A dangerous early-summer heat wave is set to blanket the Mid-Atlantic through Tuesday, with heat index values soaring over 100°F in Pennsylvania, New Jersey, Delaware, and Maryland. This extreme heat has triggered heat advisories for areas from the Poconos to the Eastern Shore.
The National Weather Service in Mount Holly issued the heat advisory, which began on Sunday morning and will continue through Tuesday at 8 p.m.. Areas like Carbon and Monroe counties in Pennsylvania are among the first to experience the extreme heat.
By Monday, the heat will stretch further south through Dover, Georgetown, and Easton, MD, with “feels-like” temperatures hitting 109°F in some spots.
“Tropical Nights” Ahead
Nighttime temperatures will remain in the mid to upper 70s, which means little cooling at night, creating what meteorologists refer to as “tropical nights.” This lack of relief makes it especially hard for residents, particularly those without air conditioning, to cool down. Urban and inland areas are most vulnerable to this intense heat.
Shore Areas Feeling the Heat Too
Even along the New Jersey shore, from Sandy Hook to Cape May, the heat index will reach near 100°F. The coastal areas are not exempt from the sweltering conditions, with increased risks of heat-related illnesses for beachgoers and residents alike.
Health Risks and Safety Tips
Health officials across the region are warning of increased risks for dehydration, heat exhaustion, and heat stroke due to the prolonged heat. Residents are urged to:
Stay hydrated by drinking plenty of water.
Wear light, loose clothing to stay cool.
Avoid outdoor activities, especially during the hottest parts of the day, typically between noon and 4 p.m.
The heat advisory will remain in effect until 8 p.m. Tuesday, though further alerts could be issued if conditions persist.
