DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Kirk was located by Air Force Reserve Hurricane Hunter aircraft near latitude 13.0 North, longitude 57.0 West. Kirk is moving toward the west-northwest near 16 mph (26 km/h), and this general motion is expected to continue 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 Thursday or Thursday evening. Data from the Hurricane Hunter plane indicate that maximum sustained winds have decreased to 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) mainly to the north and east of the center. The minimum central pressure based on the latest aircraft data is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the warning area by Thursday afternoon, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area by Thursday 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.
