Coastal Flood Advisory Issued for Delaware Areas
US · Published Sep 22, 2026
A Coastal Flood Advisory is in effect for Kent and Inland Sussex counties in Delaware from 4 PM to 10 PM EDT on Tuesday, September 22,
Additionally, a Coastal Flood Watch has been issued for the same areas, effective from Wednesday afternoon through late Thursday night. The advisory warns of up to one foot of inundation above ground level in low-lying areas near shorelines and tidal waterways. The watch anticipates one to two feet of inundation, with moderate tidal flooding potentially continuing through Friday evening's high tide. These conditions are attributed to a cold front that has brought cooler, damp weather to the region.

Impact & Risks

The flooding could lead to widespread roadway inundation in coastal and bayside communities, making many roads impassable. Vulnerable structures in low-lying areas may experience some damage. Residents in affected areas should prepare for potential disruptions and take precautions to protect life and property. Moderate tidal flooding is expected to persist, particularly during high tide periods, increasing the risk of localized damage and travel hazards.
