An evacuation is underway on an island on North Carolina’s Outer Banks as Hurricane Maria moves north.

The Hyde County Sheriff’s office said the evacuation began at 5 a.m. Monday on Ocracoke Island. It’s not immediately clear how many residents and visitors are heeding the order to leave.

The National Hurricane Center issued a tropical storm warning from Cape Lookout to Duck on the Outer Banks. A tropical storm watch was in effect from Surf City to Cape Lookout and from Duck to the North Carolina-Virginia state line.

Hyde County commissioners ordered the evacuation on the island still suffering from the effects of Hurricane Jose.

A storm surge of 2 feet  to 4 feet  is possible. Up to 2 inches of rain could fall through Wednesday.
