Delaware – Water is expected to push onto low-lying roads near the Delaware River before sunrise Sunday, creating hazardous travel conditions as coastal flooding and rain arrive together.
According to the National Weather Service in Mount Holly, a Coastal Flood Advisory remains in effect from 11 p.m. this evening until 3 a.m. Sunday, with up to one foot of inundation possible in vulnerable shoreline areas. Flooding will begin on the most flood-prone roads, especially near tidal waterways in New Castle County and nearby parts of Salem County, New Jersey.
In the Wilmington area, roads closest to the river, including stretches near Route 9, I-495, and low-lying access points, may see water coverage during high tide. Some closures are possible if water levels rise quickly. Drivers should avoid flooded roadways and plan alternate routes.
Rain develops into Sunday, with showers becoming more widespread by morning. While rainfall totals remain light, wet pavement and reduced visibility could slow travel across I-95 and surrounding city streets. Use headlights and allow extra stopping distance.
Conditions improve later Sunday as the system moves offshore, but cooler air follows. Monday brings drier weather with highs in the mid-50s, while early morning temperatures dip into the mid-30s. Any leftover moisture could create isolated slick spots on bridges.
A gradual warm-up returns by midweek, with highs climbing into the 70s by Wednesday.
