The east and west coast sea breezes are expected to form by early afternoon and push slowly inland. Scattered showers and lightning storms will form along the breeze boundaries, moving south around 10 mph. Shower and storm coverage will increase during the mid to late afternoon over the interior counties, with the best chance for storms expected along and west of the Florida Turnpike The strongest storms will be capable of producing frequent cloud to ground lightning strikes, brief wind gusts to around 35 to 45 mph, and rainfall rates up to two inches per hour. Cease outdoor activities and move indoors if thunder is hear or at the first sign of threatening skies. .EXCESSIVE HEAT IMPACT... Afternoon temperatures in the middle to upper 90s will combine with light winds and high humidity to generate peak heat indices around 105 degrees across east central Florida, and high as 110 in some locations. If you will be outside engaged in any work or recreational activity today, be sure to stay hydrated and take frequent rest breaks indoors. .RIP CURRENT IMPACT... A small but persistent long period swell coupled with a high astronomical tide will generate a MODERATE rip currents threat along the beaches of east central Florida. The threat will be highest between Noon and 6:30 PM due to tidal effects. To reduce your chance of being caught in the seaward pull of a rip current, always swim within sight of a lifeguard and never swim alone. .MARINE THUNDERSTORM GUST IMPACT... Lightning storms will be capable of producing wind gusts to around 35 knots over larger inland lakes, mainly over the interior counties following the late day collision of the sea breezes. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. Storms will increase this weekend into early next week as moisture increases across Florida. The main storm threats will continue to be deadly cloud to ground lightning strikes, gusty winds and local heavy rainfall. Low daytime cloud cover and rain chances will result in abnormally hot temperatures through the late week. Afternoon heat indices of around 105 degrees or so are forecast. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated. MB/JP
