More thunderstorms formed near the center of a small low pressure system over the Bay of Campeche and the National Hurricane Center classified the low as Tropical Depression Nine (TD9) at 11:00 p.m. EDT on Tuesday. The center of TD9 was located at latitude 19.4°N and longitude 92.9°W which put it about 160 miles west of Campeche, Mexico and about 850 miles west-southwest of Key West, Florida. TD9 was moving toward the east at 6 m.p.h. The maximum sustained wind speed was 35 m.p.h. and the minimum surface pressure was 1000 mb. The government of Mexico has issued a Tropical Storm Warning for the portion of the coast from Celestun to Frontera.
Westerly winds in the upper levels are still creating wind shear over the top of TD9 and most of the thunderstorms are located in the eastern half of the circulation. However, the upper level wind speed is expected to diminish and TD9 is likely to intensify into Tropical Storm Hanna on Wednesday. The westerly winds are also likely to continue to push TD9 toward the east or east-northeast during the next 24 hours.
