Jersey Shore officials are pleading with the public to avoid swimming in the ocean when no lifeguards are around, especially now with Hurricane Erin.

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.

Watch out for rip currents this weekend if you are getting in the water at the Jersey Shore or Delaware beaches. Even the best swimmers can be affected by dangerous rip currents.
