The National Weather Service has issued a Heat Advisory for New Castle County, Delaware, effective from 11 AM Thursday through 8 PM Friday, as dangerous heat and humidity grip the region.
Heat index values are expected to reach up to 104 degrees, creating potentially hazardous conditions for residents across northern Delaware and surrounding areas including Philadelphia, southern New Jersey, and southeastern Pennsylvania.
“Hot temperatures and high humidity may cause heat illnesses,” warns the National Weather Service. The advisory affects millions of people in the Delaware Valley region.
Health officials urge residents to take precautions: drink plenty of fluids, stay in air-conditioned rooms when possible, and avoid prolonged sun exposure. Check on elderly relatives and neighbors, and limit strenuous outdoor activities to early morning or evening hours.
Some relief may come from scattered showers and thunderstorms expected late Thursday and Friday afternoons, though humidity will remain high. A cold front moving through this weekend should bring more comfortable conditions.
If you don’t have air conditioning, call 211 for assistance finding cooling centers. Watch for signs of heat exhaustion including dizziness, nausea, and excessive sweating.
The advisory expires Friday at 8 PM.
