A moist and unstable air mass remains in place over central Florida, with numerous showers already having formed over western Florida late this morning. As this activity along and ahead of the west coast sea breeze moves northeast at around 10 MPH into the central and eastern peninsula, it will further increase in coverage as well as intensity becoming widespread as it interacts with showers and storms that are expected to form along local sea and lake breezes. The main storm hazards will be cloud to ground lightning strikes and torrential rainfall, especially within stronger storms. A few wind gusts to 30 or 40 MPH will also be possible. .FLOOD IMPACT... Some of today's storms will be able to produce torrential downpours of 2 to 3 inches in a 60 to 90 minute period. This will result in considerable water ponding on roadways and other poorly drained and low lying areas. .MARINE THUNDERSTORM GUST IMPACT... Numerous showers and thunderstorms will occur over land this afternoon, with the activity pushing northeast at 10 knots into the nearshore Atlantic waters. In addition to hazardous lightning strikes, there is a chance for wind gusts to around 35 knots. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY. Moist conditions will remain in place into the middle of next week. Little, if any, interruption to the pattern of numerous afternoon showers and thunderstorms is expected. The highest coverage will shift to the western half of the peninsula early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation is not anticipated. Rainfall observers are requested to report measured rain amounts of three inches or greater to the National Weather Service in Melbourne. Bragaw/Cristaldi
