At 500 PM AST (2100 UTC), the center of Tropical Storm Kirk was located near latitude 14.2 North, longitude 60.2 West. Kirk is moving toward the west-northwest near 14 mph (22 km/h). A west-northwestward to westward motion is expected over the next couple of days. On the forecast track, the center of Kirk will move across the Lesser Antilles within the Tropical Storm Warning area this evening.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is expected before Kirk moves through the Lesser Antilles. Gradual weakening is anticipated during the next couple of days while the system moves over the eastern Caribbean Sea. Kirk is forecast to become a tropical depression Friday night, and degenerate into a trough of low pressure by Sunday.
Tropical-storm-force winds extend outward up to 140 miles (220 km) primarily to the east of the center.
The estimated minimum central pressure is 1000 mb (29.53 inches).
