Hurricane Irma brought flooding to Sint Maarten and Saint Martin, the Dutch and French sides of the same island, as well as Dutch island of Saba on Wednesday.
Footage of the storm's impact is included below:
Hurricane Irma has caused torn off rooftops and knocked out all electricity on the French islands of Saint Martin and Saint Barthelemy, and France has requisitioned planes and sent in emergency food and water rations.
The regional authority for Guadeloupe and neighboring islands said in a statement Wednesday that the fire station in Saint Barthelemy is under more than 3 feet of water and no rescue vehicles can move.
It said the government headquarters Saint Martin is partially destroyed and the island is in a total blackout.
Electricity is also partially down on the larger island of Guadeloupe, where the threat receded despite danger of heavy flooding.
French minister for overseas territories Annick Girardin expressed fear "for a certain number of our compatriots who unfortunately didn't want to listen to the protection measures and go to more secure sites."
She added: "We're preparing for the worst."
