Early-Season Nor’easter Slams the Northeast Weekend of September 25-27, 2026
By Drooid · · How we work
Core Event
A rapidly deepening low moved north along the Atlantic coast on Friday, September 25. Forecasts called for storm-force winds, heavy rain and coastal flooding from the Mid-Atlantic to New England. Peak gusts of 60 mph were projected for Cape Cod, Martha’s Vineyard, Nantucket and parts of Boston, with 50-55 mph around Boston and 35-40 mph inland. Rainfall totals of 2-3 inches were expected for New York City, 4-6 inches along the Massachusetts coast and up to 8 inches in some outlets. Coastal flood warnings and high-wind advisories covered the I-95 corridor, with the greatest flooding risk tied to high-tide cycles on Friday night and Saturday morning.
Background & Context
Nor’easters draw winds from the northeast and are most common September-April. This storm arrived unusually early, when many trees still bore leaves, raising the risk of wind-driven limb loss and outages. Although an El Niño was developing, the nor’easter’s impacts were driven by the coastal low rather than tropical systems.
Data & Statistics
- Wind gusts: 60 mph on Cape Cod, Martha’s Vineyard, Nantucket; 50-55 mph around Boston; 35-40 mph inland.
- Rainfall: 4-6 inches projected for the South Shore, Cape Cod and Martha’s Vineyard; 2-3 inches for New York City; some forecasts cited up to 8 inches in southeastern Massachusetts.
- Coastal flooding: Moderate to major flooding expected in low-lying areas of Long Island, the Jersey Shore and coastal New York City neighborhoods; water levels 1-3 ft above high tide.
- Wave heights: 7-12 ft along the New Hampshire coast; 15-18 ft along the Jersey Shore and Outer Banks.
Impact
The storm forced cancellation or postponement of several public events, including the Global Citizen Festival in Central Park and the All Things Go festival in Queens. The Boston Red Sox moved a Sunday game to Friday. Ferry services to Cape Cod islands and Block Island were suspended, and portions of North Carolina’s Highway 12 were closed due to overwash. Power utilities readied crews for outages, and state emergency operations centers were activated in New Jersey and New York.
Official Statements & Responses
Governor Dan McKee noted that the Rhode Island Emergency Management Agency and the Department of Transportation were securing roads and deploying crews. New York City officials issued a travel advisory beginning at 2 p.m. on September 25, urging commuters to allow extra time and avoid low-lying routes. Massachusetts officials warned that the timing before leaf fall would exacerbate tree-related damage.
On-the-Ground Reports
Residents on Cape Cod and Martha’s Vineyard prepared for boat-line closures. In Brooklyn, restaurant owner Dimitrios Karousis installed storm drains to channel water directly to the ocean. Long Island businesses readied sandbags and moved equipment off the floor. On the Jersey Shore, George Gorman noted dune-reinforcement work reflecting lessons from Superstorm Sandy.
Conflicting Reports & Gaps
Rainfall projections differ: the Weather Channel and AccuWeather cited up to 8 inches for southeastern Massachusetts, while the National Weather Service forecast 4-6 inches. Wind gust estimates also vary, with some forecasts mentioning gusts up to 65 mph in Montauk, New York, though most agencies reported a maximum of 60 mph. Precise timing of the storm’s peak impact remains uncertain as models adjust the low’s track.
