LONG BEACH - A warm day at the beach turned frightening for three swimmers who had to be rescued by lifeguards in Long Beach today.

City Manager Charles Theofan says one of the three incidents was serious. He says the swimmer was out too far and couldn't get back to the shore.

City officials have put together a PSA detailing the dangers of swimming when the beach is closed and there are no lifeguards on duty.

They say today was a stark reminder of last year when a 12-year-old girl from Harlem drowned as rescuers desperately tried to save her.
