Hazardous Weather Outlook...UPDATED National Weather Service Melbourne FL 1032 AM EDT Mon Jun 26 2017 AMZ550-552-555-570-572-575-FLZ041-044>047-053-054-058-059-064-141- 144-147-270245- Flagler Beach to Volusia-Brevard County Line 0-20 nm-Volusia- Brevard County Line to Sebastian Inlet 0-20 nm- Sebastian Inlet to Jupiter Inlet 0-20 nm-Flagler Beach to Volusia- Brevard County Line 20-60 nm-Volusia- Brevard County Line to Sebastian Inlet 20-60 nm- Sebastian Inlet to Jupiter Inlet 20-60 nm-Inland Volusia County- Northern Lake County-Orange-Seminole-Southern Brevard County- Osceola-Indian River-Okeechobee-St. Lucie-Martin- Coastal Volusia County-Southern Lake County- Northern Brevard County- 1032 AM EDT Mon Jun 26 2017 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. .THUNDERSTORM IMPACT... An approaching frontal boundary and increased moisture in the atmosphere will produce a higher coverage of afternoon showers and thunderstorms. Initial development of isolated lightning storms is expected along the east coast sea breeze as it pushes inland from the coast early this afternoon. Coverage and intensity of thunderstorms will increase late this afternoon and early evening over the interior, especially along the Interstate 4 corridor and Osceola county. Some of the storms will push back toward the Volusia and Brevard County coasts. The primary hazards will be cloud to ground lightning, gusty downburst winds, and heavy rainfall. Storm motion will be generally toward the northeast around 10 mph but thunderstorms that form as a result of boundary collisions will exhibit slow and erratic movement. .FLOOD IMPACT... Slow moving lightning storms will be capable of producing locally heavy rainfall late this afternoon and this evening across parts of Lake, Volusia, Seminole, Orange, Osceola, and Brevard counties. Rainfall amounts of 2 to 4 inches 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 will be capable of producing dangerous lightning strikes and gusty downburst winds late this afternoon and this evening. Most of the storms will stay over land and affect inland lakes but there is chance for a few storms or their outflows to push back to the Volusia and Brevard coasts. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. Scattered lightning storms are expected each afternoon this week, with the highest storm coverage forecast through Tuesday as a weak frontal boundary pushes into the area and stalls. The primary threats will be dangerous lightning strikes, gusty winds and locally heavy rain. .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. 15
