The poor conditions, spawned by Hurricane Igor, spurred the National Weather Service to issue a high surf advisory, which was to remain in effect through midnight Monday. It also warned that increasing swells could cause beach erosion in many areas.
Forecasters say the storm was kicking up swells that ranged from 4 to 8 feet, with the highest amounts in southern areas. The swells were expected to keep building as the day progressed and continue through Monday.
Officials said swimmers who chose to enter the rough conditions should stay in areas where lifeguards were stationed and not swim alone.
