Isolated to scattered storms will develop this afternoon over the interior and move toward the east, eventually colliding with the east coast sea breeze. The greatest coverage and intensity of storms will occur over east central Florida roughly between 4pm and 8 pm. These storms will be capable of strong, possibly damaging wind gusts of 40 to 60 mph and frequent lightning strikes. Seek shelter indoors when threatening weather approaches. Do not press your luck.

Peak heat indices will reach 102 to 107 this afternoon prior to onset of storms. If working or recreating outdoors, take frequent breaks out of the sun and drink plenty of water. .MARINE THUNDERSTORM GUST IMPACT... Scattered to numerous lightning storms will pose a hazard to boaters on inland lakes, the intracoastal and nearshore Atlantic waters. Wind gusts 35 to 45 knots will accompany the stronger storms with very heavy rain and frequent lightning strikes. Storm motion will be toward the east around 10 knots. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. Daily isolated to scattered afternoon lightning storms are expected through the week. Locally stronger storms will produce gusty winds and frequent lightning strikes. Heavy rainfall will lead to a daily threat for localized flooding this week. Afternoon peak heat indices expected to reach between 102 and 107 through the weekend. A Moderate risk of dangerous rip currents is expected at the beaches this weekend. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight.
