Even in a city famous for blizzards that roar off Lake Erie shared with Canada, this one stunned Buffalo locals. It even featured the unusual phenomenon of "thundersnow" -- in which snow falls instead of rain during a storm. Another forecaster said he was at a loss of words to describe it.
Many areas south of Buffalo, which is near Niagara Falls, were socked with up to 1.8 meters in less than 24 hours. The snowfall was expected to continue.
He added that three people died from apparent heart attacks while shoveling snow, and another while pushing a trapped car.
The blizzard was weirdly localised.
While 1.5 meters of snow was reported at a site just southeast of the town of Lancaster, only 10 kilometres to the northwest just 10 centimetres fell at Buffalo Niagara International Airport, the Buffalo News newspaper said.
There's no meteorological term for the phenomenon that generated a wall of clouds and churned out such a stunning amount of snow, said Dave Zaff of the National Weather Service in Buffalo, the paper said.
