THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Isolated thunderstorms will move southwest at 10 to 15 mph across
east central Florida today. Main threats will be deadly lightning
strikes, wind gusts up to 35mph, and heavy downpours.

.FLOOD IMPACT...
With ample available moisture, storms today will be capable of
producing 1 to 2 inches of rainfall in a short period of time.
While storms are not expected to persist over an area for an
extended period of time, there will be a risk of ponding water or
poor drainage flooding, especially in areas that have received
rainfall over the last few days or where training storms set up.

.HIGH WIND IMPACT...
Areas along the Volusia Coast will see sustained wind speeds of 20
to 25 mph this afternoon, with higher gusts. These winds will
then spread southward through the overnight.

.COASTAL FLOOD IMPACT...
Minor beach erosion and coastal flooding will also be possible at
times of high tide into tonight. A Coastal Flood Watch will go
into effect for the Volusia and Brevard Coasts at 8pm this
evening.

.RIP CURRENT IMPACT...
There will be a high risk of life threatening rip currents at all
east central Florida beaches today. While the threat will be
present all day, it will be highest from 1PM to 7PM. Rip currents
are dangerous to all levels of swimmers. Entering the surf is not
advised.

.MARINE THUNDERSTORM GUST IMPACT...
Isolated thunderstorms will move toward the southwest at 10 to 15
mph today and be capable of producing occasional lightning
strikes and gusty winds up to 35 kts over the inland lakes and
Atlantic waters.

.WIND AND SEA IMPACT...
Hazardous to dangerous boating conditions expected to rapidly
develop today. Winds increasing to 20 to 25 knots this afternoon
north of Sebastian Inlet, before spreading further south to
Jupiter Inlet tonight. Seas building to up to 11 feet well
offshore by late this afternoon, then further increasing to up to
14 feet overnight. A Small Craft Advisory will go into effect at
2PM for areas north of Sebastian Inlet, with areas south of the
Inlet being added at 8PM.

.RIVER FLOOD IMPACT...
Local rainfall and tidal influences are forecast to keep river
levels of the Saint Johns at minor flood stage at Astor into
mid next week.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Scattered to numerous showers and a few lightning storms are
expected Sunday with locally heavy rain possible, mainly along
the east central Florida coast.

Very hazardous boating and beach conditions will further
deteriorate Sunday and continue into early next week, with windy
northeasterly winds increasing as large, long-period swells arrive
from distant Major Hurricane Teddy. Rough, pounding surf and a
high risk of numerous strong rip currents can be expected at area
beaches, along with the potential for moderate to significant
beach erosion during high tide cycles at least through Monday.
Conditions for coastal flooding are also expected to develop.
Coastal residents should be alert for later statements and take
necessary actions to protect flood-prone property.

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