Kirk is moving toward the west-northwest near 15 mph (24 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.

Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center.
The minimum central pressure estimated from Air Force Hurricane Hunter observations is 999 mb (29.50 inches).
