The expected path of a disturbance in the Atlantic Ocean behind Hurricane Erin—with the potential to develop into a cyclone—has shifted since Tuesday, according to data from the National Hurricane Center (NHC).

Hurricane Erin forced tourists to cut their vacations short on North Carolina’s Outer Banks even though the monster storm is expected to stay offshore after lashing part of the Caribbean with rain and wind on Monday.

Hurricane Erin strengthened 85 mph in 24 hours to a 160 mph Category 5 hurricane putting in fourth place for rapidly intensifying storms.

Much of North Carolina’s Outer Banks region is under a tropical storm watch with Hurricane Erin expected to skirt the area Wednesday through Thursday, according to the National Hurricane Center.
