Hurricane Irma, the most powerful Atlantic Ocean hurricane in recorded history, made landfall early Wednesday in the Caribbean islands.

At the far northeastern edge of the Caribbean, authorities on the Leeward Islands of Antigua and Barbuda cut power and urged residents to shelter indoors as they braced for Hurricane Irma’s first contact with land early Wednesday. Officials warned people to seek protection from Irma’s “onslaught” in a statement that closed with: “May God protect us all.”
