858pm EDT Sunday September 27 2020

Tonight...Deep moisture and instability that built up through the afternoon has fueled a large area of lightning storms and heavy rain. This cluster initially developed from Ocala to Palm Coast mid afternoon, then built south as the sea breezes collided. Storms have been moving slow, around 10-15 mph, due to weak steering flow. The main threats have been frequent to excessive lightning strikes and heavy rainfall.

Lightning detection systems indicate around 3000 cloud-to-ground lightning strikes have occurred since 6pm in central Florida. The large cluster of storms in Lake/western Orange Counties produced nearly 1700 cloud-to-ground lightning strikes in one hour. Rain amounts have also been quite high, with large parts of Lake, western Volusia, and now western Orange Counties seeing 2-4 inches and locally higher amounts.

Most of the heavy storms should remain and dissipate west of I-95, however expect some rain to eventually reach the coast from New Smyrna Beach south to Melbourne late this evening. Light to moderate rain is likely to linger across much of the I-4 Corridor and Brevard County well past midnight. The Treasure Coast should remain mostly dry tonight.

Temperatures settle into the mid to upper 70s overnight, with isolated showers possibly developing over the Atlantic waters late.

Marine
Tonight...Scattered showers and isolated lightning storms to slowly push offshore late this evening and overnight from Ormond Beach south to Melbourne. Heavy downpours and occasional lightning strikes will be the main threats. Otherwise, favorable conditions with light winds 10 knots or less and seas 1-3 feet.

Monday...Offshore moving afternoon and evening lightning storms are likely on Monday with the main hazards being frequent lightning strikes and gusty winds. Otherwise, expect seas 2-3 feet over most of the waters with 1-2 feet near the immediate coast in morning and into early afternoon.
