...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST
THURSDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH THURSDAY
AFTERNOON...
* WHAT...LARGE BREAKING WAVES OF 9 TO 11 FEET AND DANGEROUS RIP
CURRENTS EXPECTED.
* WHERE...ALONG WEST AND NORTH FACING REEFS.
* WHEN...UNTIL 4 PM CHST THURSDAY.
* IMPACTS...DANGEROUS SWIMMING AND SURFING CONDITIONS AND
LOCALIZED BEACH EROSION. RIP CURRENTS CAN SWEEP EVEN THE BEST
SWIMMERS AWAY FROM SHORE INTO DEEPER WATER.
* ADDITIONAL DETAILS...A STRONG MONSOON PATTERN CONTINUES TO
PRODUCE HAZARDOUS SURF AND A HIGH RISK OF RIP CURRENTS ALONG WEST
AND NORTH-FACING REEFS. AS INFLUENCE FROM TYPHOON DOLPHIN ON THE
MONSOON PATTERN DECREASES, INFLUENCE FROM TROPICAL STORM CHAN-HOM
AND OTHER DISTURBANCES WILL INCREASE. THIS WILL KEEP SURF
ELEVATED AND ABOVE HAZARDOUS CONDITIONS FOR WEST AND NORTH FACING
REEFS THROUGH MUCH OF THE COMING WEEK, AND SURF HAZARDS HAVE BEEN
EXTENDED THROUGH THURSDAY AFTERNOON. THE HIGH SURF ADVISORY AND
HIGH RIP CURRENT RISK MAY BE EXTENDED AGAIN NEXT WEEK AS THE
MONSOON PATTERN, AND ASSOCIATED WEST TO NORTHWEST SWELLS,
CONTINUE.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
RIP CURRENTS WILL BE LIFE THREATENING. INEXPERIENCED SWIMMERS
SHOULD REMAIN OUT OF THE WATER DUE TO DANGEROUS SURF CONDITIONS.
RIP CURRENTS WILL BE LIFE THREATENING. 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.
