The storm packed 40 mph (65 kmh) winds as it headed west at 13 mph early on Sunday morning. It was forecasted to be near central Lesser Antilles late on Monday or early Tuesday, the National Hurricane Center (NHC) said.
As of Sunday morning, Barbados was under a tropical storm watch. It was the only island under an advisory.
But the NHC said it was likely to issue additional watches for portions of the Windward and Leeward Islands on Sunday, noting that Puerto Rico and Hispaniola should monitor Dorian’s progress.
Dorian’s winds could weaken as it passes south of Puerto Rico and approaches Hispaniola.
Many Caribbean islands are likely to receive 2 to 4 inches (5 to 10 cm) of rain, but some part of the Lesser Antilles islands could get 6 inches, the NHC said.
