Tropical Storm Don continues its approach on the Windward Islands, after forming in the Atlantic Ocean on Monday.
Tropical Storm Don has sustained winds of 50 mph and is moving west going nearly 18 mph, as of the 5 a.m., Tuesday advisory of the U.S. National Hurricane Center. The storm is expected to gain forward speed through Wednesday.
Tropical Storm warnings are in effect for Grenada, and St. Vincent and the Grenadines, as Don moves toward the eastern Caribbean. Barbados, St. Lucia and Bonaire were under a tropical storm watch as of the 5 a.m. advisory.
The storm is expected to move across the the Windward Islands Tuesday night and continue westward across the Southeastern Caribbean Sea.

Because Don is “compact,” its intensity can change significantly, Hurricane Center forecasters said. Don is expected to strengthen overnight, but weaken once it moves over the Caribbean Sea.
There was no discussion in the Tuesday 5 a.m. advisory of the storm threatening the continental U.S. in the future. Forecasters expect the storm to dissipate within 72 hours.
Forecasters are also keeping an eye out for a tropical wave over the central tropical Atlantic that is several hundred miles west-southwest of the Cabo Verde Islands. The wave has been given a 30 percent chance of turning into a tropical cyclone within 48 hours, as of the 2 a.m. advisory.
Gradual development of the system is possible through the midweek as it continues to move west-northwest between 10 and 15 mph. Its chances of turning into a cycle stand at 40 percent within five days.
