Weather-related deaths climb to 37 as winter maintains icy grip over much of US

There have been at least 37 weather-related deaths across the United States since Sunday as an arctic blast continues to unleash heavy snow and icy temperatures.

There have been at least 37 weather-related deaths across the United States since Sunday, as an arctic blast continues to unleash heavy snow and icy temperatures from coast to coast.

The state with the most fatalities so far was Tennessee, where Nashville got more than 9 inches of snow since Sunday -- nearly twice the annual average. The Tennessee Department of Health confirmed 14 weather-related deaths.

As of Thursday morning, more than 92 million Americans were on alert for cold or snowy weather. Winter storm warnings and winter weather advisories issued by the National Weather Service stretch from Montana all the way to the New Jersey shoreline as a fast-moving storm system takes aim.

While the chilly weather was expected to stick around for most of the Midwest, temperatures won't be quite as low as they were earlier in the week. Still, there was more snow in the forecast for Thursday as a storm system moves from the Plains into the Midwest and Great Lakes regions, potentially creating treacherous road conditions.
