Hurricane Fiona strengthened to a powerful Category 4 storm on Wednesday as it headed toward Bermuda after carving a destructive path through the Dominican Republic and Puerto Rico, where the storm left most people without power and up to eight dead.
After making landfall in Puerto Rico on Sunday, Fiona caused devastating flooding and landslides on the island. Over the next two days, the storm gathered steam as it barreled into the Dominican Republic and the Turks and Caicos Islands.
