Atlantic City, Wildwood, Margate, and Ocean City are among the towns that have banned ocean swimming as the hurricane moves north.

The girl’s sister, Sameeha Sultana, 13, was found unresponsive about an hour later at 7th Avenue, a block north. Rescue crews and the U.S. Coast Guard pulled her out of the water, and CPR was performed. She was taken to Jersey Shore University Medical Center, where she was pronounced dead.
