A strong band of heavy rain swept across the U.S. East Coast overnight, triggering flash floods and widespread travel disruptions in New York City and New Jersey.
According to the National Weather Service, all five boroughs of New York City were placed under flash flood warnings as more than two inches of rain fell in one hour—marking the second-wettest hour ever recorded in Central Park. Subway stations were inundated, causing suspended lines and severe delays on the 1, 2, 3, M, and R routes. The Bronx River Parkway, Saw Mill River Parkway and Cross Bronx Expressway were also temporarily closed due to flooding.
New Jersey Governor Phil Murphy declared a state of emergency amid flash floods that stranded vehicles and residents in Scotch Plains, Somerville, North Plainfield, Roselle Park, and other towns. Rescues were reported, particularly in North Plainfield where numerous homes and cars were submerged.
Airport operations were severely impacted. Ground stops were issued at JFK, LaGuardia, Newark Liberty, and Reagan National airports, resulting in hundreds of flight delays and cancellations.
Officials warn that the storm system will linger, with more heavy rain possible along the I‑95 corridor. Residents are advised to avoid travel unless evacuation is ordered, steer clear of flooded roads, and be ready to move to higher ground—especially those living in basement apartments.
Meteorologists predict additional showers and storms through Tuesday and the rest of the week. The NWS rated the flood risk in the I‑95 corridor as Level 3 out of 4, with rainfall rates topping 2–3 inches per hour in isolated areas.
