One of two disturbances in the Atlantic became Tropical Storm Don shortly before 5 p.m. Monday, according to the National Hurricane Center.
On Monday evening, Don was about 525 miles east-southeast of Barbados, according to the National Hurricane Center. The storm is expected to reach the Lesser Antilles late Tuesday or early Wednesday.
A disturbance also is stirring about 900 miles west-southwest of the Cabo Verde Islands, the center said Monday.
This disturbance is expected to track west-northwest or northwest, according to the hurricane center.
The disturbance’s path is still uncertain, according to Accuweather. If the system grows to more than “a batch of showers and thunderstorms,” it could curve north and approach the Leeward Islands.
The center has given this disturbance a 20 percent chance of developing into a tropical depression in the next 48 hours and a 30 percent chance of developing in the next five days.
