GLOBAL TROPICAL CYCLONE TRACKS - MAY 2000 ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico NOTE: The information presented below on a possible subtropical disturbance southeast of Bermuda was sent to me by Michael Pitt. Tropical Weather Discussions issued by TPC classified the system as a complex system with an upper-level LOW with supporting fronts and an associated surface LOW. The Air Force Weather Agency (AFWA) assigned Dvorak ratings on the disturbance for about 30 hours on 19 and 20 May.

The MSW are based on a 1-min averaging period, which is used by all U.S. civilian and military weather services for tropical cyclone warnings.

Comparisons were made with track coordinates given in advisories from the meteorological services of Japan (JMA) and the Philippines (PAGASA). In general, whenever the center position differed by more than 40-50 nm from JTWC's, an entry was made in the Remarks column. The 1-min avg MSW were taken from the JTWC advisories while the 10-min avg MSW were obtained from PAGASA's advisories if the storm was in PAGASA's area of responsibility; otherwise, they were gleaned from JMA's advisories or high seas forecasts. In a few cases the 10-min MSW given by PAGASA and JMA did not agree; in those cases I reported the higher value. The estimates of central pressure were obtained from JMA's advisories. Michael V. Padua, owner of the Typhoon 2000 webpage sent me the PAGASA and JMA tracks for these systems--a special thanks to Michael for his assistance.
