What Forecasters Are Saying About the Early Nor'easter

An unusually early coastal storm is taking shape along the U.S. East Coast, with forecasters warning that the first nor'easter of the season could deliver strong winds, heavy rain and rough surf to parts of the Northeast later this week. Coastal areas of New York, New Jersey and Massachusetts are among those being told to prepare for possible disruption, although the storm's exact track remained uncertain as of early Tuesday.

The system could begin to push gusty winds onshore as soon as late in the day Tuesday, according to weather reports that point to a period of deteriorating conditions in the following days. The main concerns are not snow and ice at this time of year, but rather coastal flooding, travel headaches and beach erosion caused by prolonged rough surf.

AccuWeather senior meteorologist Chad Merrill said the storm has the potential to bring soaking rain and gusty winds to coastal zones even if it does not hug the shoreline, while also warning that rough seas could drive tides well above normal. He noted one possible benefit: if the rain reaches far enough north, it could ease the ongoing drought in Maine.

Nor'easters are coastal storms characterized by winds from the northeast, and the National Weather Service says they typically occur between September and April. A late-September system is therefore not unheard of, but it is early in the season and will be watched closely because the storm's track will determine how disruptive it becomes.

Why This Late-September Storm Is Different

What Makes This Storm Different From a Winter Nor'easter

Late-September systems generally pose a different risk set than the snowstorms many people associate with nor'easters. With temperatures still mild, the main hazards cited by forecasters are coastal flooding, rough surf, beach erosion and travel disruption rather than heavy snow or ice. That makes it an early test of autumn preparedness for shore communities in New York, New Jersey and Massachusetts.

The Track Is the Biggest Source of Uncertainty

Meteorologists do not yet know how close the system will come to the coast, and that distance will largely determine whether the region sees moderate inconvenience or more serious flooding. Merrill's comment that the storm can produce soaking rain and gusty winds regardless of how close to the coast it tracks is a reminder that even an offshore path can send meaningful impacts onshore.

The Potential Upside for Maine

One conditionally positive outcome is drought relief in Maine, where ongoing dryness has persisted. The possible benefit is entirely dependent on the storm's circulation pulling enough moisture far enough north, so it should be viewed as a chance rather than a certainty.

What Travelers and Coastal Residents Should Expect

  • Allow extra time for travel in coastal New York, New Jersey and Massachusetts later this week, especially if flooding or wind advisories are issued for your route.
  • Keep away from beaches and shoreline areas when rough surf and above-normal tides are forecast, since erosion and dangerous waves are among the storm's main coastal hazards.
  • Do not count on this system to break the drought in Maine: any relief depends on the storm's final track and how far north the rain reaches.
