The tropical wave associated with the remnants of Tropical Depression Kirk has regenerated into Tropical Storm Kirk. Rainfall accumulations of at least two to four inches (50 to 100 mm) are possible between Thursday and Friday morning.

Kirk has made a comeback as a tropical storm and is heading for the northern Windward Islands, triggering a tropical storm warning for Barbados, St Lucia, Dominica, Martinique, Guadeloupe and a tropical storm watch for St Vincent and the Grenadines.

A hurricane is a tropical cyclone that has maximum sustained surface winds of 74 miles per hour or greater. Forecasters said it is expected to strengthen but doesn't pose an immediate threat to land.

Wind speeds will start to increase across Barbados later tonight, with sustained surface winds of 25 to 35 miles per hour (40 to 55 km/h) with gusts to storm force expected to spread across the island tomorrow.

On Tuesday, Tropical Storm Rosa formed off the Pacific Coast. There may be thunderstorms in a few areas today and street/flash flooding and gusty winds are still possible in the event of heavy downpours.

Wind: Tropical storm conditions are expected to first reach the warning area by Thursday afternoon, making outside preparations hard or risky.
