THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to numerous showers and thunderstorms will continue across
east central Florida through this afternoon and evening, with the
greatest coverage of storms along the coast. Storm motion will be
towards the northeast or east at 10 to 15 mph. The strongest
storms will produce dangerous cloud to ground lightning strikes,
gusty winds up to around 50 mph, and torrential downpours.

Remember that lightning can strike more than 10 miles away from a
storm, and just because you do not hear thunder, does not mean you
are safe from lightning. If you see lightning nearby, go into a
sturdy building and wait for the storms to pass before returning
outdoors.

.FLOOD IMPACT...
A localized flooding concern exists today, especially in Martin
County due to recent heavy rainfall. Storms will be capable of
producing 1 to 2 inches of rain in a short duration, and this
heavy rain could lead to minor flooding of streets, and low lying
and poor drainage areas.

.RIP CURRENT IMPACT...
There is a moderate risk of life threatening rip currents today at
all east central Florida beaches. While dangerous rip currents will
be present all day the risk will be greatest after 3 PM this
afternoon, due to tidal effects. Be sure to always swim at a life
guarded beach and never swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
Numerous showers and thunderstorms will move offshore this afternoon
and early evening, and some of the stronger storms could produce
wind gusts in excess of 34 knots.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Scattered to numerous showers and lightning storms will occur each
afternoon and early evening for the rest of this week and into
the weekend. Deadly cloud to ground lightning strikes, localized
flooding from heavy rainfall, and gusty winds are the main
threats.

The risk of rip currents will be remain moderate for the rest of
this week.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed this afternoon and tonight.
