THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THUNDERSTORMS: INSTABILITY IS INCREASING AHEAD OF A STRONG
SHORTWAVE TROUGH AND SURFACE COLD FRONT WHICH WILL SWEEP ACROSS
MAINLAND SOUTH FLORIDA LATE THIS AFTERNOON AND EVENING.
AS A RESULT, THUNDERSTORMS ARE EXPECTED TO DEVELOP THROUGHOUT THE
AFTERNOON. A FEW THUNDERSTORMS COULD BECOME SEVERE PRODUCING
DAMAGING WINDS, LARGE HAIL, AND POSSIBLY EVEN A TORNADO.

TORNADOES: SUFFICIENT WIND SHEAR EXISTS ACROSS THE AREA TO RESULT
IN A SLIGHT RISK OF TORNADOES THIS AFTERNOON, MAINLY ACROSS THE
LAKE OKEECHOBEE REGION TO PALM BEACH COUNTY. HOWEVER, THERE IS A
SLIGHT RISK EVEN FURTHER SOUTHWARD DOWN THE BROWARD AND MIAMI-DADE
COUNTY COAST DUE TO THE POSSIBILITY OF A MORE SOUTHERLY OR
SOUTHEASTERLY SURFACE WIND FLOW BEING MAINTAINED ACROSS THIS AREA.

WATERSPOUTS: THUNDERSTORMS OVER THE LOCAL WATERS THIS AFTERNOON WILL
BE CAPABLE OF PRODUCING WATERSPOUTS.

WIND: A FEW THUNDERSTORMS COULD PRODUCE DAMAGING WINDS OF 50 TO 60
MPH THIS AFTERNOON.

HAIL: HAIL OF DIME TO QUARTER SIZE IS POSSIBLE IN A FEW THUNDERSTORMS
THIS AFTERNOON.

WAVES: AS A COLD FRONT MOVES THROUGH THE REGION LATE THIS
AFTERNOON AND EVENING, WINDS WILL SHIFT TO THE NORTHWEST AND
INCREASE TO 15 TO 20 KNOTS OVERNIGHT. AS A RESULT, SEAS IN THE
GULF STREAM WILL APPROACH 7 FEET BY SATURDAY MORNING.

RIP CURRENTS: SOUTHWESTERLY WINDS AROUND 15 MPH WILL CREATE A
SLIGHT RISK FOR RIP CURRENT FORMATION ALONG THE GULF COAST BEACHES
THIS AFTERNOON. SWIMMERS ARE ENCOURAGED TO FOLLOW WARNINGS OF
LOCAL LIFEGUARDS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

NORTHERLY WINDS OF AROUND 15 KNOTS WILL ALLOW SEAS IN THE GULF
STREAM TO BUILD TO 8 TO 10 FEET SATURDAY NIGHT THROUGH
SUNDAY...BEFORE SLOWLY SUBSIDING THEREAFTER AS WINDS SHIFT TO A
MORE NORTHEASTERLY DIRECTION.

THE THREAT FOR RIP CURRENTS WILL INCREASE ACROSS THE ATLANTIC
COAST BEACHES EARLY NEXT WEEK AS A MODERATE TO STRONG EASTERLY
FLOW DEVELOPS.

SEVERE WEATHER TO THE MIAMI WEATHER FORECAST OFFICE BY CALLING
