       designated it as '99W'.  The peak intensity is based upon QuikScat



   (7) Dr. Karl Hoarau estimated the peak intensity for Chebi/Queenie at

       135 kts.   I have used JTWC's peak 1-min avg MSW of 125 kts, which

       is good agreement with SAB's and AFWA's peak Dvorak ratings of

                             ACTIVITY BY BASINS


  ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico


  Activity for December:  No tropical cyclones



                North Atlantic Tropical Activity for December



     In contrast to December, 2005, which was the most active December on

  record in the Atlantic basin, the month of December, 2006, was its

  normal quiet self.  However, there was an interesting-looking system

  in the subtropical eastern Atlantic near 28.7N/34.5W on the 19th which

  exhibited some features often seen in subtropical cyclones.  There was

  some convection with organized curvature, and SSTs were in the 23 to

  25 C range.  The system formed in response to a surface front and the

  cyclone phase space, utilizing GFS runs, kept it as a shallow, symmetric

  warm-core system.    Large-scale atmospheric parameters were not

  particularly unfavorable for further development, but the system appeared

  to move rather rapidly to the east with a frontal-looking convective

  band ahead of it and did not show any additional signs of evolving into

  a subtropical or tropical cyclone.




  SOUTH ATLANTIC (SAT) - Atlantic Ocean South of the Equator


  Activity for December:  Possible subtropical storm



                South Atlantic Tropical Activity for December



     On 12 December Alexandre Aguiar of the MetSul Meteorologia Weather

  Center in Sao Leopoldo, Rio Grande do Sul, Brazil, alerted a tropical

  cyclone discussion group to the existence of a cyclonic system off the

  coast of Brazil roughly near 20.0S/40.0W which appeared to possibly be

  a subtropical system.  The LOW was in the same general vicinity where

  a tropical storm had formed in January, 2004--a couple of months before

  the rather famous (or infamous) Cyclone Catarina.  A ship in the area

  had reported winds of 30 kts with a minimum SLP of 1009 hPa.


     According to Roger Edwards, QuikScat data showed winds generally

  increasing with radial distance from the center, especially toward the

  Brazilian coast, which wouldn't be consistent with a purely tropical

  cyclone.  However, as Roger pointed out, there have been plenty of

  so-called "neutercanes" and other subtropical systems in the North

  Atlantic which have sent mixed signals in that they had similar

  kinematic distribution, yet also some warm-core characteristics.


     Jack Beven pointed out that a system at 20 degrees latitude would not

  normally be expected to have much baroclinicity, which would increase

  its chances of being tropical.  However, to the southeast the system

  appeared to be attached to a frontal system, while to the northwest it

  seemed to be attached to ITCZ convection over Brazil.  Since the LOW

  was never completely isolated from the baroclinic zone/ITCZ cloudiness

  and was always under westerly shear, it seems unlikely that it was a

  purely tropical cyclone.  Jack was of the opinion that it might have

  been more along the lines of the rather well-known Australian East

  Coast cyclones, which typically exhibit monsoon/ITCZ vorticity at low

  levels with baroclinic forcing aloft.


     Whatever its exact thermal nature, the December system constitutes

  another entry into the catalogue of interesting South Atlantic tropical

  and hybrid systems which have been revealed by satellite imagery since

  the first publicized South Atlantic tropical depression in April, 1991.




  NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180


  Activity for December:  No tropical cyclones




  NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180


  Activity for December:  2 tropical depressions **

                          1 tropical storm ++

                          1 typhoon


  ** - classified as tropical depressions by JMA only


  ++ - system was not upgraded to tropical storm status by JTWC



                          Sources of Information



     Most of the information presented below is based upon tropical

  cyclone warnings and significant tropical weather outlooks issued

  by the Joint Typhoon Warning Center of the U. S. Air Force and

  Navy (JTWC), located at Pearl Harbor, Hawaii.   In the companion

  tropical cyclone tracks file, I normally annotate track coordinates

  from some of the various Asian warning centers when their center

  positions differ from JTWC's by usually 40-50 nm or more.   All

  references to sustained winds imply a 1-minute averaging period

  unless otherwise noted.


     Michael V. Padua of Naga City in the Philippines, owner of the

  Typhoon 2000 website, normally sends me cyclone tracks based upon

  warnings issued by the Japanese Meteorological Agency (JMA) and the

  Philippines' Atmospheric, Geophysical & Astronomical Services

  Administration (PAGASA).  A very special thanks to Michael for the

  assistance he so reliably provides.


      In the title line for each storm I have referenced all the cyclone

  names/numbers I have available:   JTWC's depression number, the

  JMA-assigned name (if any), JMA's tropical storm numeric designator,

  and PAGASA's name for systems forming in or passing through their

  area of warning responsibility.



               Northwest Pacific Tropical Activity for December



     Two named tropical cyclones formed during the month of December in the

  Northwest Pacific basin.  Typhoon Utor/Seniang became the sixth (and

  thankfully final!) typhoon of the season to strike the Philippines.

  Following a track somewhat to the south of the previous fall typhoons,

  Seniang passed over the islands of Samar and Leyte and near Mindoro

  Island before emerging into the South China Sea.   Although not nearly

  as destructive and deadly as its immediate predecessor, Durian/Reming,

  Utor nonetheless left at least 30 persons dead with considerable

  destruction at the Boracay Island resort.  The other tropical storm,

  Trami/Tomas, was a weak system which occurred in the Philippine Sea

  during the third week of the month.  (JTWC did not upgrade this system

  to tropical storm status.)


     There were two additional weak systems designated as tropical

  depressions by JMA.   A system east of Guam, near 15.0N/148.0E, was

  referenced as a tropical depression by JMA at 12/0900 UTC.  The system

  was downgraded to a low-pressure area on the next bulletin, but was

  re-upgraded to a tropical depression at 0600 UTC on 10 December, this

  time near 17.0N/139.0E, moving west-northwestward at 10 kts.  JTWC

  assigned a Dvorak classification of T2.0/2.0 on this system at 10/0230

  UTC, but lowered it to T1.0/1.0 three hours later.  Based on JMA's

  shipping bulletins, the depression recurved and by time of the final

  reference at 11/0000 UTC was located near 20.0N/140.0E, moving north-

  eastward at 10 kts.   Another system was briefly referenced as a tropical

  depression near 10.0N/154.0W at 1800 UTC on 10 December, but no further

  mention was made of this system in JMA's shipping bulletins.


     Reports follow on Typhoon Utor and Tropical Storm Tomas.

                               TYPHOON UTOR

                       (TC-25W / TY 0622 / SENIANG)

                             6 - 15 December



  Utor: contributed by the United States, is a Marshallese word meaning

        "squall line"


  A. Introduction and Storm Origins



     Typhoon Utor was the 6th and final typhoon of 2006 to strike the

  Philippines and the 5th in less than three months.  Fortunately, the

  storm was not as deadly as its immediate predecessor, Durian, but

  nonetheless was blamed for at least 30 deaths.  Utor seems to have

  originated within an area of disturbed weather first noted approximately

  265 nm southeast of Chuuk on 2 December.  Convection was flaring over

  a developing LLCC, shear was low, and outflow was favorable.  The system

  remained in the vicinity over the next few days, but on the 6th was

  relocated to a point approximately 300 nm south-southwest of Guam and

  the development potential upgraded to 'fair'.  The system continued to

  consolidate and at 0000 UTC on 7 December, JTWC issued the first warning

  on Tropical Depression 25W, located roughly 95 nm west-southwest of Yap

  and moving westward at 16 kts with an initial intensity of 25 kts.  At

  the same time JMA elevated the system to a 30-kt (10-min avg) depression.



  B. Synoptic History



     TD-25W continued tracking westward south of a strong subtropical ridge

  extending from Guam westward to the Luzon Strait and gradually continued

  to strengthen.  At 07/1800 UTC both JTWC and JMA upgraded the system to

  tropical storm status with JMA naming it Utor.  (PAGASA had assigned the

  name Seniang to the depression after it entered that agency's AOR.)

  Tropical Storm Utor was then located approximately 170 nm north-northwest

  of Palau, tracking west-northwestward at 8 kts.  The newly-christened

  tropical storm intensified slowly at first, but underwent a spurt of

  intensification on the 8th which resulted in its being upgraded to

  Typhoon Utor at 0000 UTC on 9 December by JTWC, JMA and PAGASA.  The

  cyclone was then centered about 390 nm southeast of Manila and tracking

  westward at 12 kts.


     Shortly after being upgraded to typhoon status, Utor/Seniang reached

  the Philippine Archipelago, being located over southeastern Samar Island

  around 09/0600 UTC and near northwestern Leyte Island six hours later.

  By 1800 UTC the storm's center was over the Jintotolo Channel and

  surprisingly had continued to strengthen.  Typhoon Utor/Seniang reached

  its peak estimated intensity of 100 kts at 0000 UTC on 10 December while

  centered just southeast of Mindoro Island or about 145 nm south-southeast

  of Manila.   Interestingly, PAGASA's MSW estimate remained at 65 kts

  during Seniang's entire transit of the archipelago.    Karl Hoarau

  estimates that Utor's winds reached 115 kts (1-min avg) at 10/0000 UTC,

  and this is supported by Dvorak ratings of T6.0/6.0 from both SAB and

  AFWA around that time.   The Dvorak rating from JTWC reached a peak of

  T5.5/5.5 at 09/2330 UTC, so that agency's peak of 100 kts was based

  solely on their own analysis.  Based on reports of some of the damage

  incurred at a resort in the Visayas, it seems very likely indeed that

  Typhoon Utor/Seniang was stronger than most of the warnings were



     Typhoon Utor entered the South China Sea around 1200 UTC on the 10th

  and slowly began to weaken as it moved into a region with the competing

  influences of good outflow but increasing vertical shear and entrainment

  of drier air from the west.  Utor's MSW dropped to 75 kts at 11/0000 UTC

  and remained in the 75-80 kt range for the next day or so.   However,

  at 12/0600 UTC JTWC bumped the intensity back to 90 kts with the storm

  centered about 390 nm southeast of Hainan Island.  Also, JMA increased

  their MSW estimates from 70 kts at 12/0000 UTC to 85 kts twelve hours

  later.  The primary reason for the re-intensification appeared to be very

  good poleward outflow.   The storm's heading was still west-northwesterly

  at this juncture, but became increasingly northwesterly as time went by.

  Utor reached a secondary peak intensity of 95 kts (per JTWC) at 13/0000

  UTC while located approximately 235 nm southeast of Hainan and moving

  northwestward at 5 kts.


     The re-intensification was to be short-lived, however.  After 13/1200

  UTC Utor began to weaken rapidly due to the unfavorable influences of

  increased vertical shear and dry air entrainment.  At 1800 UTC JTWC

  rather drastically reduced the MSW to 65 kts from 90 kts six hours

  earlier, and at 14/0000 UTC dropped the winds to 35 kts and issued their

  final warning with the dissipating system quasi-stationary approximately

  175 nm east-southeast of Hainan Island.  JMA downgraded Utor to a

  tropical depression at 14/0600 UTC, and by 15/0000 UTC had further

  demoted the system to a 20-kt low-pressure area.


     The peak intensity and minimum CP estimated by JMA for Typhoon Utor

  were 85 kts and 945 mb, respectively, during the re-intensification

  episode over the South China Sea.  While traversing the Philippines,

  JMA's peak MSW estimate was 80 kts at 10/0000 UTC.  The highest 10-min

  avg MSW assigned by PAGASA was 70 kts at 12/0000 UTC as Utor/Seniang

  was exiting that agency's AOR.



  C. Damage and Casualties



     According to the Wikipedia online report, Typhoon Utor/Seniang left

  at least 30 persons dead with 8 others missing in the Philippines.  An

  e-mail from Michael Padua of Naga City cited some information from a

  friend of his which stated that "reports from Boracay Island Resort

  via Bombo Radio:  1 dead, 100+ missing, hundreds of boats destroyed.

  The island is stripped of trees and completely isolated.  The island

  hit by a 15 to 20-foot storm surge."

                           TROPICAL STORM TRAMI

                        (TC-26W / TS 0623 / TOMAS)

                             15 - 20 December



  Trami: contributed by Vietnam, is a kind of tree belonging to the rose

         family.  Its flowers are pink or red without a fragrance and is

         used as a decorative tree.


  A. Introduction and Storm Origins



     Tropical Storm Trami (known as Tomas in the Philippines) was the

  final Northwest Pacific tropical cyclone of 2006.   The system was a

  minimal tropical storm per JMA's and PAGASA's analyses, but was treated

  as only a tropical depression by JTWC.  A LLCC developed on 14 December

  about 435 nm east-southeast of Pohnpei.  Microwave and animated multi-

  spectral imagery revealed an area of mid-level cyclonic turning about

  two degrees north of the LLCC.  Outflow was favorable and vertical shear

  was low to moderate.  The disturbance moved westward and by early on

  the 15th was located about 150 nm east-southeast of Pohnpei.  Convection

  was flaring near the LLCC and Pohnpei had reported a surface pressure

  fall of 2.7 mb during the previous 24 hours.  Hence, the potential for

  development was elevated to 'fair'.  JMA began monitoring the system as

  a weak tropical depression in their High Seas Bulletins at 15/0600 UTC.


     The system exhibited a broad circulation with weak multiple LLCCs and

  poorly-organized deep convection on the 15th.   A 15/0713 UTC AMSU image

  had shown no indication of a well-defined LLCC, so the development

  potential was downgraded to 'poor' in an interim STWO issued at 15/1300

  UTC.  By 0600 UTC on the 16th the system was located roughly 445 nm

  southeast of Guam with little change in organization.  However, by

  17/0000 UTC deep convection had become more persistent with a 16/2114

  UTC SSMI image depicting weak banding on the northern periphery of

  the system which appeared to be wrapping into the center of circulation.

  Vertical shear was low with fair divergence aloft, so JTWC once more

  upgraded the development potential to 'fair' at this time.  JMA had

  upped their intensity estimate to 30 kts at 16/1200 UTC, and JTWC issued

  their first warning on Tropical Depression 26W at 17/0300 UTC with the

  center located about 230 nm southwest of Guam.  The MSW was estimated

  at 30 kts and the depression was moving west-northwestward at 17 kts.



  B. Synoptic History



     JMA upgraded the depression to minimal tropical storm status and

  assigned the name Trami at 17/1200 UTC.  Tropical Storm Trami was then

  centered approximately 385 nm west of Guam, moving west-northwestward

  at 18 kts south of a 700-850 mb ridge to the north.   The cyclone moved

  quickly toward the Philippines, posing the threat of yet another typhoon

  strike.  However, Trami struggled against strong vertical shear and an

  approaching cold front.  After the storm entered PAGASA's AOR around

  18/0600 UTC it was named Tomas by that agency, but having two names

  still did not help the storm overcome the unfavorable environment.


     JTWC issued their final warning on Trami at 18/1200 UTC, placing the

  center approximately 700 nm southeast of Okinawa.  Animated infrared

  imagery and an 18/1040 UTC SSMI image depicted a burst of deep convection

  over the north quadrant and no indication of a significant LLCC.  An

  18/0922 UTC QuikScat image had indicated an inverted trough situated

  along 134E with strong convergent flow north of 15N where the deep

  convection was flaring.  An upper-level analysis indicated 30-40 kts

  of vertical shear and strong poleward outflow associated with strong

  mid-latitude westerlies impinging on the system.  JMA and PAGASA main-

  tained Trami/Tomas as a minimal tropical storm through 1800 UTC, but

  both warning agencies downgraded it to depression status at 19/0000 UTC.

  JMA continued to track the weakening system toward the Philippines for

  another day, reducing it to a 20-kt low-pressure area at 20/0000 UTC.


     According to Mike Middlebrooke of the NWS WFO on Guam, QuikScat data

  clearly showed 35-40 kt winds north of the center around 17/2100 and

  18/2100 UTC.  Dvorak classifications from AFWA supported tropical storm

  intensity through 18/1200 UTC, and were actually T3.0/3.0 at 16/2330

  UTC, which was around the time that JTWC initiated warnings.  In fact,

  JTWC's Dvorak rating at 16/2300 UTC was T2.5/2.5 and was T2.0/2.5 at

  17/0530 and 17/1130 UTC.   However, SAB's classifications never rose

  above T2.0/2.0.   The preponderance of the evidence seems to justify

  treating Trami as a minimal tropical storm.



  C. Damage and Casualties



     No reports of damage or casualties resulting from Tropical Storm

  Trami/Tomas have been received.

  NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea


  Activity for December:  No tropical cyclones




  SOUTHWEST INDIAN OCEAN (SWI) - South Indian Ocean West of Longitude 90E


  Activity for December:  1 tropical disturbance

                          1 severe tropical storm **

                          1 intense tropical cyclone


  ** - wind measurements at landfall suggest that this system may have been

       of tropical cyclone (i.e., hurricane) intensity



                           Sources of Information



     The primary sources of tracking and intensity information for

  Southwest Indian Ocean tropical cyclones are the warnings issued by

  the Tropical Cyclone Warning Centre on La Reunion Island, part of

  Meteo France (MFR), and the Regional Specialised Meteorological Centre

  for the basin.    However, tropical cyclones in this region are named

  by the Sub-regional Tropical Cyclone Advisory Centres in Mauritius and

  Madagascar with longitude 55E being the demarcation line between their

  respective areas of naming responsibility.  The La Reunion centre only

  advises these agencies regarding the intensity of tropical systems. 

  References to sustained winds imply a 10-minute averaging period unless

  otherwise stated.


     In the companion tropical cyclone tracks file, I occasionally

  annotate positions from warnings issued by the Joint Typhoon Warning

  Center (JTWC) of the U. S. Air Force and Navy, located at Pearl

  Harbor, Hawaii, when they differ from MFR's coordinates by usually

  40-50 nm or more.  The JTWC warnings are also the source of the

  1-minute average maximum sustained wind values included in the

  tracks file.    Additionally, information describing details of

  satellite imagery and atmospheric circulation features included in

  the narratives is often gleaned from the JTWC warnings.



             Southwest Indian Ocean Tropical Activity for December



     Three numbered tropical systems were tracked by RSMC La Reunion during

  the month of December.  Very small but intense Tropical Cyclone Bondo

  formed shortly after mid-month and followed a westerly track at low

  latitudes for several days, passing just south of the small island of

  Agalega on the 20th at its peak intensity of 110 kts (10-min avg).  The

  storm eventually rounded the tip of Madagascar and moved southward just

  off the island's northwestern coast, finally making landfall near the

  city of Majunga as a severe tropical storm.  A system late in the month

  was numbered as Tropical Disturbance 04 but never strengthened to

  tropical storm status.  A new circulation formed within the larger area

  of disturbed weather and became Tropical Storm Clovis.  The history of

  Tropical Disturbance 04 is contained in the report on Clovis.


     Short reports with satellite pictures and small-scale maps for all

  the Southern Hemisphere systems may be found at the following link:





                             (MFR-03 / TC-05S)

                              17 - 26 December



  A. Introduction and Storm Origins



     Tropical Cyclone Bondo (name contributed by Malawi) formed just west

  of Diego Garcia and moved on a long trajectory which took it near the

  small island of Agalega, later passing just off the northern tip of

  Madagascar and ultimately inland on the west coast of that island near

  Majunga.  The storm was a small but very intense system, reaching an

  estimated peak intensity of 110 kts (10-min avg), or 135 kts (1-min avg)

  from JTWC.    Fortunately, Bondo had weakened to below cyclone intensity

  (i.e., 65 kts) before making landfall in northwestern Madagascar.


     Bondo's origin can be traced to an area of disturbed weather which

  was located west-southwest of Diego Garcia on 15 December.  A satellite

  bulletin issued by JTWC at 2330 UTC on the 16th yielded a Dvorak rating

  of T2.0/2.0, which would imply a tropical depression with maximum 1-min

  avg winds of 30 kts.   MFR issued their first bulletin on Tropical

  Disturbance 03 at 17/1200 UTC, locating the center approximately 450 nm

  west-southwest of Diego Garcia.  A few hours earlier, around 17/0200

  UTC, JTWC had upgraded the development potential to 'good' and issued

  a TCFA.   Deep convection was flaring over a LLCC with convective bands

  wrapping into the center.  An upper-level analysis revealed that the

  disturbance was located within a region of low vertical shear and with

  good divergence and poleward outflow aloft.  The system's organization

  continued to improve, and at 1200 UTC on 18 December JTWC issued their

  first warning on TC-05S, estimating the MSW at 35 kts (1-min avg).

  Six hours later MFR upped Tropical Disturbance 09 to tropical depression

  status, and at 19/0000 UTC the Subregional Tropical Cyclone Advisory

  Centre in Mauritius named the storm Bondo.  Tropical Storm Bondo was

  then located about 240 nm east of Agalega, tracking westward at 11 kts

  along the northern periphery of a mid-level subtropical ridge located

  to the south.  MFR estimated the intensity of Bondo at 40 kts (10-min

  avg) at 19/0000 UTC.



  B. Synoptic History



     To say that Bondo intensified rapidly, or even very rapidly, is an

  understatement.   Shortly after being upgraded to tropical storm status,

  the central pressure began to plummet (as estimated by MFR), dropping

  77 hPa in 24 hours and 61 hPa in 18 hours.  At 19/0000 UTC Bondo was

  a 40-kt tropical storm; eighteen hours later its winds had reached

  105 kts (10-min avg).  The center of this intense tropical cyclone was

  at 19/1800 UTC located about 50 nm east-southeast of Agalega, and six

  hours later had reached its estimated peak intensity of 110 kts only

  about 25 nm southwest of the island.   Although very intense, Bondo

  was an extremely small tropical cyclone with gales extending outward

  only about 20 nm to the north of the center and 40 nm to the south.

  The radius of hurricane-force winds was estimated at only 10 nm (this

  information based upon MFR's 20/0000 UTC warning).  The minimum CP

  estimated by MFR was 915 hPa at 20/0000 UTC, and the peak MSW (1-min

  avg) estimated by JTWC was 135 kts at the same hour.  The tropical

  cyclone at the time was enjoying the combined benefits of low vertical

  shear and excellent radial outflow as it tracked westward at 12 kts

  along the northeastern periphery of a subtropical ridge anchored east

  of La Reunion.


     As Bondo tracked westward it encountered increasing vertical wind

  shear along with reduced polar outflow.  These factors, along with an

  eyewall replacement cycle, caused the storm to weaken significantly

  as it began to approach the northern tip of the island of Madagascar.

  At 0600 UTC on 21 December MFR estimated the intensity at 100 kts.

  Twenty-four hours later Bondo was downgraded to a 55-kt severe tropical

  storm.   The system had now begun tracking southwestward toward the

  large island in response to a developing weakness in the subtropical

  ridge associated with a deepening mid-latitude trough.  At 1200 UTC

  on the 22nd Bondo was located about 100 nm north-northeast of the

  northern tip of Madagascar, moving slowly southwestward at 3 kts.

  MFR's 10-min avg estimate was still 55 kts, but JTWC's 1-min avg MSW

  estimate was 75 kts.  Satellite imagery depicted deep convection rapidly

  redeveloping with spiral curved bands wrapping into the storm's center.

  Also, water vapor imagery revealed that an anticyclone had re-formed

  over the cyclone, resulting in improved outflow.


     Bondo slowly began to re-intensify as the environment became more

  favorable.  The storm continued to track slowly in a south-southwesterly

  direction roughly parallel to the northwestern coastline of Madagascar.

  JTWC upped their MSW estimate to 90 kts (1-min avg) at 23/1200 UTC, while

  MFR estimated the intensity at only 60 kts (10-min avg).  MFR re-upgraded

  Bondo to tropical cyclone (i.e., hurricane) status at 24/0000 UTC with

  the center located about 250 nm north-northeast of Majunga on the western

  coast of Madagascar.  Based on JTWC's analysis, Bondo reached a secondary

  peak intensity of 115 kts at this time, based on Dvorak ratings of T6.0

  from JTWC and AFWA.  SAB's rating, however, at 23/2030 UTC was T5.0/5.0,

  and MFR's was only T4.5/4.5.  MFR upped the MSW to 75 kts at 24/0600 UTC

  where it remained pegged for 24 hours.    As Bondo continued moving

  slightly west of due south along the Malagasy coastline it began to

  slowly weaken due to land interaction and entrainment of drier air.


     Both JTWC and MFR downgraded Bondo to a 60-kt tropical storm at 1200

  UTC on Christmas Day with the center located only around 30 nm north-

  northeast of Majunga.   By 1800 UTC the center had made landfall and

  was rapidly weakening.  JTWC issued their final warning at 26/0000 UTC,

  and MFR downgraded Bondo to a depression at the same time.  The weakening

  system continued to move generally southward over Madagascar with the

  original center dissipating.  The final MFR warning, issued at 1200 UTC

  on 26 December, placed a LLCC back over water approximately 200 nm north

  of Tulear, but noted that it was a "new" LOW which had generated within

  the area of low pressure of the former Tropical Cyclone Bondo.



  C. Meteorological Observations



     According to Philippe Caroffe, Operational Head of RSMC La Reunion,

  the eyewall passed only about 20 nm south of Agalega at peak intensity,

  yet the station there recorded 10-min avg winds of less than gale force.

  The SLP fell to just below 990 hpa--a 15-hPa drop from the ambient

  pressure.  According to the online Wikipedia report, the island of

  Agalega received at least 280 mm of rainfall from the cyclone.



  D. Damage and Casualties



     Two persons were killed in Madagascar, one due to a wall collapsing

  on him, and another missing and presumed dead after taking his family

  out in a canoe.  The missing man's family survived, however.  In Majunga

  38 households were affected, some trees were downed, roofs were damaged,

  and some locations lost electrical power.

                          TROPICAL STORM CLOVIS

                            (MFR-05 / TC-06S)

                         29 December - 4 January



  A. Introduction and Storm Origins



     Severe Tropical Storm Clovis (name contributed by Mauritius) formed

  a short distance southeast of Agalega at the end of December and moved

  on a general southwesterly trajectory which took it inland on the

  eastern coast of Madagascar in early January.  Clovis' beginnings lay

  within an area of convection which had persisted roughly 400 nm west-

  northwest of Diego Garcia on 24 December.  Convective banding was

  beginning to wrap into a developing LLCC and upper-level diffluence was

  good, but vertical shear was moderate.   JTWC upgraded the system's

  potential for development to 'fair' in a STWO issued at 24/1800 UTC.

  MFR initiated bulletins on Tropical Disturbance 04 at 1200 UTC on the

  25th, placing a weak center about 300 nm west of Diego Garcia.  Over

  the next couple of days the system drifted toward the west-southwest

  but remained weak.  JTWC issued a TCFA at 26/2330 UTC as the LLCC

  had moved under an area of deep convection in a region of low vertical



     By 27/1800 UTC the disturbance was situated about 90 nm north of

  Agalega within a region of moderate to high vertical shear which had

  displaced the deep convection to the west of the LLCC.  Twenty-four

  hours later Tropical Disturbance 04 had drifted to a position about

  135 nm west of Agalega.  JTWC continued to re-issue TCFAs on this

  system as it was moving into a region of weaker vertical shear.  However,

  the system was located under convergent flow associated with the north-

  western periphery of an upper-level, near-equatorial ridge which was

  inhibiting outflow.   MFR's bulletin at 28/1800 UTC stated that the

  system's organization did not warrant the issuance of regular warnings.

  This warning, however, turned out to be the final one on Tropical

  Disturbance 04.


     At 1200 UTC on 29 December MFR issued the first statement on Tropical

  Disturbance 05, which contained the following paragraph (slightly



     "The low-level circulation center monitored and numbered 04 has

  dissipated but the convective activity associated with ex-Tropical

  Disturbance 04 has persisted.  During the night, several related and

  short-lived centers have probably existed at the mercy of convective

  pulsations, mainly east of 55E.  Last satellite imagery now shows a new

  clockwise circulation organizing around a new center which appears to

  be the main one.  The dissipation of the first monitored system and the

  genesis of this new one justifies the re-numbering."


     JTWC's STWO issued at 29/1400 UTC also relocated the area of interest

  further to the east.  The previously issued TCFA for the region remained

  in effect since the environment had become somewhat more favorable.

  MFR's first bulletin on Tropical Disturbance 05 located the center

  125 nm southeast of Agalega at 29/1200 UTC.  The system slowly

  strengthened as it drifted west-southwestward over the next couple of

  days.   MFR upgraded it to a 30-kt tropical depression at 0600 UTC on

  31 December, and at the same time JTWC issued their first warning on

  TC-06S with 35-kt winds (1-min avg).   Six hours later MFR upgraded

  the depression to Tropical Storm Clovis, located about 300 nm southwest

  of Agalega with the MSW estimated at 40 kts.   At the time of its

  upgrade Clovis was tracking south-southwestward at 9 kts.  (Note: Storms

  in this basin are actually named by Subregional Tropical Cyclone Advisory

  Centres in Mauritius (east of 55E) and Magadascar (west of 55E).  Since

  the center of this system was located just west of the line of

  demarcation, presumably the name was bestowed by Madagascar's

  Meteorological Service.)



  B. Synoptic History



     Newly-christened Tropical Storm Clovis wasted no time in intensifying.

  At 1800 UTC on 31 December (six hours after being upgraded), MFR bumped

  the MSW up to 60 kts, although this was reduced slightly on the next

  warning.  The system was heading toward a weakness in the subtropical

  ridge axis caused by a high-amplitude trough south of the Mozambique

  Channel.  Throughout the remainder of its life until making landfall

  in Madagascar, Clovis followed a fairly smooth south-southwesterly track.

  Winds remained in the 50-55 kt range (per MFR) on 1 January, but were

  increased to 60 kts at 0600 UTC on 2 January, the storm being then

  located about 375 nm west of Mauritius.


     Clovis' winds remained at 60 kts for 24 hours before being lowered

  to 50 kts at 03/0600 UTC.  JTWC's estimated MSW (1-min avg) reached

  65 kts at 02/1800 UTC, based on CI numbers of 4.0 from JTWC, AFWA and

  SAB.     MFR's Dvorak rating during this time also was T4.0/4.0,

  corresponding to a 10-min avg intensity of 60 kts.   As Clovis neared

  Madagascar, a transient shortwave ridge built in poleward of the storm,

  resulting in a more westerly track at a slower pace.  Tropical Storm

  Clovis made landfall in eastern Madagascar north of Mananjary around

  0600 UTC on the 3rd with winds estimated at 50 kts (65 kts 1-min avg

  MSW from JTWC).   After the system had made landfall, it remained

  quasi-stationary on the coast or just inland and gradually weakened.

  JTWC issued their final warning at 04/0600 UTC, and MFR finalized Clovis

  six hours later, noting that winds of 20-25 kts might still be

  experienced along the coastline and out to sea for about 30 nm.



  C. Meteorological Observations



     A ship in the vicinity of 16.1S/55.1E reported ENE winds of 35-40 kts

  at 2245 UTC on 30 December with a SLP of 1009 hPa and 3 m seas.  This

  observation was 6-12 hours before Clovis was upgraded to tropical storm

  status by any of the warning centers, and suggests that perhaps the

  system was stronger than thought.  This fits in with the apparent rapid

  intensification reflected in the warnings from 31/0600 to 31/1800 UTC.

  AMSU data taken at 31/0949 UTC indicated a system near hurricane force.


     The online Wikipedia report notes that Clovis passed about 11 nm

  northwest of Tromelin Island around 1700 UTC on 31 December with winds

  of 54 kts, gusting to 70 kts.  It is assumed that this refers to a wind

  observation measured on the island.   At 1400 UTC the station on the

  island measured a peak 10-min avg sustained wind of 49 kts with peak

  gusts to 64 kts, and the wind was still increasing.


     Karl Hoarau sent some observations from Madagascar which suggest that

  Clovis was stronger than analyzed by JTWC and MFR at landfall.  The small

  airport of Nosy Varika (20.55S/48.6E) reported a 10-min avg wind of

  59 kts at 03/0530 UTC with gusts exceeding 97 kts.    Gusts of this

  magnitude would suggest a 10-min avg wind of about 68 kts, or a 1-min avg

  wind of 78 kts.  A 37-GHz image at 03/0230 UTC (a few hours before land-

  fall) showed a well-defined eye in the low levels.



  D. Damage and Casualties



     No reports of damage of casualties resulting from Severe Tropical

  Storm Clovis had been received.

  Activity for December:  No tropical cyclones



                 Northwest Australia/Southeast Indian Ocean

                       Tropical Activity for December



     A tropical LOW formed off Western Australia on 31 December.

  Peripheral gales began on 1 January and on the 2nd the system was named

  Tropical Cyclone Isobel.  Isobel moved southward and made landfall in

  Western Australia on the 3rd.  It appears that during a post-storm

  analysis and review of Isobel, a determination was made that the system

  was not a true tropical cyclone and Isobel has since been declassified. 

  A full report on Isobel will be included in the January summary.






  Activity for December:  No tropical cyclones




  SOUTH PACIFIC (SPA) - South Pacific Ocean East of Longitude 160E


  Activity for December:  No tropical cyclones



                 South Pacific Tropical Activity for December



     At the beginning of the month Tropical Depression 05F/TC-04P was

  operating over waters east and southeast of Guadalcanal in the Solomon

  Islands.  The system began to weaken on the 2nd and had dissipated by

  the 4th.  A short report on this depression may be found in the November

  summary.  No other systems were designated as tropical depressions by

  RSMC Nadi during the month of December.  The tropics lay completely

  quiet after the spate of activity from late October through November

  which had produced five numbered systems, including two of hurricane

  intensity (Xavier and Yani).

  varied types of tropical cyclone information are archived.  Many readers

  will know about these already, but for the benefit of those who don't,

  I wanted to include them.

     I am not aware at the moment of any other TCWC which archives all

  its tropical cyclone warning/advisory products for public access, but

  if I learn of any, I will add them to this list.


  (3) Satellite Imagery



     Satellite images of tropical cyclones in various sensor bands are

  available on the NRL Monterrey and University of Wisconsin websites,

  courtesy of Jeff Hawkins and Chris Velden and their associates.  The

  links are:


  On the NRL site, the link to past years can be found in the upper left

  corner of the screen.  For the CIMSS site, a link to data archives is

  located in the lower left portion of the screen.


     Additional tropical satellite imagery, along with looping ability for

  composite microwave imagery for the Western Hemisphere north of the

  equator, can be found at:


  (1) For the Eastern North Pacific:


  (2) For the Atlantic, Gulf of Mexico and Caribbean Sea:


     I'm sure there are other sites with available imagery available, and

  as I learn of them, I will add the links to this list.




                               EXTRA FEATURE


     In order to shorten the amount of typing in preparing the narrative

  material, I have been in the habit of freely using abbreviations and

  acronyms.   I have tried to define most of these with the first usage

  in a given summary, but I may have missed one now and then.  Most of

  these are probably understood by a majority of readers but perhaps a

  few aren't clear to some.  To remedy this I developed a Glossary of

  Abbreviations and Acronyms which I first included in the August, 1998

  summary.  I don't normally include the Glossary in most months in

  order to help keep them from being too long.  If anyone would like to

  receive a copy of the Glossary, please e-mail me and I'll be happy

  to send them a copy.




  AUTHOR'S NOTE:  This summary should be considered a very preliminary

  overview of the tropical cyclones that occur in each month. The cyclone

  tracks (provided separately) will generally be based upon operational

  warnings issued by the various tropical cyclone warning centers.  The

  information contained therein may differ somewhat from the tracking and

  intensity information obtained from a "best-track" file which is based

  on a detailed post-seasonal analysis of all available data. Information

  on where to find official "best-track" files from the various warning

  centers will be passed along from time to time.


    The track files are not being sent via e-mail.  They can be retrieved

  from the archive sites listed below.  (Note: I do have a limited e-mail

  distribution list for the track files.    If anyone wishes to receive

  these via e-mail, please send me a message.)


    Both the summaries and the track files are standard text files

  created in DOS editor.  Download to disk and use a viewer such as

  Notepad or DOS editor to view the files.


     The first summary in this series covered the month of October,

  1997.   Back issues can be obtained from the following websites

     Another website where much information about tropical cyclones may

  be found is the website for the UK Meteorological Office.  Their site

  contains a lot of statistical information about tropical cyclones

  globally on a monthly basis.  The URL is:





     JTWC now has available on its website the Annual Tropical Cyclone

  Report (ATCR) for 2005 (2004-2005 season for the Southern Hemisphere).

  ATCRs for earlier years are available also.


     The URL is:



     Also, TPC/NHC has available on its webpage nice "technicolor"

  tracking charts for the 2006 Atlantic and Eastern North Pacific

  tropical cyclones; also, storm reports for all the 2006 Atlantic

  and Eastern North Pacific cyclones are now available, as well as

  track charts and reports on storms from earlier years.
