Scattered to numerous showers and lightning storms will again develop into the afternoon and evening. Storms will move toward the east to northeast up to 10 to 15 mph and offshore, especially across northern portions of east central Florida, with slower storm motion farther south of the Orlando metro area. Main storm threats will be gusty winds up to 40 to 45 mph, occasional to frequent lightning strikes and torrential downpours. .EXCESSIVE RAINFALL IMPACT... Any slow moving or repeated rounds of heavier showers and storms will be capable of producing heavy rainfall of 2 to 4 inches, with localized totals of greater than 4 inches possible. These high rainfall amounts could lead to localized flooding of urban, low- lying, and poor drainage areas. Locations that have already received substantial rainfall the last few days will be more susceptible to flooding. .EXCESSIVE HEAT IMPACT... Heat and high humidity today will combine to produce peak afternoon heat index values of 103 to 107 degrees, leading to a Moderate to Major HeatRisk. .RIP CURRENT AND SURF IMPACT... A Moderate Risk for dangerous rip currents will exist at all central Florida Atlantic beaches. Always swim near a lifeguard, and never swim alone. .RIVER FLOOD IMPACT... The St Johns River Near Astor is forecast to remain in Minor Flood Stage through today due to light northerly winds and heavy rainfall that has occurred across the basin over the past few days. Should additional locally heavy rainfall develop over the basin through this weekend, additional rises will be possible. The river is forecast to gradually fall into Action Stage late in the weekend. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Scattered to numerous showers and lightning storms are forecast each afternoon and evening through this weekend into next week. Locally heavy to excessive rainfall leading to localized flooding, cloud-to-ground lightning strikes, and gusty winds will remain the primary threats. Heat and humidity will produce peak heat indices as high as 102 to 106 degrees on Sunday and Monday. At least a Moderate risk of dangerous rip currents is expected to continue at the beaches Sunday into early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. $$ Weitlich
