Nor'easter brings record rainfall to Massachusetts and Maine

A slow-moving nor’easter moving through the East Coast from September 26 to September 29, 2026, brought heavy rainfall, high winds, and coastal flooding to parts of the United States.

At the summit of Great Blue Hill in eastern Massachusetts, the storm produced 5.15 inches of rain on Sunday, September 27. This more than doubled the previous daily record of 2.26 inches set in 1962. The storm also produced a 58 mph wind gust on Saturday, breaking a record that had stood since 1977.

In Maine, the National Weather Service reported significant precipitation across several counties. Cumberland County saw high totals, with South Portland recording 4.21 inches. York County also experienced heavy downpours, with Biddeford registering 3.91 inches. While southern and western Maine saw substantial rainfall, northern and eastern regions, such as Aroostook County, recorded much lower amounts.
