THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...

interior into early to mid afternoon and then move toward the
coastal areas of east central Florida into the late afternoon
hours. Storms will move east-northeast at 20 mph with some storms
expected to become strong as they interact with the east coast

knots. Boaters should be prepared to seek safe harbor as storms
approach the intracoastal and near shore Atlantic waters.

.RIP CURRENT IMPACT...

to a Moderate risk of life-threatening rip currents at east central
Florida beaches. Remember to swim within sight of a lifeguard.

closures that might be in effect for your county or community.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
