Hazardous Weather Outlook...UPDATED National Weather Service Melbourne FL 920 AM EDT Fri Jul 27 2018 AMZ550-552-555-570-572-575-FLZ041-044>047-053-054-058-059-064-141- 144-147-280000- 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- 920 AM EDT Fri Jul 27 2018 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. .THUNDERSTORM IMPACT... Ample moisture and south to southwest flow will generate another round of scattered to numerous lightning storms today. Convection will develop by early afternoon along the east coast sea breeze near the Treasure coast before gradually transitioning inland into the late afternoon and early evening. Individual storms are expected to move toward the north to northeast at around 10 mph, though weak steering flow and numerous boundary interactions will lead to chaotic storm motion at times. The primary hazards will be torrential downpours, frequent lightning strikes, and gusty winds up to 45 mph in stronger storms. If outdoors and thunder is heard, seek shelter in an enclosed building or automobile. Picnic shelters, tents and golf carts offer no protection from lightning. Stay away from water as it is an excellent conductor of electricity. .FLOOD IMPACT... Slower moving showers and storms may produce rainfall amounts up to 2 to 3 inches in a short period of time. The heavy rain may produce temporary urban and poor drainage flooding. .RIP CURRENT IMPACT... A moderate risk of rip currents will exist at the beaches of east central Florida. Always swim within sight of a lifeguard. .MARINE THUNDERSTORM GUST IMPACT... Storms will develop over the mainland this afternoon and may affect the intracoastal and nearshore Atlantic waters as well as inland lakes. A few storms will be capable of producing frequent lightning strikes and wind gusts in excess of 30 knots. .RIVER FLOOD IMPACT... The Saint Johns River above Lake Harney near Geneva and at Astor remain in Minor Flood Stage, and River Flood Warnings are in effect for these areas. Sanford and Deland remain near or above Action Stage. The river is forecast to remain steady or slightly increase through the week. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY. Scattered to numerous afternoon and evening showers and thunderstorms are expected into early next week. The main storm threats will continue to be frequent lightning strikes, gusty winds and torrential downpours producing urban, river, and poor drainage flooding. A moderate risk of rip currents is expected through the weekend. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected today. Rainfall spotters are requested to report amounts greater than 3 inches to the Melbourne National Weather Service. Volkmer/Ulrich
