Rip currents can sweep even the best swimmers away from shore into deeper water. * ADDITIONAL DETAILS...A large northeast swell combined with a north secondary swell produced by a strong mid-latitude frontal system and a nearby shear line will produce hazardous surf along north facing reefs and a high risk of rip currents along north and east facing reefs.

Rip currents will be life threatening. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
