The May 2025 nor'easter was an unusual and significant late-season nor'easter which impacted much of New England and Atlantic Canada with heavy rain, damaging winds, coastal flooding, and mountain snow. A Miller B nor'easter, the system originated with an area of low pressure in the Ohio Valley before spawning a secondary low over North Carolina. This low moved offshore late on May 21, steadily deepening as it tracked up the East Coast. After making landfalls on Nantucket and Cape Cod in quick succession early on May 23, the system moved into the Gulf of Maine, where it steadily weakened before making a final landfall in far northeastern Maine and dissipating inland over New Brunswick shortly thereafter.
Over 34,000 customers were left without power at the height of the storm late on May 22, primarily in southeastern New England, where rainfall totals reached 5–7 in (130–180 mm) and winds frequently gusted over 50 mph (80 km/h). Many locations experienced record cold daily high temperatures, and significant mountain snow in interior New England resulted in the return of winter conditions to trails just before the busy Memorial Day weekend and the subsequent deaths of two hikers on Mount Katahdin. Damage estimates are currently unavailable for this system.
