THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
A very moist air mass will lead to scattered thunderstorms this
afternoon and evening. The highest coverage is expected to occur
from Lake and interior Volusia counties, across metro Orlando into
Osceola county. A few strong storms will produce frequent
lightning strikes and gusty winds 40 to 50 mph. Storm motion will
be slow and erratic, but generally building southward through the
afternoon.

.FLOOD IMPACT...
A few slow moving and strong thunderstorms will be capable of
producing quick 2 to 3 inch downpours. Considerable water ponding
on roadways and other poorly drained areas will occur.

.EXCESSIVE HEAT IMPACT...
The combination of hot temperatures and high humidity will produce
heat indices between 100 and 105 from late this morning into
afternoon. If engaging in outdoor activities, consume sports
drinks and plenty of water. Also take breaks in the shade or air
conditioning.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered afternoon storms over land will be capable of producing
wind gusts over 40 mph, mainly across interior counties.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
The greatest chance for strong afternoon storms is expected to
shift to interior sections over the weekend and through early next
week as an onshore wind flow develops and gradually freshens.
These onshore winds will also start to make the surf zone more
hazardous, especially due to rip currents.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated today, however spotters are
encouraged to report any rain amounts of 3 inches or greater.
