...HIGH RISK OF RIP CURRENTS ALONG ATLANTIC BEACHES...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

RIP CURRENTS: EAST WINDS OF 15 TO 20 MPH WITH HIGHER GUSTS ARE
EXPECTED THROUGH THE PERIOD ALONG THE EAST COAST AND THIS WILL KEEP
A HIGH RISK OF RIP CURRENTS AT THE ATLANTIC BEACHES OF PALM BEACH,
BROWARD, AND MIAMI-DADE COUNTIES. WHEN THE RIP CURRENT RISK IS
HIGH, THE SURF IS DANGEROUS FOR ALL LEVELS OF SWIMMERS. EVEN THOSE
USING SURF OR BOOGIE BOARDS ARE URGED TO USE EXTREME CAUTION. RIP
CURRENTS ARE LIFE-THREATENING TO ANYONE ENTERING THE SURF.

A RIP CURRENT IS A 10 TO 30 YARD WIDE CHANNEL OF WATER THAT CAN
PULL EVEN A STRONG SWIMMER FROM NEAR OR INSIDE THE SAND BAR INTO
DEEPER WATER. DUE TO THE LIFE THREATENING DANGERS THAT THESE
STRONG CURRENTS OF WATER POSE...SWIMMING IS NOT ADVISED.

FIRES: RECENT FIRES ACROSS SECTIONS OF INLAND COLLIER COUNTY IN
COMBINATION WITH MODERATE EASTERLY WINDS MAY RESULT IN PATCHY
SMOKE AROUND THE NAPLES AREA MAINLY THIS MORNING AND AGAIN LATE
TONIGHT. RESIDENTS ARE STILL ADVISED TO REMAIN IN CONTACT WITH
LOCAL AUTHORITIES AND THE MEDIA IN CASE FIRES GROW OUT OF CONTROL
DUE TO THE INCREASE IN EASTERLY WINDS WHICH COULD BE A CONCERN FOR
POPULATED AREAS.

NO OTHER HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THE RISK OF RIP CURRENTS WILL REMAIN HIGH THROUGH AT LEAST MONDAY
OR TUESDAY AND MODERATE THROUGH AT LEAST THE MIDDLE OF THE WEEK AS
WINDS ARE EXPECTED TO SUBSIDE ON TUESDAY AND WEDNESDAY.

ALSO, RESIDENTS IN THE NAPLES AREA SHOULD STILL STAY INFORMED
ABOUT THE FIRE SITUATION UNTIL THE FIRES ARE FULLY CONTAINED. FOR
THE MOMENT THE THREAT IS EXPECTED TO CONTINUE TO DIMINISH OVER
THE NEXT FEW DAYS.

NO OTHER HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
