Dorian strengthened to a Category 1 hurricane Wednesday, lashing the U.S. and British Virgin Islands with heavy rain.
The entire British Virgin Islands lost power at the height of the storm, according to the British Islands Department of Disaster Management. Partial power was restored to one-third of the island by 9 p.m. Almost 40,000 customers were without power on the U.S. Virgin Islands at about 5 p.m. on Wednesday, but that number slowly eased throughout the night.
