Flash flooding across coastal Connecticut, New York, and New Jersey disrupted nearly every way people move through the Northeast on Sunday: flights were delayed, train service was interrupted, roads went underwater, and one airport terminal temporarily closed.
The immediate storm has moved on, and Monday’s forecast is much calmer. But travelers heading through the New York–Boston corridor should still check their plans before leaving home because transportation systems can take longer to recover than the weather itself.
Editor’s note: This article was last verified early Monday, September 14, 2026. Conditions can change quickly, so confirm your flight or train directly with the carrier before departure.
What happened across the Northeast
Heavy rain fell at rates of up to 2 inches per hour Sunday, with totals of 6 to 7 inches reported in parts of coastal Connecticut, according to Associated Press reporting based on National Weather Service data.
The flooding was severe enough to require water rescues. Westport officials reported 13 rescues from submerged vehicles, while emergency crews in Paterson, New Jersey, rescued about 20 people from floodwaters. Officials continued warning people not to drive around barricades or into flooded streets.
For travelers, the impact extended well beyond local roads. Metro-North and Amtrak reported delays and cancellations. Tweed New Haven Airport closed its departures terminal during the flooding, and weather-related ground stops affected major New York airports. By Sunday afternoon, nearly 4,000 U.S. flights had been delayed, with Boston Logan, John F. Kennedy, and LaGuardia among the airports feeling the storm’s effects.
New York–Boston train travel took a major hit
Amtrak suspended service between New York and Boston Sunday evening after storm debris and high tides affected the tracks near New Haven. The interruption also affected travelers trying to connect through Connecticut on the busy Northeast Corridor.
The problem was not simply a late train. When a segment of this corridor is blocked, trains and crews can end up out of position, which may create later schedule changes even after the track reopens. Travelers booked Monday should check the Amtrak service alerts page and their reservation in the Amtrak app before going to the station.
If your train is canceled or significantly changed, review the fare conditions attached to your ticket before rebooking. Amtrak’s refund and change options vary by fare type, and an agent may be able to help when a disruption is tied to service conditions rather than a voluntary change.
Flight delays may follow travelers beyond New York
A storm centered in the Northeast can create delays across the country because aircraft and crews scheduled through New York or Boston may operate several more flights later in the day. That means a traveler in Florida, Chicago, or California can feel the effects even when the weather at the departure airport is clear.
Before leaving for the airport, check the airline’s app and the FAA’s live airport status information. Early Monday, the FAA was not showing active ground stops or ground-delay programs at the major Northeast hubs, an encouraging sign that the immediate air traffic restrictions had eased. Individual flights can still be delayed or canceled as airlines reposition crews and planes.
If your flight is canceled or significantly changed and you decide not to accept the alternative offered, the U.S. Department of Transportation says you are entitled to a refund. The department’s airline refund guidance explains the rule and what counts as a significant change.
Monday’s weather is improving, but the cleanup matters
The Monday forecast for the New York area calls for drier, cooler conditions, with gusty north winds but no repeat of Sunday’s torrential rain. That reduces the chance of a new weather-driven shutdown, but it does not instantly clear debris, reopen flooded roads, or restore every disrupted schedule.
Airport and rail travelers should also allow extra time for ground transportation. A train may be running while a nearby road, station entrance, parking area, or local transit connection is still affected. In coastal Connecticut especially, check municipal alerts if your route passes through a community that reported flooding.
What travelers should do before leaving
- Check the exact flight or train number. A systemwide “normal” status does not guarantee that your specific trip is on time.
- Look at the whole itinerary. If you have a connection, check the status of the inbound aircraft or train segment when that information is available.
- Use the carrier’s official app or website. Third-party alerts can lag behind a cancellation, gate change, or rebooking.
- Leave extra time for the trip to the terminal. Local flooding and cleanup can affect roads even after rail and airport operations resume.
- Document your disruption. Save cancellation notices, receipts, and screenshots in case you need to request a refund, reimbursement, or travel-insurance coverage.
- Do not drive through floodwater. If a road is barricaded or covered, turn around and use a verified alternate route.
The good news is that the worst of Sunday’s weather is over and Monday’s forecast is considerably calmer. The smart move is still to verify every leg of the trip before walking out the door. A two-minute check can save a much longer wait at the airport or station.
