THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Numerous showers and embedded lightning storms are forecast to move
from west to east across central Florida this afternoon. Abundant
moisture and instability will favor development of storms across
the entire area, especially from the Orlando area southward and
toward Brevard County and the Treasure Coast through late
afternoon.

Storms moving toward the east around 15 to 20 mph will be capable
of producing periods of heavy rain up to two inches per hour,
gusty winds up to 40 mph, and frequent lightning strikes. Always
move indoors when thunder is heard or lightning observed. Motorists
should always slow down and use low beam headlights in heavier
showers.

.MARINE THUNDERSTORM GUST IMPACT...
Numerous showers and storms will develop and move eastward around
15 knots across inland lakes and toward the east coast and
offshore this afternoon. Any stronger storms will have the
potential to produce wind gusts in excess of 35 knots, especially
as storms push offshore the east central Florida coast. Boaters
should ensure they can make safe harbour if venturing over the
open Atlantic or larger inland lakes.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Higher rain chances, along with the possibility of localized
minor flooding will be present daily through most of next week.
Showers and thunderstorms are expected with the associated threats
of lighting and brief gusty winds mainly in the afternoon.

.SPOTTER INFORMATION STATEMENT...
Spotters are requested to monitor the weather and self activate
if needed.
