Philadelphia, PA – Triple-digit heat indices are slamming Pennsylvania, New Jersey, and Delaware, with the most dangerous conditions expected Tuesday as “feels-like” temperatures soar past 110° in some areas.
According to the National Weather Service in Mount Holly, maximum heat index values will peak Tuesday afternoon across the tri-state region. Georgetown, DE, could feel as hot as 110°, while Philadelphia, Vineland, Trenton, and Chestertown may all experience indexes between 105° and 108°. A gradual decrease begins Wednesday, but relief won’t be noticeable until Thursday or Friday.
The oppressive heat is triggering health concerns, particularly for vulnerable populations. Residents are urged to stay indoors, hydrate frequently, and use cooling centers where available. The NWS recommends avoiding strenuous activity during peak afternoon hours, dressing in lightweight clothing, and checking on elderly neighbors.
In Pennsylvania, Allentown and Reading are expected to hit 106° and 107° respectively. In New Jersey, Trenton and Toms River will see similarly intense heat. Across Delaware, Wilmington’s index could reach 106° by mid-afternoon.
Officials warn that power outages could increase the risk of heat illness. If you lose power, go to a basement or public facility with AC, and take cold showers to reduce core temperature.
Heat advisories remain in effect through Wednesday, with updated guidance expected by midweek.
