THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Sufficient daytime heating combined with deep tropical moisture
and local sea/lake breeze effects will produce numerous to
widespread showers and scattered lightning storms across east
central Florida today. Activity will be limited to light showers
prior to noon this morning, but increase throughout the afternoon
and continue through early evening. The highest coverage of
precipitation today is expected between 2 and 8 PM, as storms move
fairly quickly toward the northeast at around 25 to 30 MPH in
southwest steering flow.

Torrential rain, brief gusty winds of 40 to 50 MPH, and frequent
cloud to ground lightning strikes are possible with the strongest
storms today. Move indoors to safety if you hear thunder or if
skies look threatening.

.FLOOD IMPACT...
Between 1 and 3 inches of rainfall in a one to two hour period is
expected with the most intense storms this afternoon, especially
over the east coast counties. This may cause temporary inundation
of roads and other poor drainage areas, especially in locations
which received heavy rainfall over the past few days. Motorists
should reduce their speed when encountering heavy rain, and never
drive into areas where water covers the roadway.

.RIP CURRENT IMPACT...
A longshore current running form south to north is expected in
the surf zone at the central Florida Atlantic beaches again today
due to a persistent moderate southeast breeze. To avoid the
northward pull of a longshore current today, swim toward shore,
but remember to avoid any rip currents that you might encounter.
Never try and swim directly against any current, whether it is a
rip current or a longshore current, and always swim in sight of a
lifeguard.

.MARINE THUNDERSTORM GUST IMPACT...
Wind gusts of at least 35 knots will be possible over the near
shore Atlantic, Intracoastal Waterway, and on inland lakes.
Boaters should be on the lookout for storms approaching quickly
from the southwest, and move to safe harbor if storms threaten.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
The low pressure system over the northeast Gulf will move inland
over the Gulf Coast states and weaken by late today, however,
deep tropical moisture will remain in place through this weekend.
Numerous showers and a few storms are expected each day, mainly
during the afternoon and early evening. Locally heavy rain is
expected, with accumulations of 1 to 3 inches in the most intense
storms, along with deadly cloud to ground lightning and brief
gusty winds.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today.
