442 AM EDT Thu Aug 17 2017 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. .THUNDERSTORM IMPACT... Scattered to numerous afternoon and early evening showers and lightning storms are expected once again across east central Florida, mainly between about 2 PM and sunset. Storms will initially form out ahead of the local east and west coast sea breezes into early to mid afternoon, with additional boundary collisions creating greater coverage from late afternoon into early evening. Movement will be slow and erratic. Greatest coverage from late afternoon into early evening is forecast from Lake George southward through Osceola County and along the Kissimmee River into Okeechobee County. The main storm threats will be cloud to ground lightning strikes, wind gusts of 35 to 45 mph, and locally heavy rainfall amounts up to around 2 to 3 inches in a 60 to 90 minute period. Move indoors to safety if skies look threatening, or you hear thunder. .EXCESSIVE HEAT IMPACT... The combination of hot temperatures and high humidity may create a dangerous situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Highest heat index values will soar to between 100 and 106 from late this morning into early evening across much of east central Florida. .RIP CURRENT IMPACT... Ocean conditions will lead to a moderate threat for dangerous rip currents in the surf zone at east central Florida beaches. The threat will be highest from this morning into early afternoon and again around mid evening due to tidal effects. Check with your local beach patrol for additional information about ocean hazards. Swim only within sight of a lifeguard, and never swim alone. .MARINE THUNDERSTORM GUST IMPACT... A few stronger storms could produce wind gusts up to 35 knots over some of the larger inland lakes, as well as the Intracoastal and near shore Atlantic Waters, especially north of Cape Canaveral. .WATERSPOUT IMPACT... Marine interests should be alert for the potential of waterspouts. Showers and lightning storms can produce short-lived waterspouts with little or no advance warning. Boaters should seek safe harbor if a waterspout is spotted. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. Afternoon lightning storms will remain in the forecast through the weekend and into early next week. The main thunderstorm hazards will be frequent cloud to ground lightning, gusty winds, and locally heavy rainfall. The Rip Current threat is also expected to remain greater than normal for the next couple days due to a small lingering swell from distant Hurricane Gert. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated today; however, spotters are encouraged to report any rain amounts of 3 inches or greater. $$ Sedlock
