Flash Flood Warning Issued for Clay and Duval Counties

October 10, 2026 · wweather1 editorial · 2 min read

The National Weather Service in Jacksonville has issued a Flash Flood Warning for north central Clay County and southwestern Duval County in northeastern Florida, effective until 12:15 AM EDT on October 10.

At 10:10 PM EDT on October 9, Doppler radar indicated thunderstorms producing heavy rainfall across the warned area. Radar reports show that between 1 and 3 inches of rain have already fallen, with additional amounts of 1 to 3 inches possible. Flash flooding is ongoing or anticipated to start shortly.

The severe weather is expected to cause flash flooding in small creeks and streams, urban neighborhoods, highways, streets, underpasses, and other poor drainage or low-lying areas. Mccoy Creek and Hogan's Creek are specifically expected to be impacted by rising water levels.

Locations listed by the weather service that will experience flash flooding include Jacksonville, Orange Park, Middleburg, Bellair-Meadowbrook Terrace, Normandy, Cecil Field, Ortega, Oakleaf Plantation, Lakeside, and Doctors Inlet. Affected roadways near waterways include the intersection of Mccoy Creek Blvd and King Street, alongside N Market, N Newmans, Hubbard, and Orange Streets near Confederate Park.

Why it is dangerous and what to do

• Turn around, don't drown when encountering flooded roads, as most flood deaths occur in vehicles.
