THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
A cool front will be passing south through the forecast area
today and become nearly stationary by tonight. Scattered to
numerous showers will occur along and ahead of the front, with
additional activity expected for Volusia and northern Brevard
Counties due to a maritime wind surge approaching from the
northeast behind the front. Thunderstorms will be isolated with
occasional wind gusts to about 35 mph. Severe storms are not
expected, although locally heavy rain will be a primary concern.

.FLOOD IMPACT...
Scattered to numerous showers and isolated thunderstorms today in
vicinity of a cool front passing south through East Central
Florida today bringing periods of heavy rain. The front will
stall near South Florida by tonight. Behind the front, a surge of
maritime winds from the northeast will offer increased rain
opportunity through the day into tonight, especially along the
coast, and particularly for Volusia County and north Brevard
County where a Flood Watch is in effect. Recurring heavy rain may
produce 1 to 3 inches across the area, with local 3 to 5 inches
possible. The ground in many places is already saturated so
rainfall could turn to runoff quickly. Additional rain could also
further aggravate flooding along the Saint Johns River if any
prolonged heavy rain works its way inland. Listen for flood
warnings and be ready to act. Rapid ponding of water may also
cause significant driving hazards in the aforementioned areas.
Never drive through places where water of unknown depth covers
the road.

.RIP CURRENT IMPACT...
A northeast wind surge behind a passing cool front will offer
adverse beach conditions today, especially for Volusia and Brevard
County Beaches. The surf will become progressively rough and the
risk for rip currents will become high for Cocoa Beach north
through Daytona Beach, and moderate elsewhere southward though
the remainder of the Space and Treasure Coasts. Beach-goers are
urged to stay out of the surf today.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered to numerous showers with isolated thunderstorms may
produce local convective wind gusts to 30 knots, especially in
vicinity of a passing cool front, as well as along the Volusia
and Brevard County coasts as today and tonight unfolds.

.WIND AND SEA IMPACT...
Hazardous boating conditions north of Sebastian Inlet from the
coast out to 60 nautical miles due to a passing cool front and
associated wind surge behind it. Winds will become northeast to 20
to 25 knots and build seas up to 6 to 8 feet nearshore and 8 to 10
feet offshore by tonight. South of Sebastian Inlet, seas will
build to 5 to 7 feet by tonight due to northeast wind of 15 to 20
knots.

.RIVER FLOOD IMPACT...
The middle and upper Saint Johns River basin remains in flood with
only a slight decrease in river levels forecast over the next
several days.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
Scattered to numerous showers with isolated lightning storms are
forecast across East Central Florida for Wednesday. Locally heavy
rain may occur at times, especially along the coast. Improving
conditions are then forecast for later in the week.

Boating conditions will be poor to hazardous much of the remainder
of this week due to increased winds and seas. Also, at the beaches
the surf may become rough at times. A moderate risk of rip
currents will be recurring.

.SPOTTER INFORMATION STATEMENT...
Rainfall Spotters may be needed to self activate today, especially
in Volusia and Brevard Counties.
