 Ocean swimmers are being reminded about the dangers of rip currents. Lifeguards rescued nine people in Ocean City, New Jersey over the weekend after some swimmers were initially in distress and others who went to save them also got into trouble. It happened Saturday at the Ninth Street Beach. Lifeguards were called in to help four people who were struggling. Others who were nearby jumped in to help but became stuck themselves and called for help. Officials say rip currents carried all of them.
