Tuesday, July 8, 2025, brought severe weather conditions across eastern Pennsylvania and parts of New Jersey, triggering a First Alert due to the combination of dangerous heat and the risk of violent storms.
By mid-afternoon, the heat index soared to between 100°F and 105°F (38°C – 41°C), pushing feels-like temperatures into the triple digits throughout the region. This intense heatwave, combined with a slow-moving cold front, ignited a powerful round of severe thunderstorms that struck between 3 p.m. and 9 p.m. local time.
The primary threats were damaging wind gusts and torrential rain capable of producing flash flooding in low-lying areas. A fallen tree along the tracks forced SEPTA’s West Trenton Line to shut down service, disrupting local transportation.
Tornado warnings were issued across multiple counties in Pennsylvania, including Bucks, Chester, Delaware, Montgomery, and Philadelphia, while parts of New Jersey, such as Burlington, Ocean, and Monmouth, also faced tornado alerts.
This intense summer system brought powerful gusts, localized flooding, and serious public safety concerns throughout the afternoon and evening.
