Coastal Flooding and Severe Weather Alerts for Northeast Florida

The National Weather Service (NWS) in Jacksonville has issued a Coastal Flood Warning for the St. Johns River Basin and coastal Northeast Florida, effective from 5 p.m. on October 3 until 5 a.m. on October 6, 2025. This warning is prompted by expected moderate flooding due to high tides and heavy rainfall, particularly affecting low-lying areas along the St. Johns River, the Intracoastal Waterway, and the coastline.

Residents in affected areas, including Coastal Duval, Flagler, and parts of St. Johns counties, should prepare for significant coastal flooding, with water levels anticipated to rise two to three feet above normal during high tides. The NWS has warned that numerous roads may be closed, and low-lying properties, including homes and businesses, could be inundated. Dangerous beach conditions are also expected, with high surf and strong rip currents posing risks to swimmers and surfers.

Heavy rainfall is forecasted throughout the weekend, with totals ranging from three to six inches along the coast and one to three inches inland. This precipitation is likely to exacerbate localized flooding, particularly in areas already prone to flooding. The NWS has advised residents to remain vigilant and heed local officials' updates.

While the NWS has issued these warnings, some residents express skepticism about the accuracy of such forecasts, citing past instances where predicted flooding did not materialize as expected. Local officials emphasize the importance of preparedness, urging residents to take the warnings seriously despite differing opinions on their severity.

Ben Nelson, a senior meteorologist at the NWS Jacksonville, stated, “Strong onshore winds will continue to create life-threatening rip currents, high surf, and moderate to major beach erosion around times of high tide.” He also noted that residents should maintain tropical readiness as the NWS monitors two tropical disturbances in the Atlantic, which could further impact local weather conditions.

There are discrepancies regarding the extent of flooding expected in various regions. While some forecasts predict moderate flooding, others suggest that impacts may be less severe. Additionally, the potential for tropical disturbances developing off the coast remains uncertain, with formation chances estimated at only 10% over the next week.
