Death toll rises to 50 as freezing temperatures and heavy snow wallop swaths of U.S.

The huge winter storm that has already killed 50 people in the United States looked set to continue wreaking havoc into Monday with plummeting temperatures and huge snow drifts trapping people inside their homes and snarling travel across the country.

The full brunt of the storm was being felt in western parts of New York, which had become a “warzone,” New York Gov. Kathy Hochul said Sunday, with looting incidents and roads blocked by emergency vehicles.

A "band of heavy lake effect snow" in the Buffalo area was producing two to three inches of hourly snowfall, with accumulations reaching six to 12 inches and as much as one to two feet for Jefferson and northern Lewis counties, the National Weather Service said in its 6:43 a.m. bulletin.

Stretching from the Great Lakes near Canada to the Rio Grande along the Mexican border, the storm has killed at least 50 people as of Monday morning, according to an NBC News tally. The deaths were recorded in 12 states: Colorado, Illinois, Kansas, Kentucky, Michigan, Missouri, Nebraska, New York, Ohio, Oklahoma, Tennessee and Wisconsin.
