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). A very special thanks to Michael for the assistance he so reliably provides.

Their highest estimated 10-min avg MSW was 45 kts. NMCC and HKO, along with JMA, rated the system as no more than a 30-kt (10-min avg) tropical depression. The CWB of Taiwan also classified the system as a tropical depression, but did not assign any explicit wind estimations.

According to Huang Chunliang, this system was the Indian Ocean continuation of former Tropical Cyclone Evan which formed in the Gulf of Carpentaria on 1 March and quickly moved inland and weakened. The Perth TCWC issued gale warnings on the remnants of Evan beginning on 3 March in the anticipation that it would regain tropical cyclone status, but were dropped on the 6th after it had shown no signs of redevelopment. ************************************************************************* ************************************************************************* NORTHWEST AUSTRALIA/SOUTHEAST INDIAN OCEAN (AUW) - Longitude 90E to 135E Sources of Information ---------------------- The track coordinates as well as the central pressure and 10-minute average maximum sustained wind estimates were obtained from warnings issued by the Tropical Cyclone Warning Centres at Perth, Western Australia, and Darwin, Northern Territory.

Also, in the Fiji bulletins, this system at one point was referred to as 09F due to a typographical error--that was corrected in the 31/2100 UTC Tropical Disturbance Summary. No value was given for the MSW in the final two summaries, but a separate gale warning was issued as late as 31/1900 UTC. ************************************************************************* ************************************************************************* !!!!!! 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.
