A tropical storm watch has been issued for Barbados. The system is expected to reach the Lesser Antilles by Tuesday.

8 A.M. SUNDAY UPDATE: Tropical Storm Dorian is continuing its westerly journey over the western tropical Atlantic about 515 miles east-southeast of Barbados. Maximum sustained winds are 40 mph as the storm moves to the west at 13 mph.


A Tropical Storm Watch is in effect for Barbados.


SATURDAY’ STORY:


The fourth named storm of the Atlantic hurricane season formed Saturday afternoon, with maximum sustained winds of 40 mph, the National Hurricane Center said.


Tropical Storm Dorian grew from the fifth tropical depression of the 2019 season, which had formed early Saturday, the hurricane center said in its 5 p.m. update.


At that time, the storm was about 725 miles east to southeast of Barbardos, the easternmost island in the Lesser Antilles, and was moving west at 12 mph with maximum sustained winds of 40 mph.


It was about 1,400 miles from South Florida, and not expected to pass near Puerto Rico, Haiti or the Dominican Republic before Thursday.


Dorian could be near hurricane strength Tuesday as it approaches islands such as Martinique and St. Lucia in the central Lesser Antilles, the hurricane center said.

Forecasters expect the depression to turn to the west-northwest Sunday and continue on that path through Tuesday.


Tropical storm and hurricane watches may be needed for portions of the Lesser Antilles as early as Sunday, the hurricane center said.


A moderate to strong vertical wind shear that has hindered the system’s development during the past several days is expected to diminish significantly during the next 12 hours, the hurricane center said.


Word of Dorian came as a disturbance passed through Florida, bringing showers and thunderstorms from the Lake Okeechobee area eastward to the northwestern Bahamas.


The National Weather Service said showers and thunderstorms are likely to continue through Sunday evening across South Florida, with high temperatures in the 90s.
