* LOW RISK OF RIP CURRENTS - STRONG CURRENTS CAN STILL OCCUR NEAR
JETTIES AND REEF CHANNELS. ALWAYS HAVE A FLOTATION DEVICE WITH YOU
IN THE WATER.
MODERATE RISK OF RIP CURRENTS - WAVE CONDITIONS SUPPORT STRONGER OR
MORE FREQUENT RIP CURRENTS. ALWAYS HAVE A FLOTATION DEVICE WITH YOU
IN THE WATER.
HIGH RISK OF RIP CURRENTS - LARGE WAVES WILL PRODUCE STRONG RIP
CURRENTS, ESPECIALLY ALONG NARROW REEFS AND BEACHES. RIP CURRENTS
WILL BE LIFE THREATENING. IF CAUGHT IN A RIP CURRENT, SWIM PARALLEL
TO THE BEACH RATHER THAN AGAINST THE CURRENT.
