A Heat Advisory remains in effect for northern Delaware and surrounding areas through 8 PM Wednesday, as dangerous heat index values approach 100 degrees.
New Castle County is under the advisory, along with parts of southeastern Pennsylvania and southern New Jersey. The National Weather Service warns that heat index values could reach 98 degrees, with record-breaking temperatures possible through Wednesday afternoon.
“Given the intensity of this early season stretch of heat and humidity, we are not acclimated to it yet,” forecasters warn. The combination of hot temperatures and high humidity significantly increases the risk of heat-related illnesses.
Residents should take immediate precautions: drink plenty of fluids, stay in air-conditioned spaces, avoid prolonged sun exposure, and check on elderly relatives and neighbors who may be more vulnerable to heat stress.
Relief is coming. The Weather Service says showers and thunderstorms are expected to arrive later Wednesday afternoon and evening, which will break this early season heat wave.
The Heat Advisory expires at 8 PM Wednesday. Until then, limit outdoor activities during peak heating hours and never leave children or pets in vehicles, even briefly.
