THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT.

.WIND AND SEA IMPACT...
A long period swell generated by Tropical Storm Jose will maintain 4
to 6 foot seas across the Gulf Stream waters with east to northeast
winds around 10 knots. Small craft operators should exercise caution
when venturing into the open Atlantic and around inlets during
the outgoing tide.

.RIVER FLOOD IMPACT...
Minor to moderate flooding along the Saint Johns River near Cocoa,
Geneva, Sanford, Deland and Astor are forecast to change little
through midweek. The Saint Johns River above Lake Harney near
Geneva is forecast to remain in major flood stage.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
Moderate swells generated by Jose will continue to diminish
through Thursday, but will produce marginal boating conditions
and a moderate to high rip current threat. Swells from Major
Hurricane Maria will increase by the upcoming weekend, leading to
very hazardous beach and boating conditions once again.

Elevated moisture levels are forecast into late week,
which will result in a low chance for lightning storms.

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