Jacksonville, Fla. – Thunderstorms and dangerous heat will grip northeast Florida through the weekend, bringing the potential for flooding downpours and hazardous beach conditions. A High Surf Advisory and rip current threat remain in effect along the Jacksonville coast until Thursday evening, as waves and strong currents make swimming dangerous.
According to the National Weather Service, showers and thunderstorms will become widespread Thursday afternoon, with heat index values climbing to near 105 degrees before storms move in. New rainfall amounts could trigger localized street flooding, especially in Duval and St. Johns counties.
Storms will continue each afternoon and evening through Sunday, with the heaviest activity expected Friday and Saturday. Winds up to 15 mph and frequent lightning may disrupt outdoor plans across Jacksonville, Orange Park, and Fernandina Beach. Motorists should be alert for ponding on roads during the evening commute, particularly on I-95 and I-10.
Residents are urged to limit outdoor activity during peak heat hours, stay hydrated, and avoid the ocean while surf advisories remain active. Power outages are possible if severe storms strengthen along the coast.
Thunderstorm chances remain elevated into early next week, with daily rain chances holding at 40 percent or higher.
