North Carolina's Outer Banks are bracing for the effects of Hurricane Maria, even though the storm is expected to pass the state at least 150 miles (240 kilometers) offshore.

Schools were closed Tuesday in all of Dare County because of expected tropical storm conditions. Dare County includes much of the Outer Banks, as well as some inland areas along Pamlico Sound.

The National Weather Service in Morehead City, North Carolina, said significant beach erosion is expected north of Cape Lookout. Storm surge of between 2 feet (0.6 meters) and four feet (1 meter) is expected, mostly north of Cape Hatteras.

Officials ordered visitors to leave both Ocracoke and Hatteras islands ahead of the storm.

They warned dangerous rip currents were possible in the ocean for the rest of the week.
