This Hazardous Weather Outlook is for east central Florida.

.DAY ONE...Today and tonight.

.THUNDERSTORM IMPACT...
Scattered to numerous showers and scattered lightning storms are
expected this afternoon with storm motion generally to the east
at 5 to 10 mph. Primary storm threats remain gusty winds up to 30
to 45 mph, occasional to frequent lightning strikes, and locally
heavy rainfall.

.EXCESSIVE RAINFALL IMPACT...
Rainfall amounts of 1 to 3 inches (locally up to 4 inches) over
already saturated ground will have the potential to produce minor
flooding of urban, low-lying, and poor drainage areas.

.EXCESSIVE HEAT IMPACT...
Very warm temperatures and high humidity will combine to produce
peak afternoon heat index values of 102 to 107 degrees with up to
110 degrees across portions of Okeechobee, Saint Lucie and Martin
counties. A Heat Advisory is in effect this afternoon for the
aforementioned three counties. A Moderate to High Heat Risk
exists across all of east central Florida today. This level of
heat can affect anyone without adequate precautions. It is
recommended to take frequent breaks from the heat and stay
hydrated, especially if spending extended periods of time outdoors
during the afternoon.

.RIP CURRENT AND SURF IMPACT...
A Moderate risk of life-threatening rip currents exists at all
central Florida Atlantic beaches. Remember to always swim near a
lifeguard and never enter the water alone.

.RIVER FLOOD IMPACT...
The Saint Johns River at Astor is forecast to remain in Moderate
Flood stage. The potential for small additional rises exists if
locally heavy rainfall develops over the river basin. Please
refer to the associated Flood Warning for the Saint Johns River at
Astor for more information.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
Scattered showers and lightning storms are forecast on Sunday into
next week. The main hazards will be locally heavy rainfall,
lightning strikes, and gusty winds.

Warm temperatures and high humidity will produce peak heat index
values up to 100 to 107 degrees through early next week. Slightly
lower humidity mid week next week will allow heat index values to
fall into the low 100s.

A Moderate to High risk of dangerous rip currents is expected at
the beaches through the extended.

High astronomical tides will produce above normal water levels
around the times of high tide from Sunday evening through much of
next week. This may cause minor inundation of low lying
properties near inlets, nearby areas along the Intracoastal
Waterway, and adjacent canals. Some docks may briefly get
overtopped by water.

Increasing long period swells will build seas Sunday through
Tuesday with poor to hazardous boating conditions forecast over
the local Atlantic.

Flooding along the Saint Johns River (particularly at Astor) will
continue Sunday through the middle of next week.

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