As Tropical Storm Debby increases the wind energy over the Florida Peninsula, there is a Marginal to Slight Risk of a few strong to severe storms today across East Central Florida. Wind gusts to tropical storm force will be the primary threat. One or two tornadoes also cannot be ruled out. Additionally, a Tornado Watch has been issued for Lake, Seminole, Orange, Osceola, Okeechobee, and Volusia counties through 8 PM. Ensure you have multiple ways of receiving weather alerts. .EXCESSIVE RAINFALL IMPACT... There is a Slight Risk of excessive rainfall today near and north of Interstate 4 and a Marginal Risk elsewhere. Repeated rain bands from Tropical Storm Debby could result in localized flooding, especially in urban and poorly-drained areas. .RIP CURRENT AND SURF IMPACT... A High risk of dangerous, life-threatening rip currents exists today at all central Florida Atlantic Beaches. This will be accompanied by a longshore northward-flowing current and breakers increasing to 4-5 feet in the surf zone. Entering the surf is strongly discouraged! Localized minor beach erosion or scouring may occur at times of high tide. .WIND AND SEA IMPACT... A Small Craft Advisory continues for the local Atlantic waters. Southeast winds around 25 knots with gusts up to 35 knots and seas of 4-7 feet are forecast. Boating conditions will remain hazardous through the period. Additionally, a Tornado Watch is now in effect through 8 PM across the nearshore Volusia waters. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY. Tropical Storm Debby is forecast to make landfall somewhere near the Florida Big Bend on Monday, then continue slowly moving northeastward. On Monday, numerous showers and storms are forecast. The primary hazards from storms will be gusty winds of 40 to 50 mph and occasional lightning. There is also a low chance for a tornado or two, especially near and north of Interstate 4. Windy conditions are also expected outside of showers and storms. Daily chances of mainly afternoon and evening showers and storms will continue through the rest of the week. Boating conditions will remain hazardous through early this week as winds remain elevated. Additionally, there will be at least a moderate risk of dangerous rip currents at area beaches. Finally, hot temperatures will make a return. Heat indices up to 107 are forecast through Wednesday before potentially increasing toward 105 to 110 degrees later this work week. .SPOTTER INFORMATION STATEMENT...
