This Hazardous Weather Outlook is for Northeast Florida,
Southeast Georgia and the Adjacent Coastal Waters.

.DAY ONE...Tonight...

Scattered to storms across inland southeast Georgia are
expected to dissipate by after midnight. Isolated storms
will continue towards the gulf coast with activity possibily
increasing in coverage east of the I-75 corrridor late
tonight. The stronger storms will produce frequent lightning
and locally heavy rain.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

Tropical Depression Eight will pass several hundred miles east of
Jacksonville early this week but may produce longer period swells
at the coast which would enhance the risk of rip currents.

Scattered to numerous storms are expected through the period
mainly during the afternoon and evening hours. The main threats
will continue to be locally heavy rainfall but strong storms with
gusty winds and excessive lightning will be possible as well.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated at this time.
