Tropical storm warnings and watches have been posted for the eastern Caribbean islands.

The fourth named storm of the 2019 hurricane season continued to churn toward the eastern Caribbean on Sunday.

Tropical storm warnings have been issued for Barbados and St. Vincent and the Grenadines. A tropical storm watch has been issued for St. Lucia.

The 11 a.m. advisory from the National Hurricane Center said maximum sustained winds are near 40 mph with higher gusts. Hurricane experts expect some strengthening during the next 48 hours.

Dorian could be near hurricane strength by Tuesday over the warm eastern Caribbean Sea, the NHC said.

Dorian is moving toward the west near 14 mph and speed and path should

continue through Sunday. A turn toward the west-northwest is expected on Monday and continue through Tuesday night. By late Monday, Dorian’s center is expected to Windward Islands.

The storm would stay to the southwest of Puerto Rico before making landfall in the Dominican Republic on Friday.

Tropical Storm Dorian grew from the fifth tropical depression of the 2019 season, which had formed early Saturday.

This weekend, however, South Florida residents were spared the brunt of a tropical disturbance that brewed late last week over the Bahamas. That storm drifted northeast, taking heavy rains and wind with it.

That said, Palm Beach County forecasters are calling for mid-afternoon thunderstorms in Palm Beach County, with a high temperature of 89.

Dorian’s trek is expected to follow a north-northwest direction through the remainder of this week. That path would have it cross the Lesser Antilles between Monday and Tuesday.
