THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Moisture will increase across east central Florida today as
tropical wave moves toward south Florida. Scattered showers and
thunderstorms will initially develop over the Treasure Coast and
Lake Okeechobee region through early afternoon, becoming numerous
in the mid to late afternoon. Slightly drier air along and north
of the I 4 Corridor will keep thunderstorm activity scattered
across Lake and Volusia counties. Stronger storms will be capable
of producing wind gusts over 40 mph, dangerous lightning, and
locally heavy rain. Cease outdoor activity and move indoors at
the first sign of threatening weather, especially if thunder is
heard.

.FLOOD IMPACT...
Deep tropical moisture and the approach of a tropical easterly
wave will increase the risk for locally heavy rainfall across
Okeechobee county and the Treasure coast through tonight. Heavy
rainfall amounts up to two to three inches are possible in
localized areas that see repeated showers and storms. The heavy
rain may cause minor flooding of roadways, and also poor drainage
and low-lying areas.

.MARINE THUNDERSTORM GUST IMPACT...
Thunderstorms will be capable of producing wind gusts above 35
knots across the Atlantic waters of east central Florida, as well
as the Intracoastal Waterway and the interior lakes this
afternoon and evening. Storm motion today will be west around 10
knots.

.RIVER FLOOD IMPACT...
The Saint Johns River near Geneva remains in action stage with a
slow rise in the river level expected. When action stage is
reached, no wake zones go into effect and county parks are closed
for areas east of Lake Monroe to Lake Harney.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
Shower and thunderstorm activity will increase into the weekend
as the tropical wave moves into the eastern Gulf of Mexico.
Scattered to numerous showers and thunderstorms are expected.
Inland locations will be favored for higher storm coverage this
weekend. As this wave approaches Florida, winds over the Atlantic
waters will increase, which may generate hazardous boating conditions
this weekend.

River levels along the Saint Johns River near Geneva will continue
to slowly rise and remain above action stage into early next week.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed through tonight. Rainfall
spotters should report rainfall amounts over two inches or observed
flooding to the National Weather Service in Melbourne.

...Brief Heavy Rain in Passing Showers and Storms...

An area of low pressure located in vicinity of the lower Southeast
Florida Coast and Upper Keys was helping to develop scattered
showers and thunderstorms over East Central Florida and the adjacent
coastal waters. They were moving steadily onshore from Daytona
Beach, to Cape Canaveral, to Stuart. They will continue to move well
inland reaching near Sanford, Orlando, Leesburg, Lakeland, and Lake
Okeechobee. Many will continue onward toward the Gulf Coast.
Movement will be west southwest at 15 mph.

Rainfall will be brief but heavy with each passing shower or storm
this afternoon. A steady supply of new showers and storms will be
scattered across the marine area and then move onshore.

BE ADVISED: There is the potential for excessive rainfall through
tonight for interests along the Treasure and Space Coasts and also
in vicinity of Lake Okeechobee. One to three inches of rain, and
up to four to five inches in spots, could occur over the next day
or two. This includes the threat of heavy rain during the
