...HIGH RISK OF RIP CURRENTS TODAY...

THERE IS A HIGH RISK OF RIP CURRENTS TODAY, WHICH IMPLIES THAT
WIND AND/OR WAVE CONDITIONS SUPPORT THE DEVELOPMENT OF VERY STRONG
RIP CURRENTS. THESE RIP CURRENTS WILL BE LIFE THREATENING TO
ANYONE WHO ENTERS THE SURF. STRONG RIP CURRENTS CAN MOVE YOU AWAY
FROM THE SHORELINE VERY QUICKLY.

PLEASE CHECK WITH LIFEGUARDS BEFORE ENTERING THE WATER, AND DO NOT
SWIM IN UNSUPERVISED AREAS.

RIP CURRENTS ARE STRONG, NARROW CHANNELS OF WATER THAT FLOW OUT TO
SEA. IF YOU BECOME CAUGHT IN A RIP CURRENT, STAY CALM AND DO NOT
FIGHT IT. SWIM PARALLEL TO THE SHORE UNTIL YOU BREAK FREE OF THE
CURRENT. THEN SWIM AT AN ANGLE, AWAY FROM THE CURRENT, TOWARD THE
SHORE. IF YOU ARE UNABLE TO ESCAPE BY SWIMMING, FLOAT OR TREAD
WATER. WHEN THE CURRENT WEAKENS, SWIM AT AN ANGLE AWAY FROM THE
CURRENT TOWARD THE SHORE. IF AT ANY TIME YOU FEEL YOU WILL NOT BE
ABLE TO REACH THE SHORE, DRAW ATTENTION TO YOURSELF BY CALLING OR
WAVING FOR HELP.
