A Heat Advisory remains in effect for New Castle County and surrounding areas until 8 PM Wednesday, as dangerous heat and humidity create potentially life-threatening conditions across Delmarva.
The National Weather Service warns heat index values could climb as high as 98 degrees, with some areas approaching 100 degrees during peak afternoon hours. Record-breaking temperatures are possible through Wednesday.
The advisory covers New Castle County in Delaware, along with portions of southeastern Pennsylvania and southern New Jersey, including Philadelphia, Camden, Gloucester, and Mercer counties.
Meteorologists emphasize this early-season heat wave poses heightened risks since residents haven’t yet acclimated to summer conditions. The combination of intense heat and high humidity significantly increases the danger of heat-related illnesses.
Health officials urge residents to drink plenty of fluids, stay in air-conditioned spaces when possible, and avoid prolonged sun exposure. Check on elderly neighbors and relatives, who face greater health risks during extreme heat events.
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. Stay with TV Delmarva for continued weather updates and safety information throughout this heat event.
