Note #2: No intermediate bulletin was issued at 0600 UTC, and Gabrielle was downgraded to depression status at 0900 UTC. However, based on a peak recon FLW of 53 kts at 0247 UTC, it seems likely that the system was still a tropical storm at 0600 UTC. ************************************************************************* Storm Name: INGRID Cyclone Number: 08 Basin: ATL Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 07 SEP 12 1200 13.1 N 44.2 W 1007 30 07 SEP 12 1800 13.4 N 45.0 W 1006 30 07 SEP 13 0000 13.3 N 46.1 W 1006 30 07 SEP 13 0600 13.8 N 47.1 W 1006 30 07 SEP 13 1200 13.8 N 47.7 W 1006 30 See Note #1 07 SEP 13 1800 14.1 N 48.2 W 1006 30 07 SEP 14 0000 14.6 N 48.5 W 1002 35 07 SEP 14 0600 14.9 N 49.0 W 1002 35 07 SEP 14 1200 15.1 N 49.7 W 1004 45 See Note #2 07 SEP 14 1800 15.4 N 50.3 W 1004 40 " 07 SEP 15 0000 15.7 N 51.1 W 1005 35 07 SEP 15 0600 16.3 N 52.3 W 1006 35 07 SEP 15 1200 16.3 N 53.3 W 1006 30 07 SEP 15 1800 16.4 N 54.6 W 1006 30 07 SEP 16 0000 16.8 N 55.3 W 1006 30 07 SEP 16 0600 16.9 N 56.4 W 1006 30 07 SEP 16 1200 17.1 N 57.5 W 1006 30 07 SEP 16 1800 17.3 N 58.2 W 1006 30 07 SEP 17 0000 17.3 N 59.0 W 1010 25 07 SEP 17 0600 17.4 N 59.7 W 1010 25 Final NHC advisory 07 SEP 17 1200 18.0 N 60.0 W 1010 20 07 SEP 17 1800 18.0 N 61.0 W 1010 20 07 SEP 18 0000 18.0 N 61.5 W 1011 20 07 SEP 18 0600 18.0 N 62.0 W 1010 20 07 SEP 18 1200 19.0 N 62.0 W 1012 20 Note #1: A 13/0900 UTC QuikScat pass indicated a few unflagged 35-kt wind vectors just east and south of the center, suggesting that TD-08 could have been a tropical storm for a few hours. However, by the 1500 UTC advisory time, the system's satellite appearance suggested weakening. Note #2: The 14/1500 UTC advisory MSW was 40 kts. However, earlier (at 1118 UTC) the SFMR reported winds to 51 kts in the SW quadrant, and T-numbers from SAB and TAFB were T3.0 at 1200 UTC. Given that by the 1500 UTC advisory time, the system's satellite signature was beginning to degrade a little due to increasing shear, it seems very possible that 45 kts is a good estimate for the MSW at 1200 UTC. Similarly, the MSW was not reduced to 35 kts until the 2100 UTC advisory, so I have retained the 1500 UTC value of 40 kts for the 1800 UTC synoptic hour data point. ************************************************************************* Storm Name: HUMBERTO Cyclone Number: 09 Basin: ATL Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 07 SEP 12 1200 27.8 N 95.2 W 1006 30 07 SEP 12 1800 28.3 N 95.0 W 1005 40 07 SEP 13 0000 28.8 N 94.8 W 998 45 07 SEP 13 0600 29.5 N 94.4 W 992 70 MSW 55 kts at 0300Z 07 SEP 13 1200 30.3 N 93.6 W 987 70 Inland/See Note #1 07 SEP 13 1800 31.0 N 92.9 W 997 40 See Note #2 07 SEP 13 2100 31.4 N 92.6 W 1003 30 Final NHC advisory 07 SEP 14 0300 31.8 N 91.5 W 1007 22 HPC advisory 07 SEP 14 0900 32.5 N 91.2 W 1008 17 07 SEP 14 1500 32.8 N 89.3 W 1010 13 07 SEP 14 2100 34.0 N 85.0 W 1012 13 Final HPC advisory Note #1: The center of Hurricane Humberto crossed the Texas coast just east of High Island at 0700 UTC with the MSW estimated at 75 kts.

Note #2: From the 25/0300 UTC NHC discussion: "A QuikScat pass at 24/2136 UTC indicated that the circulation of Jerry had opened up into a sharp trough within the southwesterly flow ahead of a large extratropical LOW. Consequently, Jerry is no longer a tropical cyclone and this is the last advisory. As Jerry accelerated this evening, maximum winds at the base of the trough increased to about 40 kts according to the QuikScat data; hence, the apparent upgrade back to a tropical storm. The remnants of Jerry should continue to race northeastward and become further entrained into the extratropical circulation." ************************************************************************* Storm Name: KAREN Cyclone Number: 12 Basin: ATL Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 07 SEP 25 0000 9.9 N 35.7 W 1006 30 07 SEP 25 0600 10.3 N 37.2 W 1005 35 07 SEP 25 1200 10.6 N 38.0 W 1005 35 07 SEP 25 1800 10.9 N 39.2 W 1005 35 07 SEP 26 0000 10.9 N 40.4 W 1005 35 07 SEP 26 0600 11.1 N 41.5 W 1000 45 07 SEP 26 1200 11.7 N 42.4 W 990 60 07 SEP 26 1800 12.1 N 43.1 W 990 60 07 SEP 27 0000 12.8 N 44.6 W 996 60 See Note 07 SEP 27 0600 13.3 N 46.1 W 998 55 07 SEP 27 1200 13.5 N 46.8 W 1004 55 07 SEP 27 1800 14.2 N 47.9 W 1005 50 07 SEP 28 0000 14.6 N 49.0 W 1005 50 07 SEP 28 0600 14.0 N 49.4 W 1008 40 07 SEP 28 1200 14.6 N 49.0 W 1009 35 07 SEP 28 1800 16.0 N 49.3 W 1008 35 07 SEP 29 0000 16.0 N 51.5 W 1008 35 Relocation 07 SEP 29 0600 16.3 N 52.5 W 1008 35 07 SEP 29 1200 16.5 N 53.5 W 1009 30 07 SEP 29 1800 17.0 N 54.0 W 1009 30 Final NHC advisory 07 SEP 30 0000 16.0 N 54.0 W 1009 25 From Trop WX Discussion 07 SEP 30 0600 16.0 N 53.0 W 1010 25 Remnant LOW 07 SEP 30 1200 18.0 N 56.0 W 1012 20 07 SEP 30 1800 17.0 N 58.0 W 1011 20 Note: A NOAA Hurricane Hunter plane investigating Karen during the evening of the 26th found surface winds of 62 kts.

S. Air Force and Navy, located at Pearl Harbor, Hawaii. The central pressure and 10-minute average maximum sustained wind estimates for most systems were obtained from warnings issued by the Japanese Meteorological Agency (JMA), which is the World Meteorological Organization's Regional Specialised Meteor- ological Centre for the basin. In a few instances, information from warnings issued by other Asian warning centers may have been utilized. The center position coordinates from JMA and other centers were com- pared with those from JTWC and annotations made in the Remarks column when the differences in general amounted to 40-50 nm or more. Michael V. Padua of Naga City in the Philippines, owner of the Typhoon 2000 website, sends me cyclone tracks based upon warnings issued by the Japanese Meteorological Agency and the Philippines' Atmospheric, Geophysical & Astronomical Services Administration (PAGASA).

1800 16.9 N 100.6 E 1004 20 " Note: Interestingly, while JMA weakened the system on 28 September and downgraded it to a low-pressure area (LPA), PAGASA upgraded Hanna to minimal tropical storm status. As I have usually done in past years, I have based the track on the warning agency reporting the highest intensity. During the phase of its life in the Philippine Sea, Hanna was a broad, monsoon depression-type of tropical cyclone; hence, it is not surprising that there are significant differences in center position between the two agencies. Jose Garcia of Puerto Rico reports that a check of QuikScat data about six hours before landfall in Luzon revealed some 30-35 kt vectors, so it appears likely that gale-force winds were present in Hanna when it made landfall in the Philippines. Remarks in the JTWC SWTOs on 29 September suggest that the old LLCC dissipated east of the Philippines and that the surface development in the South China Sea was a new LLCC forming under the mid-level center of the old disturbance. However, both JMA's and PAGASA's warnings show continuity, tracking the former TD/TS Hanna across Luzon, so I have followed those agencies with the above track. ************************************************************************* ************************************************************************* !!!!!! IMPORTANT NOTE - PLEASE READ !!!!!! To repeat the caveat which is included in the Author's Note at the end of the cyclone summaries--the tropical cyclone tracks I prepare are based upon the operational warnings/advisories/ advices/bulletins which are issued by the various tropical cyclone warning agencies around the world. Users of these tracks should be aware that they are preliminary and subject to revision during post-seasonal analyses of the cyclones by the forecasters and analysts at the several warning centers. For the Atlantic and Northeast Pacific basins, official tropical cyclone reports and "best tracks" can be found at the website of the Tropical Prediction Center/National Hurricane Center: The Joint Typhoon Warning Center's website contains links to their Annual Tropical Cyclone Reports which include that agency's "best tracks" for tropical cyclones in the Northwest Pacific basin, the North Indian Ocean, and the Southern Hemisphere: SPECIAL NOTE: Back issues of the global tropical cyclone summaries and monthly cyclone track files can be obtained at the following websites: PREPARED BY: Gary Padgett garyp@alaweb.com SIGNIFICANT CONTRIBUTIONS BY: Michael V.
