Local winds near the surface will assume more of an onshore component today. As a result, coverage of showers and thunderstorms will favor inland locations during the afternoon. Plenty of moisture from an old frontal trough, as well as from recent generous rains, will ensure that coastal locations will not be left out having an early start along the sea breeze. Primary hazards will be cloud-to-ground lightning and locally heavy rain today. However, wind gusts to 45 mph are cannot be ruled out. Storm motion will be toward the inland direction around 10 mph. .FLOOD IMPACT... Slow moving lightning storms will be capable of producing locally heavy rainfall this afternoon. Rainfall amounts of 2 to 4 inches in a 60 to 90 minute period will be possible in a few spots which will cause temporary flooding of roadways and low lying areas. .RIP CURRENT IMPACT... An east swell will produce a moderate risk of rip currents at the beaches of east central Florida. Always swim within sight of a lifeguard. .MARINE THUNDERSTORM GUST IMPACT... Scattered lightning storms are expected to develop near the coast along the sea breeze and push farther inland while becoming more numerous. Marine impacts to the intracoastal waterways will be more prevalent from the Cape south along the Treasure Coast. However, inland lakes will actually be more at risk to strong thunderstorm gusts during the mid to late afternoon. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. Scattered lightning storms are forecast to continue into the Fourth of July weekend. The primary threats will be dangerous lightning strikes, gusty winds, and locally heavy rain. While the highest chances for afternoon thunderstorms is expected across inland areas, coastal locations will also see a threat of lightning activity each day. A moderate risk of rip currents will continue. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today, however spotters are asked to report rainfall amounts of greater than 3 inches or observed flooding. DWS/SK
