Flash flooding submerged portions of New Jersey on Monday as Democratic Governor Phil Murphy issued a state of emergency, calling on residents to avoid unnecessary travel and to stay indoors.
Newsweek reached out to the National Weather Service (NWS) via email for comment.
Why It Matters
The declaration marks a critical response to a pattern of increasingly frequent and severe weather pounding the Northeast, including blistering heat waves.
Murphy’s decision to declare the state of emergency enables emergency agencies to deploy resources more rapidly and coordinate across jurisdictions. The call came after the NWS issued multiple flash flood warnings for areas across the state, highlighting the risks posed by sudden heavy rainfall.
Regional emergency declarations are part of a broader trend across the U.S. this summer, as extreme weather has triggered catastrophic flooding in states including Texas and New Mexico.
