...MODERATE RISK OF RIP CURRENTS TODAY...

THERE IS A MODERATE RISK OF RIP CURRENTS TODAY, WHICH IMPLIES THAT
INDIVIDUALS PLANNING TO ENTER THE SURF SHOULD CHECK WITH LOCAL
BEACH PATROLS FIRST. BE SURE TO SWIM WITHIN SIGHT OF A LIFEGUARD,
AND NEVER SWIM ALONE OR AT NIGHT.

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.
