Coastal Flood Warning Issued for Coastal Duval County

October 10, 2026 · wweather1 editorial · 2 min read

The National Weather Service in Jacksonville, Florida, has issued a Coastal Flood Warning for Coastal Duval County, effective until Sunday, October 11, at 6:00 AM EDT.

The National Weather Service has issued multiple alerts for the region, including a Coastal Flood Warning indicating significant coastal flooding, a Coastal Flood Advisory for expected minor coastal flooding from 6 AM to 5 PM EDT Sunday, and a High Rip Current Risk highlighting dangerous rip currents through late tonight.

Impacts from the severe weather include the potential for numerous road closures and the inundation of low-lying property, which encompasses homes, businesses, and critical infrastructure. Additionally, some shoreline erosion is expected to occur during the warning period.

The high rip current risk poses a severe hazard, as rip currents are capable of sweeping even the best swimmers away from the shore and into deeper water.

Why it is dangerous and what to do

⚠️ Safety
• Take necessary actions to protect flood-prone property.
• Do not drive around barricades or through water of unknown depth if travel is required.
• Swim near a lifeguard and remain aware of dangerous rip currents.
• If caught in a rip current, relax, float, and swim parallel to the shoreline rather than against the current.
