Delaware residents face a mix of hazards and hope this week. A coastal flood advisory takes effect today, Wednesday, October 1, from 5 p.m. to 9 p.m. The warning covers low-lying areas near the Delaware River and tidal waterways, especially in New Castle County, DE, and Salem County, NJ.
According to the National Weather Service, up to one foot of flooding is possible in vulnerable areas. Drivers are urged not to attempt travel on flooded roads, including sections near Route 9 and riverfront neighborhoods. Even shallow water can damage vehicles and create dangerous conditions.
After today’s risks, skies clear and fall sunshine dominates the weekend. Thursday brings a high near 69 degrees with calm winds. By Friday, Wilmington reaches 71 under mostly sunny skies. Saturday and Sunday push into the upper 70s, ideal for early Halloween decorating or outdoor events.
Looking ahead, Monday and Tuesday stay warm, with highs near 80 and plenty of sun. This pattern offers a stretch of classic fall weather after today’s advisory ends.
Residents are encouraged to monitor local tide levels and prepare for possible travel delays this evening. After the advisory, conditions improve, offering one of the best weekends so far this October.
