More than seven inches of rain fell in parts of the New York metropolitan region on Sunday, turning roads into waterways, trapping drivers and disrupting rail and air travel before the storm finally moved out.
A preliminary National Weather Service rainfall report measured 7.45 inches in Stamford, Connecticut, by 12:20 p.m. on September 13. The same report logged 6.91 inches in Branford, 5.92 in Fairfield, 4.92 in Paramus, New Jersey, and 4.34 near Rye, New York.
In Westport, Connecticut, the sudden rise was fast enough to strand motorists inside their vehicles. Town officials said emergency crews completed 13 vehicle rescues as floodwater covered streets and forced closures along U.S. 1 and other major routes, according to NBC Connecticut.
Rain fell faster than streets could drain
The worst-hit corridor stretched across coastal Connecticut, Westchester County in New York and northern New Jersey. The Associated Press reported rainfall rates of one to two inches an hour in several places, with the Norwalk-Westport area seeing bursts estimated at three to four inches an hour.
That intensity matters as much as the total. Even a drainage system designed for heavy rain can be overwhelmed when several inches arrive in a short window. Water can then pool beneath bridges, cross highway lanes and rise around vehicles before drivers realize a familiar road has become impassable.
Connecticut’s impacts were especially visible. Floodwater covered part of Interstate 95 in Greenwich during the morning. Westport Fire Chief Nicholas Marsan urged residents to stay home while crews handled stranded motorists, flooded basements, carbon-monoxide alarms and other emergencies.
In Bridgeport, police received roughly 100 flood-related calls Sunday morning, many involving vehicles stuck on inundated roads, CT Insider reported. Firefighters deployed boats to bring residents out of flooded areas. Local officials said numerous roads across Norwalk, Fairfield, Greenwich, North Branford and other communities were closed at different points during the storm.
Trains stopped and an airport terminal closed
The disruption extended beyond local streets. Metro-North and Amtrak service on the New Haven Line was suspended between Norwalk and Bridgeport because of track conditions caused by the rain. Service east of South Norwalk later resumed, although residual delays remained.
Tweed New Haven Airport closed its departures terminal for the rest of Sunday and told departing passengers not to come to the airport until further notice. Arrivals were left subject to real-time conditions.
The storm also forced cancellations beyond transportation. Sunday programming at the Norwalk Oyster Festival was called off, while Connecticut officials closed Sherwood Island State Park in Westport because of the severe weather.
The immediate emergency eased, but hazards remained
All flash-flood warnings issued for Connecticut had expired by Sunday afternoon, and skies began clearing across parts of the region. Authorities nevertheless warned that standing water, damaged roads, downed or low-hanging wires and flooded electrical systems could remain dangerous after the rain ended.
No deaths or serious injuries had been reported in connection with the tri-state flooding as of Sunday evening, according to the AP. That fortunate outcome followed a day of repeated rescues and serves as a reminder of the National Weather Service’s core flood-safety advice: never drive around a barricade or into water covering a roadway.
The full scope of property and infrastructure damage was still being assessed. Sunday’s preliminary rainfall figures may also be refined as additional gauges and official observations are reviewed.
What to watch next
The immediate flood threat diminished as the storm moved away, but transportation agencies and local governments were still working through closures, cleanup and inspections Sunday evening. Travelers should check directly with Metro-North, Amtrak, Tweed New Haven Airport and local transportation departments before setting out.
For residents returning to affected properties, officials advised staying clear of standing water and calling emergency services rather than entering a flooded basement or approaching damaged utilities. The rain may have stopped, but the safest assumption is that hidden hazards can outlast the storm.
