Late-Season Storm Brings Heavy Snow to Northeast US, Eastern Canada

A late-season winter storm is poised to deliver heavy snow across parts of the northeastern United States and eastern Canada starting Sunday, March 22, 2026, just days after the official start of spring, prompting widespread weather warnings and travel advisories.

The system will first impact northern New England and Quebec on Sunday, with snowfall rates reaching up to two centimeters per hour in areas around Montreal, Monteregie, Drummondville, and Estrie, according to Environment Canada. Accumulations of nearly 10 centimeters are forecast there by Sunday evening. In northern New England, winter storm warnings cover central New Hampshire and Maine through early Monday, where up to eight inches of snow could fall in higher terrain. Winter weather advisories extend to parts of New Hampshire, Maine, and Vermont until midnight Sunday, expecting three to six inches of snow and potential ice accumulations.

As the storm tracks eastward, it will bring 10 to 15 centimeters of heavy, wet snow to much of Nova Scotia beginning late Sunday afternoon, affecting regions from the southwestern shore near Digby to Halifax counties. The heaviest bands are anticipated Sunday evening into Monday...
