DISCUSSION AND OUTLOOK
At 1000 PM CDT (0300 UTC), the center of Tropical Storm Gamma was located near latitude 21.3 North, longitude 88.0 West. Gamma is moving toward the northwest near 7 mph (11 km/h) and a turn toward the north-northwest with decreasing forward speed is expected on Sunday, followed by a turn to the west or west-southwest Sunday night or Monday. On the forecast track, the center of Gamma will move offshore of the Yucatan Peninsula and over the southern Gulf of Mexico on Sunday and pass near or north of the northern coast of the Yucatan Peninsula Monday and Tuesday.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Little change in strength is forecast during the next few days. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 990 MB (29.24 inches).


HAZARDS AFFECTING LAND
RAINFALL: Gamma is expected to produce storm total rainfall of 4 to 8 inches across portions of the Yucatan Peninsula and far western Cuba, with maximum rainfall amounts as high as 10 to 15 inches possible across northeastern Quintana Roo and northern Yucatan. This rainfall may produce life-threatening flash floods.

A separate area of significant rain is possible in the Mexican states of Campeche, Tabasco, northern Chiapas, and southeast Veracruz, with rainfall of 6 to 8 inches and isolated maximum amounts of 12 inches. This rainfall may produce life-threatening flash floods and mudslides. The storm will also result in an area of heavy rains to the south from southern Guatemala towards the Gulf of Fonseca region between eastern El Salvador, southern Honduras, and northwest Nicaragua, with accumulations of 4 to 6 inches and isolated maximum amounts of 8 inches.

WIND: Tropical storm conditions should continue within the Tropical Storm Warning area on the east coast of the Yucatan Peninsula for the next few hours, and on the north coast of the Yucatan through Sunday. Tropical Storm conditions are possible within the Tropical Storm Watch area on Monday.
