Coastal Flood Advisory: Minor Tidal Flooding Expected Tonight in New Castle County

Sunday, February 22, 2026 at 6:46 PM

A Coastal Flood Advisory is in effect for New Castle County from midnight to 4 AM Monday, with up to six inches of tidal flooding expected in low-lying coastal areas.

Residents in New Castle County, Delaware and Salem County, New Jersey should prepare for minor tidal flooding tonight as the National Weather Service has issued a Coastal Flood Advisory effective from midnight until 4:00 AM Monday morning. Up to six inches of water above ground level is expected in low-lying areas near shorelines and tidal waterways. The flooding will primarily affect the most vulnerable roadways along tidal areas, with some partial or full road closures possible. Officials warn that additional tidal flooding may occur through Monday night’s high tide cycle, so residents should remain vigilant beyond the initial advisory period. For your safety, do not attempt to drive through flooded roadways – the water may be deeper than it appears and can cause serious vehicle damage or put you in danger. Avoid parking in areas prone to tidal flooding. While this is considered minor flooding, it’s important to take precautions and avoid affected areas when possible. The advisory expires at 4:00 AM Monday, but conditions should be monitored throughout the day.
