Kirk will start its weakening phase during the next couple of days but is forecast to move across the Lesser Antilles and into the Caribbean Sea as a tropical storm.
Tropical-storm-force winds extend outward up to 220 km (140 miles), mostly north and east of the center. The estimated minimum central pressure is 1002 hPa.
Kirk is expected to produce total rainfall of 101 - 152 mm (4 to 6 inches) across the northern Windward and the southern Leeward Islands with isolated maximum totals up to 254 mm (10 inches) across Martinique and Dominica.
These rains may produce life-threatening flash floods and mudslides.
