EAST CENTRAL FLORIDA HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE MELBOURNE FL
1135 AM EDT FRI MAY 7 1999

...THUNDERSTORMS LIKELY THIS AFTERNOON AND EVENING...SEVERE STORMS
POSSIBLE...

THE COMBINATION OF AN UNSTABLE ATMOSPHERE WITH SEA BREEZE BOUNDARIES
ALONG BOTH COASTS AND AN UPPER LEVEL DISTURBANCE WILL RESULT
SCATTERED THUNDERSTORMS DEVELOPING THIS AFTERNOON AND EVENING.

WITH SOUTH TO SOUTHWEST WINDS THROUGH LOWER LEVELS OF THE
ATMOSPHERE...THE EAST COAST SEA BREEZE WILL DEVELOP AND ONLY REACH
INLAND TO NEAR THE ST. JOHNS RIVER THROUGH THE MID AFTERNOON. A FEW
SHOWERS AND STORMS WILL DEVELOP ALONG THIS BOUNDARY THROUGH THE MID
AFTERNOON. STORM COVERAGE AND INTENSITY WILL INCREASE THROUGH THE
LATE AFTERNOON AND EVENING AS THE WEST COAST SEA BREEZE PROGRESSES
ACROSS THE STATE AND COLLIDES WITH THE EAST COAST BOUNDARY. STORMS
WILL EVENTUALLY MOVE NORTHEAST OVER THE COASTAL WATERS THIS EVENING.

SOME OF THE STORMS WILL BE CAPABLE OF PRODUCING LARGE HAIL...
DAMAGING WIND GUSTS...AND FREQUENT TO EXCESSIVE LIGHTNING...OVER
BOTH LAND AND WATER. A FEW SPOTS COULD PICK UP IN EXCESS OF TWO
INCHES OF RAINFALL IN A VERY SHORT PERIOD OF TIME...WHICH MAY CAUSE
PONDING OF WATER ON ROADWAYS AND OTHER LOW LYING AREAS.
ADDITIONALLY...ISOLATED STRONGER STORMS COULD PRODUCE A BRIEF
TORNADO OR WATERSPOUT.

IF SKIES THREATEN...HEAD INDOORS TO SAFETY BEFORE THE STORM REACHES
YOUR LOCATION. IF OUT ON THE INTRACOASTAL OR NEAR SHORE WATERS...
KEEP AN EYE OUT FOR APPROACHING STORMS AND SEEK SAFE HARBOR BEFORE
STORMS REACH YOU. SKYWARN SPOTTER NETWORKS ARE REQUESTED TO SELF
ACTIVATE IF A WATCH OR WARNING IS ISSUED FOR THEIR COUNTY.
