Coastal Storm Threatens New England with Heavy Rain and Winds

Coastal storm clouds gathering over New England coastline

New England, October 11, 2025

News Summary

A coastal storm system off the Carolinas is set to impact southeastern New England, bringing 3 to 4 inches of rain and wind gusts up to 60 mph from late Sunday. Flash flooding, coastal flooding, and beach erosion are major concerns, particularly for vulnerable areas. Public officials urge residents to prepare for power outages and to secure outdoor belongings as the storm approaches.

Boston — A coastal storm system developing off the Carolinas is expected to strengthen and accelerate up the East Coast. Drenching rain and damaging, gusty winds will begin late Sunday, October 29. The storm is expected to impact much of southern New England through Tuesday, with the heaviest impacts focused on coastal areas.

Key impacts and timing

The storm may bring 3 to 4 inches of rain across parts of southeastern New England from Sunday night through Tuesday. Wind gusts could reach 50 to 60 mph in coastal Massachusetts, New Hampshire, Rhode Island, and the Cape and islands. Gusty winds and pockets of rain will also extend into inland areas. Heavy rain will likely occur Sunday night into Monday morning.

There is a risk of flash flooding, particularly in low-lying areas near shorelines and tidal waterways. Coastal flooding and beach erosion are also possible during high tide (peaking near 4 p.m. Sunday, 5 p.m. Monday, and 6 p.m. Tuesday). Coastal flood watches are already in effect.

Local hotspots and special concerns

Rain will be heaviest over the Cape and Islands, with localized flooding anticipated due to clogged storm drains from falling leaves. Forecasts indicate sustained winds around 20 mph and gusts potentially exceeding 60 mph in vulnerable coastal zones. Localized power outages are possible due to falling trees and branches.

Travelers should prepare for impacts to transportation. Travelers should prepare for possible delays and cancellations at Logan Airport due to storm conditions. Road travel may also be slowed by standing water, downed debris, and reduced visibility during the heaviest rains.

Preparedness and public guidance

Local officials recommend securing Halloween decorations ahead of strong winds. Residents in low-lying and shoreline areas should monitor local advisories, move vehicles out of flood-prone locations when possible, and avoid driving through flooded roadways. Those with outdoor equipment, loose siding, or weak tree limbs should secure or remove them before sustained winds increase.

While the storm will bring significant rainfall, it will not erase long-term deficits. New England’s ongoing drought may see some relief from this storm, although long-term rainfall deficits remain significant.

Forecast drivers and monitoring

The pressure gradient between a developing low-pressure system offshore and a high-pressure area over Eastern Canada is expected to intensify winds across the region. The pressure gradient from a high-pressure system in Eastern Canada could intensify wind speeds. Meteorologists will continue to monitor the storm’s progress and provide updates as conditions evolve.

Short-term conditions

  • Mornings over the weekend are expected to be less chilly, with temperatures rebounding into the low 60s.
  • Forecasts indicate sustained winds around 20 mph and gusts potentially exceeding 60 mph.
  • Gusty winds and pockets of rain will also extend into inland areas.

Public safety note

Emergency responders and utility crews may be called to address downed trees and power lines; residents should prepare for localized power outages are possible due to falling trees and branches.

What to watch

Monitor weather updates for changes to arrival times and intensity. Pay attention to local flood watches and coastal flood watches, take steps to protect property, and plan for travel disruptions. Meteorologists will continue to monitor the storm’s progress and provide updates as conditions evolve.
