Capt. Kent Buckson said Saturday afternoon that "huge waves" have left beach-goers with a broken leg, a neck injury, several dislocations, as well as cuts, scrapes and abrasions.
Buckson says waves are six to seven feet high after the storm, compared to a usual height of two to three feet.
He called it a "a bit of a dangerous day" at the beach and said his team has rescued several people from the water. There have been no fatalities, however, Buckson said.
Lifeguards at Rehoboth Beach kept people out of the water Friday, but the beaches were open Saturday.
