400 AM EDT SUN JUL 19 2009

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
SCATTERED TO NUMEROUS SHOWERS AND LIGHTNING STORMS WILL STREAM
OFF THE GULF OF MEXICO AND ACROSS LAKE...VOLUSIA...SEMINOLE AND
ORANGE COUNTIES WITHIN A BAND OF DEEP MOISTURE. THE PRIMARY THREAT
FROM THESE STORMS THIS AFTERNOON WILL BE DANGEROUS CLOUD TO GROUND
LIGHTNING...GUSTY DOWNBURST WINDS UP TO 50 MPH AND SMALL HAIL AS
THEY MOVE EAST TO NORTHEAST AROUND 15 TO 20 MPH.

SURFACE HEATING AND COOLING TEMPERATURES ALOFT...WILL PRODUCE A
THREAT FOR ISOLATED SEVERE STORMS ALONG THE SPACE AND TREASURE
COASTS LATE THIS AFTERNOON. THE EAST COAST SEA BREEZE WILL LIKELY
DEVELOP THIS AFTERNOON FROM THE CAPE SOUTHWARD BUT A BIT QUICKER
ALONG THE TREASURE COAST. THIS SEA BREEZE BOUNDARY SHOULD BE THE
FOCUS FOR ISOLATED LATE AFTERNOON STORMS CAPABLE OF PRODUCING
DAMAGING DOWNBURST WINDS...COIN SIZE HAIL AND EVEN A BRIEF
TORNADO. FREQUENT TO EXCESSIVE LIGHTNING STRIKES WILL ACCOMPANY
THE STRONGER STORMS. THE BEST CHANCE FOR SUCH STORMS WILL OCCUR
BETWEEN 4 AND 8 PM. INDIVIDUAL CELL MOTION WILL BE TOWARD THE EAST
AT 10 TO 15 MPH.

PLAN AHEAD FOR THE ONSET OF LIGHTNING BY IDENTIFYING A CLOSE AND
SECURE SHELTER THAT YOU CAN QUICKLY MOVE TO IF A STORM APPROACHES
WHILE OUTSIDE.

...FLOOD IMPACT...
BANDS OF MODERATE TO HEAVY RAIN MOVING OFF THE GULF OF MEXICO MAY
AFFECT NORTH LAKE AND VOLUSIA COUNTIES TODAY WITH ACCUMULATIONS OF
ONE TO TWO INCHES. IN ADDITION...LOCALLY VERY HEAVY RAIN FROM
STRONG STORMS LATE THIS AFTERNOON ALONG PORTIONS OF THE SPACE AND
TREASURE COASTS WILL HAVE THE POTENTIAL TO PRODUCE 2 TO 3 INCHES
OF RAIN IN A SHORT PERIOD OF TIME...CAUSING TEMPORARY FLOODING OF
SOME ROADS AND LOW LYING AREAS.

...RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL PRODUCE AN ELEVATED THREAT FOR
RIP CURRENTS AT THE BEACHES OF EAST CENTRAL FLORIDA TODAY. ALWAYS
SWIM WITHIN SIGHT OF A LIFEGUARD.

...MARINE THUNDERSTORM GUST IMPACT...
SCATTERED TO NUMEROUS LIGHTNING STORMS WILL MOVE QUICKLY TOWARD
THE EAST TO NORTHEAST AROUND 15 TO 20 MPH OVER NORTHERN EAST
CENTRAL FLORIDA AND OFFSHORE OF THE VOLUSIA COUNTY COASTLINE THIS
AFTERNOON. ADDITIONAL STORMS ARE EXPECTED TO DEVELOP ALONG THE
EAST COAST SEA BREEZE AND MOVE EAST TO NORTHEAST AROUND 10 TO 15 MPH
LATE THIS AFTERNOON FROM THE CAPE SOUTHWARD. THE SEA BREEZE WILL
MAKE A BIT MORE INLAND PENETRATION THAN SATURDAY...THOUGH A FEW
STORMS MAY STILL DEVELOP OVER THE INTRACOASTAL WATERS. BOATERS
SHOULD ANTICIPATE MARINE WARNINGS AS STORMS WILL BE CAPABLE OF
WIND GUSTS 35 KNOTS OR HIGHER AND FREQUENT TO EXCESSIVE LIGHTNING.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
AN UPPER LEVEL TROUGH WEST OF THE AREA AND COLD MID LEVEL
TEMPERATURES WILL BRING A CHANCE OF STRONG TO POSSIBLY SEVERE
STORMS MONDAY AFTERNOON. HIGH MOISTURE LEVELS WILL ALLOW SCATTERED
STORMS THROUGH MID WEEK AND THEN A SLIGHTLY LOWER COVERAGE OF
STORMS IS EXPECTED TO END THE WORK WEEK AS SOME DRIER AIR MOVES
OVER THE NORTHERN HALF OF THE STATE.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE
IF NEEDED.
