FIRST ALERT: Tropical Storm Matthew forms in the Atlantic

(RNN) – A storm system in the Atlantic became the 13th named storm of the season, according to the National Hurricane Center.

Tropical Storm Matthew is moving west at 21 mph with maximum sustained winds of 60 mph. The storm is located about  35 miles east of St. Lucia and St. Vincent.

A tropical storm warning was issued for Barbados, Dominica, St. Vincent, the Grenadine Islands, St. Lucia and the French Islands of Guadeloupe and Martinique.

The National Hurricane Center advises people in the Lesser Antilles to keep their eyes on Matthew.

Forecasters expect the storm to continue on this path and say tropical-storm-force winds and heavy rains will spread across the southern Leeward Islands and northern Windward Islands, which may produce landslides and mud slides.

Tropical Storm Matthew could strengthen into a hurricane by Friday.

If the storm turns northward, forecasters say it may threaten the U.S. Gulf Coast and Atlantic Seaboard next week.

The last hurricane to hit the U.S. was Hurricane Hermine, which caused flooding, property damage and at least three deaths along the East Coast, as both a hurricane and a tropical storm.

The southeastern U.S. also saw heavy rain from Tropical Storm Julia, the 10th named storm of the season.

Tropical Storms Ulika and Roslyn are continuing to turn in the Pacific. There are no watches or warnings associated with either one.
