THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Higher moisture will spread back into the area today from the
southeast. This will bring a chance for afternoon storms, with the
highest coverage expected to be south of Orlando and Cape
Canaveral. The main storm threats will be occasional lightning
strikes and gusty winds to around 40 mph.

.RIP CURRENT IMPACT...
Onshore winds will cause more wave action in the surf zone today,
which will lead to a moderate rip current risk. Only swim near a
lifeguard.

.MARINE THUNDERSTORM GUST IMPACT...
A southeast wind flow will increase slightly today and raise
moisture levels. Expect onshore moving showers and storms to
become scattered by this afternoon. Storm motion will be to the
northwest around 10 knots and gusty winds 30 to 35 knots are
possible.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
After diminished rain chances on Monday, another inverted trough
will move in from the Atlantic Tuesday into Wednesday and bring
increased chances for showers and storms. Higher moisture will
linger into the upcoming weekend and bring a greater than normal
chance for showers and storms.

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