Snow is pounding parts of western New York state as a potentially historic storm that’s already halted traffic on major roadways threatens to topple trees, damage property and knock out power as temperatures plunge.

Snowfall totals have now reached 4 feet in at least three locations. Orchard Park, where the Buffalo Bills had been scheduled to play their now-relocated NFL game Sunday, had snowfall totals of up to 54 inches by Friday afternoon.

Blasdell, about 8 miles south of Buffalo, has received 48 inches of snow, including six inches in the hour between 1 p.m. and 2 p.m. Elma, just southeast of Buffalo also has see 48 inches since the storm rolled in.

Two Erie County residents have died after suffering cardiac events related to shoveling or blowing snow, County Executive Mark Poloncarz announced.

“We send our deepest sympathies and remind all that this snow is very heavy and dangerous,” Poloncarz tweeted.
