SHOWERS AND STORMS. WILL KEEP POPS NEAR 40 PCT FOR THE LATE WEEK
AND THE WEEKEND EXCEPT FOR THE IMMEDIATE TREASURE COAST AND

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
LOW LEVEL SOUTHWEST FLOW...DEEP MOISTURE AND DAYTIME HEATING WILL
GENERATE SCATTERED AFTERNOON SHOWERS AND LIGHTNING STORMS ALONG THE
EAST AND WEST COAST SEA BREEZE BOUNDARIES...WITH STORMS LINGERING
INTO THE EVENING HOURS NEAR THE EAST COAST. THE HIGHEST COVERAGE IS
EXPECTED FROM AROUND LAKE GEORGE TO SANFORD AND ORLANDO...SOUTH TO
LAKE OKEECHOBEE AND EAST TO THE SPACE AND TREASURE COASTS. AS STORMS
APPROACH THE EAST COAST AND INTERACT WITH THE EAST COAST SEA BREEZE
SOME STORMS MAY BECOME STRONG. THE MAIN HAZARDS FROM THE STRONGER
STORMS WILL BE FREQUENT LIGHTNING STRIKES... GUSTY WINDS AND LOCALLY
HEAVY RAIN. A BRIEF FUNNEL CLOUD MAY OCCUR AS THE STRONGER STORMS
APPROACH THE COAST AND ENCOUNTER THE EAST COAST SEA BREEZE. STORM
MOTION WILL BE NORTHEAST AT 10 MPH.

.FLOOD IMPACT...
SLOW MOVING STORMS WILL HAVE THE POTENTIAL TO PRODUCE 1 TO 3 INCHES
OF RAINFALL...WHICH MAY CAUSE PONDING OF WATER IN POORLY DRAINED
AREAS...ON ROADS AND IN LOW SPOTS.

.WATERSPOUT IMPACT...HIGH MOISTURE COUPLED WITH LIGHT SOUTHWEST
WINDS AND LOCAL BOUNDARIES WILL FAVOR THE FORMATION OF WATERSPOUTS
OVER THE INTRACOASTAL WATERWAY AND ATLANTIC WATERS NEAR THE COAST.

.MARINE THUNDERSTORM GUST IMPACT...
SCATTERED STORMS DURING THE AFTERNOON AND EVENING WILL MOVE NORTHEAST
AT 5 TO 10 KNOTS OVER THE MAINLAND AND CROSS THE COASTLINE. AS THE
STORMS APPROACH THE COAST...A FEW STORMS MAY PRODUCE WIND GUSTS OVER
34 KNOTS ALONG WITH FREQUENT LIGHTNING STRIKES AND TORRENTIAL
DOWNPOURS.

.RIP CURRENT IMPACT...
A SMALL LONG PERIOD SWELL WILL PRODUCE A LOW TO MODERATE RISK OF
RIP CURRENTS AT THE BEACHES TODAY. ALWAYS CHECK WITH THE LIFEGUARDS
OR THE BEACH PATROL ABOUT SURF CONDITIONS BEFORE ENTERING THE SURF.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
DEEP SOUTHWEST TO WEST FLOW IS FORECAST TO CONTINUE TRANSPORTING
THIS WILL KEEP SCATTERED AFTERNOON AND EVENING STORMS IN PLACE
ACROSS EAST CENTRAL FLORIDA INTO THE UPCOMING WEEKEND.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.
