.NOW...

Scattered showers and storms will continue to develop across the
area through mid afternoon. Greatest coverage of this activity
through this timeframe is expected toward the east central Florida
coast with the inland moving east coast sea breeze and into areas
northwest of I-4 ahead of the west coast sea breeze. Storm motion
will generally be slow and erratic, but some gradual movement
toward the east to northeast is possible, potentially pushing just
offshore into the nearshore waters. Main storm threats will be
locally heavy rainfall of 2 to 4 inches, occasional to frequent
lightning strikes, and gusty winds up to 40 to 45 mph.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Numerous-to-widespread showers and lightning storms are forecast to
develop across east-central Florida once again this afternoon and
evening as the sea breeze boundaries develop and move inland. The
best chance for storms through the early afternoon is forecast near
the Treasure Coast as showers and storms develop along the east
coast sea breeze. The threat for storms will then shift farther
north and inland, especially along and near I-4, in addition to,
along and west of I-95 later this afternoon through this evening as
sea breeze and outflow boundary collisions increase. Storm motion
will be slow and erratic with a general movement toward the east to
southeast at 5 to 10 mph. Primary storm hazards will be flooding
from heavy rainfall, frequent cloud-to-ground lightning strikes, and
wind gusts up to 40 to 50 mph. Move indoors to safety at the first
sign of threatening skies or if you hear thunder.

.FLOOD IMPACT...
Slow moving storms will have the potential to produce torrential
rainfall totals of 2 to 4 inches with isolated higher amounts
possible in some locations. Locations that have received
persistent heavy rainfall over the last several days will have
an increased sensitivity to flooding today. Northern Lake,
western Volusia, Orange, Seminole, northern Brevard, Osceola, and
Okeechobee counties will be at most risk for flooding during
periods of heavy rainfall today. This will produce considerable
ponding of water on roadways and other poorly drained urban and
low-lying areas. Never drive through water of unknown depth, as
the water may be too deep to allow your vehicle to cross safely.

.RIP CURRENT IMPACT...
There will be a Moderate risk of dangerous rip currents at area
beaches today. While the threat for rip currents will be present all
day, it will be highest in the afternoon through early evening. Only
swim within sight of a lifeguard and never swim alone.

.MARINE THUNDERSTORM GUST IMPACT...
A few stronger storms may be capable of wind gusts near 35 knots
over inland lakes and the Intracoastal and near shore Atlantic
waters. Mariners should watch for storms mainly approaching from
the west-southwest today. However, storm motion will mostly be
slow and erratic.

.WATERSPOUT IMPACT...
The combination of very moist air and light winds may lead to a
brief isolated waterspout over the Atlantic waters, in addition
to, along and near the Intracoastal Waterway, and larger inland
lakes. If you see a funnel cloud or waterspout start to develop,
give it a wide berth, and, if possible contact the National
Weather Service in Melbourne.

.RIVER FLOOD IMPACT...
Repeated rounds of heavy diurnal rainfall over the past week has
caused water levels along the Saint Johns River to rise, especially
at Astor and near Geneva. The river at Astor is forecast to hover
around flood stage through Thursday and reach Action Stage near
Geneva today, cresting by the weekend.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Lightning storm coverage will remain scattered through Saturday and
then isolated into early next week. Flooding, torrential downpours,
cloud-to-ground lightning strikes, and gusty winds will be the main
storm threats.

The risk of dangerous rip currents is expected to be moderate
through late week.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed this afternoon and tonight,
however, spotters are encouraged to report any rainfall amounts
greater than three inches and any observed flooding issues from
heavy rainfall.
