ST. JOHN’S, Antigua (AP) — The most powerful Atlantic Ocean hurricane in recorded history bore down on the islands of the northeast Caribbean on Tuesday night, following a path predicted to then rake Puerto Rico, the Dominican Republic, Haiti and Cuba before possibly heading for Florida over the weekend. 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.
