THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Another day of numerous showers and lightning storms can be
anticipated across east central Florida. Strong to isolated
severe storms are most likely to occur in the afternoon and early
evening hours. The strongest storms will produce frequent cloud-
to-ground lightning, gusty winds from 40 to 60 miles per hour, and
hail to quarter size. Remember to seek shelter indoors when you
hear thunder.

.FLOOD IMPACT...
Where repeated rounds of thunderstorms occur, localized rain
amounts up to 4 inches in a short time are possible. This could
lead to flooding of low-lying areas, especially where heavy
rainfall has already fallen the last few days. If you encounter
flooding, turn around, don't drown.

.RIP CURRENT IMPACT...
A Moderate risk of life-threatening rip currents continues at all
east central Florida Atlantic coast beaches. Check with your
local beach patrol for additional information about ocean hazards.
Remember to swim only within sight of a lifeguard, and never
enter the ocean alone.

.MARINE THUNDERSTORM GUST IMPACT...
Wind gusts over 30 knots from the strongest storms will affect
inland lakes and waterways today. Near and offshore waters could
also experience this activity this evening as storms drift back
toward the coast.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
Unsettled weather is expected to continue for much of the work
week. Low pressure is forecast to form near or east of Florida by
Wednesday or Thursday. Abundant moisture will remain in place,
leading to more opportunities for heavy showers and lightning
storms. A few of the strongest storms will be capable of producing
frequent cloud-to-ground lightning strikes, gusty winds from 40
to 50 mph, and hail to quarter-size.

There will be a continued chance for localized flooding where
repeated rounds of heavy rainfall occurs through the work week.

A Moderate risk of dangerous rip currents is expected to continue at
all east central Florida Atlantic beaches this week.

.SPOTTER INFORMATION STATEMENT...
Spotters should monitor the weather and self activate if needed.
