DISCUSSION AND OUTLOOK

At 1100 AM EDT (1500 UTC), the center of Tropical Depression Fourteen was located near latitude 16.6 North, longitude 84.1 West. The depression is moving toward the northwest near 14 mph (22 km/h). A slower northwestward motion is expected over the next couple of days, followed by an increase in speed by Sunday and Monday. On the forecast track, the center of the depression will move away from the coast of Honduras today and will approach the east coast of the Yucatan Peninsula of Mexico on Saturday. The center will then cross the northeastern part of the Yucatan Peninsula Saturday night and move over the central Gulf of Mexico toward the northwestern Gulf on Sunday and Monday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and the depression is expected to become a tropical storm later today. The system is forecast to be near or at hurricane strength when it reaches the Yucatan Peninsula of Mexico late Saturday. Some weakening is expected as it moves over the Yucatan Peninsula Saturday night. Afterward, restrengthening is forecast on Sunday as it moves offshore and enters the southern Gulf of Mexico.

The estimated minimum central pressure is 1008 MB (29.77 inches).

HAZARDS AFFECTING LAND

WIND: Tropical storm conditions are expected to first reach the eastern Yucatan coast within the warning area by Saturday afternoon, making outside preparations difficult or dangerous. Hurricane conditions are also possible within the watch area by late Saturday.

Tropical storm conditions are possible within the tropical storm watch area on the northern coast of the Yucatan Peninsula Saturday night and Sunday.

Tropical storm conditions are still possible over the Bay Islands of Honduras today.

RAINFALL: The depression is expected to produce the following rainfall accumulations through Sunday:

Eastern portions of the Mexican states of Quintana Roo and Yucatan: 3 to 6 inches, isolated maximum totals of 10 inches. This rainfall may result in areas of flash flooding.
