Hurricane Dorian has been gaining strengthen as it hurtles towards US mainland after sparking blackouts and flooding across the Virgin Islands.
The storm caused limited damage in the northern Caribbean as it left the region on Wednesday night, but experts said it could still grow into a dangerous Category 3 storm.
Power outages and flooding were reported across the US Virgin Islands, the British Virgin Islands and the Puerto Rican islands of Vieques and Culebra after Dorian hit St Thomas.
"We're happy because there are no damages to report," Culebra Mayor William Solis said after the Category 1 storm swept through the region.
Meanwhile, Dorian caused an island-wide blackout in St Thomas and St John in the US Virgin Islands, and scattered power outages in St Croix, government spokesman Richard Motta said.
In addition, the storm downed trees and at least one electric post in St Thomas, he said, adding that there were no reports of major flooding.
"We are grateful that it wasn't a stronger storm," he said.
There were no immediate reports of damage in the British Virgin Islands, where Governor Augustus Jaspert said crews were clearing roads and inspecting infrastructure
Dorian had prompted US President Donald Trump to declare a state of emergency on Tuesday night and order federal assistance for local authorities.
At 11pm (4am UK time), Dorian was centred about 90 miles north of San Juan, the capital of Puerto Rico.
The US National Hurricane Centre said its maximum sustained winds had increased to 85 mph as the storm moved north-west at 13mph.
The organisation said the storm could grow into a Category 3 as it heads in the general direction of Florida.
Dennis Feltgen, a Hurricane Centre meteorologist in Miami, said Dorian could land anywhere from South Florida to South Carolina on Sunday or Monday.
"This will be a large storm approaching the Southeast," he said.
