OCRACOKE, N.C. (AP) — A weakened Hurricane Dorian flooded homes on North Carolina’s Outer Banks on Friday with a ferocity that took even storm-hardened residents by surprise, forcing people to retreat to their attics. Hundreds were feared trapped by high water.

Sheriff’s officials sent medics and other rescuers to Ocracoke Island — accessible only by boat or air — to reach those who did not evacuate the 200-mile (320-kilometer) ribbon of low-lying islands that stick out from the Eastern Seaboard like the side-view mirror on a car.

“There is significant concern about hundreds of people trapped on Ocracoke Island,” Gov. Roy Cooper said. “There are rescue teams ready as soon as they can get in.”
