Area forecast discussion, Jun 10, 9:57 PM EDT, 1 hour 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
957 PM EDT SUN JUN 10 2012

.DISCUSSION...
COLLISION OF TWO SEPARATE LINES OF STRONG STORMS HAS PRODUCED A
LARGE THUNDERSTORM COMPLEX THAT IS SHIFTING EAST OF ORLANDO TOWARD
BREVARD COUNTY. DID A QUICK UPDATE TO THE ZONES TO INCREASE RAIN
CHANCES FOR BREVARD COUNTY DUE TO THIS ACTIVITY. STRONG TO
MARGINALLY SEVERE WIND GUSTS AND COIN SIZED HAIL COULD STILL BE
POSSIBLE WITH STORMS THROUGH LATE EVENING. CONVECTION SHOULD WIND
DOWN SOON AFTER MIDNIGHT WITH RAIN CHANCES ENDING. DEBRIS CLOUD
COVER WILL ALSO EVENTUALLY DISSIPATE...BECOMING PARTLY CLOUDY LATE
TONIGHT. COOLING FROM THE HEAVY RAIN HAS ALREADY DROPPED TEMPS TO
NEAR THEIR EXPECTED LOW VALUES SO LITTLE CHANGE IN TEMPS WILL
OCCUR OVERNIGHT.

&&

.AVIATION...STRONG STORMS HEADING EAST OF MCO WILL BRING TEMPO IFR
CONDS AND GUSTY WINDS INTO BREVARD COUNTY...SOUTHWARD TO MLB.
ADDITIONAL SHOWERS/STORMS WILL PRODUCE TEMPO IFR/MVFR CONDS INTO
LATE EVENING FROM KLEE TO KDAB SOUTHWARD TO KMCO MAINLY THROUGH
04Z. CONVECTION SHOULD THEN WIND DOWN SOON AFTER MIDNIGHT WITH
PREDOMINANT VFR CONDS EXPECTED INTO TOMORROW MORNING.

&&

.MARINE...STORMS WILL PUSH OFFSHORE OF BREVARD COUNTY BEFORE
MIDNIGHT...OTHERWISE FAVORABLE BOATING CONDS EXPECTED WITH SE
WINDS AROUND 10-15 KTS AND SEAS 2-4 FT.

&&

.MLB WATCHES/WARNINGS/ADVISORIES...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
THE EAST AND WEST COAST SEA BREEZES ARE EXPECTED TO COLLIDE OVER
AN AREA FROM NORTHWEST VOLUSIA COUNTY TO WESTERN ORANGE...LAKE
KISSIMMEE ...THEN ALONG THE KISSIMMEE RIVER TO LAKE OKEECHOBEE.
STORM COVERAGE OVER THE WESTERN INTERIOR WILL INCREASE FROM LATE
AFTERNOON INTO THE EARLY EVENING AS THE SEA BREEZE BOUNDARIES
COLLIDE. THE PRIMARY WEATHER HAZARDS WILL BE WIND GUSTS TO 45
MPH...CLOUD TO GROUND LIGHTNING STRIKES AND LOCALLY HEAVY RAIN DUE
TO SLOW ERRATIC STORM MOTION.

.FLOOD IMPACT...
VERY SLOW STORM MOTION WILL MEAN THAT STORMS WILL REMAIN OVER A
SINGLE LOCATION FOR A LONGER PERIOD OF TIME. LOCAL RAINFALL AMOUNTS
OF 1 TO 2 INCHES ARE POSSIBLE...WHICH WOULD PRODUCE VERY SHORT
LIVED FLOODING OF SOME ROADS...LOW SPOTS UNDER BRIDGES AND OVERPASSES
AND IN POOR DRAINAGE AREAS. ANY FLOODING SHOULD QUICKLY DISSIPATE
AS THE DRAINAGE SYSTEMS CATCH UP TO THE BRIEF EXCESSIVE RAINFALL
AMOUNTS.

.MARINE THUNDERSTORM GUST IMPACT...
EARLY AFTERNOON SHOWERS AND STORMS AT THE COAST SHIFT TO THE INLAND
LAKES AND WATERWAYS MID AND LATE AFTERNOON AND INTO THE EARLY
EVENING AS THE SEA BREEZE PUSHES WESTWARD. STORM MOTION WILL BE
ERRATIC...WITH A FEW STORMS DRIFTING BACK TO THE EAST LATE
AFTERNOON AND EARLY EVENING. A FEW STRONG STORMS WILL BE CAPABLE
OF PRODUCING GUSTY WINDS TO 35 KNOTS AND CLOUD TO WATER LIGHTNING
STRIKES.

.RIP CURRENT IMPACT...
OCEAN CONDITIONS WILL PRODUCE AN ELEVATED RISK FOR RIP CURRENTS AT
EAST CENTRAL FLORIDA BEACHES TODAY...CHECK WITH LIFEGUARDS ABOUT
OCEAN HAZARDS WHEN ARRIVING AT THE BEACH. SWIM ONLY WHERE THERE IS
A LIFEGUARD ON DUTY.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
SCATTERED SHOWERS AND STORMS ARE EXPECTED EACH AFTERNOON AS THE
EAST COAST SEA BREEZE DEVELOPS AND MOVES INLAND. STORM CHANCES WILL
INCREASE LATE IN THE WEEK AS ANOTHER WEAK FRONT MOVES INTO NORTH
FLORIDA.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
