NORFOLK, Virginia — The Navy is moving people and ships ahead of Hurricane Florence, and the Air Force and Army are both flying advanced aircraft elsewhere as a safeguard. Some remaining Marines, meanwhile, are digging in their heels. Florence is headed for a region with some of the most well-known military bases in the country, including Camp Lejeune in North Carolina, Naval Station Norfolk in Virginia and the Marine Corps Recruit Depot on Parris Island in South Carolina. While thousands of Marines and their families have already left Camp Lejeune in Jacksonville, North Carolina, the commanding general said Tuesday that anyone remaining at the base would have food, water and protection despite being in the projected path of the storm. “Since 1941, this base and its Marines have been postured to deal with crises at home and abroad and Hurricane Florence is no exception,” said a message from Brig.
