DISCUSSION AND OUTLOOK
At 800 AM AST (1200 UTC), the center of Tropical Storm Kirk was located near latitude 13.6 North, longitude 58.7 West. Kirk is moving toward the west-northwest near 16 mph (26 km/h), and this general motion with a slight decrease in forward speed is expected over the next few days. On the forecast track, the center of Kirk will move across the Lesser Antilles within the Tropical Storm Warning area by this evening.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Gradual weakening is anticipated during the next couple of days, but Kirk is forecast to move across the Lesser Antilles and into the eastern Caribbean Sea as a tropical storm.
Tropical-storm-force winds extend outward up to 140 miles (220 km), mostly north and east of the center.
The estimated minimum central pressure is 1000 mb (29.53 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected to first reach the warning area this afternoon, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area by this afternoon.
RAINFALL: Kirk is expected to produce total rainfall of 4 to 6 inches across the northern Windward and southern Leeward Islands with isolated maximum totals up to 10 inches across Martinique and Dominica. These rains may produce life-threatening flash floods and mudslides. Across eastern Puerto Rico, Kirk is expected to bring 2 to 4 inches with isolated maximum totals of 6 inches by Friday and Saturday.
