GLOBAL TROPICAL CYCLONE TRACKS - JUNE 2007 !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!! ************************************************************************* ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico Sources of Information ---------------------- The track coordinates, central pressure and 1-minute average maximum sustained wind values were obtained from the operational forecast/advisories issued by the Tropical Prediction Center/National Hurricane Center located in Miami, Florida.

A 1-minute averaging period is the standard used by all U. S. civilian and military warning services for tropical cyclone warnings.

S. Air Force and Navy, located at Pearl Harbor, Hawaii. Occasionally some information may have been gleaned from the daily tropical weather outlooks and other bulletins issued by the Indian Meteorological Department (IMD), which is the World Meteorological Organization's Regional Specialised Meteor- ological Centre for the basin. The reported maximum sustained winds are based on a 1-minute averaging period, which is used by all U. S. civilian and military weather services for tropical cyclone warnings. For synoptic observations in the North Indian Ocean region, both 10-minute and 3-minute average winds are employed, but IMD makes no attempt to modify the Dvorak scale for estimating tropical cyclone intensity; hence, a 1-minute average MSW is implied.

At 06/0600 UTC I chose to use IMD's MSW of 80 kts since it was more in line with the consensus of Dvorak estimates from the several agencies. The IMD estimate of 90 kts at 06/1200 UTC was equated with a T-number of T4.5, and seems too high considering the fact that Gonu was weakening, and given that on the previous day 970 hPa was matched with a MSW of 80 kts. ************************************************************************* Storm Name: None Cyclone Number: 03B Basin: NIO (Storm unofficially named YEMYIN by Pakistani Meteorological Service) Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 07 JUN 21 0300 15.5 N 86.0 E 25 IMD bulletin 07 JUN 21 0600 15.6 N 85.2 E 30 JTWC satellite bulletin 07 JUN 21 1200 16.1 N 83.8 E 35 JTWC warning 07 JUN 21 1800 16.0 N 83.6 E 35 IMD: 16.5N/82.5E 07 JUN 22 0000 15.6 N 81.3 E 35 See Note 07 JUN 22 0600 15.7 N 80.1 E 35 Inland/Final JTWC wrng 07 JUN 22 1200 16.3 N 79.3 E 30 JTWC & AFWA sat buls 07 JUN 22 1800 16.6 N 79.1 E 25 JTWC satellite bulletin 07 JUN 23 0000 16.9 N 76.6 E 20 " 07 JUN 23 0600 19.3 N 76.6 E 15 " 07 JUN 23 1200 20.2 N 75.5 E 15 " 07 JUN 23 1800 20.7 N 74.6 E 15 " 07 JUN 24 0230 21.6 N 72.0 E 15 " 07 JUN 24 0600 21.4 N 71.6 E 20 " 07 JUN 24 1200 22.0 N 70.7 E 20 " 07 JUN 24 1800 22.6 N 70.0 E 25 AFWA: 21.1N/67.6E 07 JUN 25 0000 22.4 N 68.9 E 30 AFWA: 22.2N/67.6E 07 JUN 25 0600 22.9 N 67.3 E 35 JTWC warning 07 JUN 25 1200 23.5 N 66.4 E 35 IMD: 30 kts 07 JUN 25 1800 24.2 N 66.3 E 45 07 JUN 26 0000 25.1 N 65.2 E 50 07 JUN 26 0600 25.7 N 64.2 E 45 Inland in Pakistan 07 JUN 26 1200 26.2 N 63.0 E 40 07 JUN 26 1800 26.2 N 62.6 E 30 07 JUN 27 0000 27.1 N 62.7 E 25 AFWA & JTWC sat buls 07 JUN 27 0600 27.7 N 63.6 E 15 JTWC satellite bulletin Note: The IMD classified this system as a deep depression, implying peak winds of 30 kts. While JTWC assigned a peak 1-min avg of 35 kts, neither JTWC nor AFWA assigned Dvorak T-numbers exceeding T2.0. The only bulletin available to the author with a Dvorak estimate of T2.5 was the SAB bulletin issued at 22/0230 UTC. However, Dr. Karl Hoarau performed his own Dvorak analysis of the system and assigns a peak intensity of 45 kts at 22/0000 UTC, shortly before landfall in India. The preceding comments apply only to the Bay of Bengal portion of this system. In its Arabian Sea phase the system was considerably stronger, and based on most Dvorak intensity estimates, microwave imagery, and at least one SLP observation a few hours after landfall, the storm was probably a Category 1 hurricane when it made landfall in Pakistan. IMD, who has official naming responsibility for the North Indian Ocean basin, again did not classify the system above deep depression status; hence, they did not name the storm. However, the Meteorological Service of Pakistan applied the name Yemyin to the cyclone in their warnings, and this was picked up by the press and given widespread dissemination. ************************************************************************* Storm Name: None Cyclone Number: 04B Basin: NIO Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 07 JUN 27 0000 17.2 N 89.0 E 25 AFWA satellite bulletin 07 JUN 27 0600 17.7 N 87.9 E 25 " 07 JUN 27 1200 16.8 N 87.3 E 25 JTWC & AFWA sat buls 07 JUN 27 1800 16.1 N 87.1 E 25 " 07 JUN 28 0000 16.7 N 87.1 E 30 JTWC satellite bulletin 07 JUN 28 0600 17.4 N 86.6 E 30 " 07 JUN 28 1200 18.2 N 86.3 E 35 JTWC warning 07 JUN 28 1800 19.0 N 86.3 E 45 JTWC & AFWA sat buls 07 JUN 29 0000 19.7 N 86.0 E 45 JTWC warning 07 JUN 29 0600 20.3 N 84.6 E 45 JTWC satellite bulletin 07 JUN 29 1200 21.4 N 83.6 E 35 Inland/JTWC warning 07 JUN 29 1800 21.7 N 82.5 E 30 JTWC satellite bulletin 07 JUN 30 0000 22.0 N 81.2 E 25 07 JUN 30 0600 23.1 N 80.7 E 25 07 JUN 30 1200 23.4 N 79.3 E 25 07 JUN 30 1800 22.9 N 78.3 E 20 07 JUL 01 0000 23.0 N 77.7 E 20 Note: The highest classification assigned to this system by IMD was 'deep depression', i.e., 28-33 kts. ************************************************************************* ************************************************************************* !!!!!! 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.
