THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
A prevailing southwest wind flow will favor the central and
eastern peninsula for numerous showers and thunderstorms along
and ahead of the west coast sea breeze.

Activity will move east to northeast near 20 mph today, first
reaching Lake County by midday. Storms will reach the Interstate 4
corridor during the early to mid afternoon, and reach the east
coast by mid to late afternoon. Storms will move offshore or end
by around sunset.

Today`s storms will be capable of producing dangerous cloud to
ground lightning, torrential downpours, and wind gusts of 35 to
40 mph. Move indoors to safety at the first sign of threatening
skies. Remember, if you can hear thunder, you are close enough to
be struck by lightning.

.FLOOD IMPACT...
Storms today will produce torrential downpours when passing, with
a quick inch of rain possible. The greatest potential for heavier
amounts up to two to three inches of rain will be over the east
coast counties mid to late afternoon. The quick heavy rains may
lead to temporary flooding of urban and poorly drained low lying
areas, including streets, parking lots, culverts and water
retention ponds.

.MARINE THUNDERSTORM GUST IMPACT...
Wind gusts to around 35 knots will be possible over larger inland
lakes, as well as the Intracoastal and near Shore Atlantic waters.
Frequent cloud to water lightning, and locally higher waves will
also accompany storms today. Boaters should be alert for storms
moving quickly east at 15 to 20 knots today, and seek safe harbor
well in advance of any storms.


.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
Numerous showers and lightning storms are expected again on
Wednesday, with decreasing storm coverage from late week through
this weekend and into early next week as a drier air mass takes
hold across the region. The main thunderstorm hazards will
continue to be deadly cloud to ground lightning strikes, locally
heavy rainfall and gusty winds.



.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today and tonight.
However, spotters are requested to report any rainfall amounts of
2 inches or more to the National Weather Service in Melbourne.
