A Heat Advisory remains in effect for northern Delaware and surrounding areas through 8 PM Wednesday, as dangerously hot temperatures combined with high humidity create heat index values approaching 100 degrees.
New Castle County is among the areas under the advisory, along with portions of southeastern Pennsylvania and southern New Jersey. The National Weather Service warns that record-setting high temperatures are possible through Wednesday afternoon, with heat indices reaching up to 98 degrees during peak heating hours.
Officials are particularly concerned about this early-season heat wave because residents haven’t yet acclimated to such extreme conditions, potentially increasing the risk of heat-related illnesses.
“Given the intensity of this early season stretch of heat and humidity, impacts could be greater if precautions are not taken,” the Weather Service warned.
Residents should drink plenty of fluids, stay in air-conditioned areas when possible, avoid prolonged sun exposure, and check on elderly relatives and neighbors. Those working outdoors should take frequent breaks in shaded or cool areas.
Relief is expected Wednesday evening when showers and thunderstorms move through the region, breaking the dangerous heat pattern. The Heat Advisory expires at 8 PM Wednesday.
