New Jersey residents woke up this Tuesday, July 15, 2025, to a landscape still reeling from the intense weather events of Monday, July 14th. Governor Phil Murphy proactively declared a State of Emergency, effective 8:00 p.m. on Monday, across all 21 counties, citing the pervasive threat of flash flooding, severe thunderstorms, relentless rainfall, and powerful wind gusts. This decisive action, formalized under Executive Order No. 392, underscored the seriousness of the weather system impacting the Garden State.
Governor Murphy’s declaration was issued “out of an abundance of caution,” urging all New Jerseyans to prioritize safety. The message was clear: exercise extreme caution, adhere to all safety guidelines, and, most critically, avoid unnecessary travel. The call to stay off the roads was paramount as conditions deteriorated rapidly, with many areas experiencing significant inundation.
The severe weather, characterized by a slow-moving storm front, brought considerable downpours, gusty winds, and frequent lightning. While the storms were expected to gradually weaken as they moved southeastward overnight, especially after sunset diminished their primary energy source, their impact on Monday, particularly in Northern and Western New Jersey, was substantial. These regions, often more susceptible to intense storm activity due to geographical factors and diurnal instability, felt the brunt of the initial onslaught, experiencing conditions that warranted a severe weather alert.
Throughout the week, New Jersey is expected to remain under the influence of a typical summer pattern: hot, humid, with plenty of sunshine interspersed with the potential for afternoon and evening thunderstorms. While Monday was anticipated to be the most widespread day for storms, the forecast suggests that isolated to scattered showers and thunderstorms will remain a possibility for the remainder of the week. Temperatures are projected to climb, with many areas potentially breaking into the 90s by Thursday and Friday, compounding the humid conditions.
Staying informed during such dynamic weather events is essential for the safety of all residents. The Governor’s office encouraged New Jerseyans to regularly consult official weather resources. For the latest updates, warnings, and safety protocols, residents should frequently visit ready.nj.gov. Additionally, monitoring localized forecasts is crucial, with specific recommendations to consult the U.S. National Weather Service for the New York, N.Y. area (for Northern New Jersey and the New York Metro region) and the U.S. National Weather Service Philadelphia/Mount Holly (for Central and Southern New Jersey).
As we navigate the continued summer weather, understanding these patterns and heeding official advisories becomes paramount.
