...LARGE SWELLS FROM DISTANCE HURRICANE BILL WILL LEAD TO A HIGH
RISK FOR RIP CURRENTS TODAY...


LONG PERIOD OCEAN SWELLS ARRIVING AT EAST CENTRAL FLORIDA BEACHES
TODAY AND TONIGHT WILL BRING A HIGH RISK FOR RIP CURRENTS.

A RIP CURRENT IS A NARROW CHANNEL OF WATER FLOWING OUTWARD FROM
THE SURF ZONE WHICH CAN CARRY EVEN STRONG SWIMMERS INTO DEEP WATER
BEYOND THE SAND BAR. 

IF CAUGHT IN A RIP CURRENT...TRY TO REMAIN CALM AND SIGNAL FOR
HELP. SWIM PARALLEL TO THE COAST UNTIL OUT OF THE PULL OF THE
CURRENT AND THEN RETURN TO SHORE. DO NOT TRY TO SWIM DIRECTLY
BACK TO SHORE AGAINST THE CURRENT SINCE THIS IS USUALLY WHAT
CAUSES MOST RIP CURRENT DROWNINGS.
