A heavy snowstorm has hit the northeastern United States. For the region around the city of Buffalo in western New York state, the National Weather Service on Friday predicted “historic snowfall of more than four feet,” more than 4 feet. The weather service warned of “near-zero visibility, near-impossible travel, damage to infrastructure and paralysis of the hardest-hit communities.”

A state of emergency was declared for eleven counties. Erie County officials around Buffalo imposed a driving ban.

The governor of the state of New York, Kathy Hochul, had already warned of an “extreme weather event” the day before. “That means it’s dangerous. It also means it’s life-threatening.” People should prepare “for the worst” and stay home if possible.
