As millions of Americans hunker down for the winter storm, 19 states and Washington, D.C., have declared states of emergency.

Heavy snow fell in more than a dozen states from New Mexico to Maine. Bonita Lake, New Mexico, an area in the south-central part of the state, received 31 inches of snow over the weekend, the most of any area in the United States, according to the preliminary data.

Winter storm warnings and weather advisories from the NWS span Alaska, Michigan, New York, and Indiana as of early Tuesday.

On Sunday, millions from New Mexico to the Northeast saw impacts from Winter Storm Fern. Thick layers of ice remain on the ground and power lines, and outages across the South skyrocketed as a result. The storm has claimed the lives of two men in Louisiana. Officials there confirm they both died of hypothermia.

A woman in Norwood, Massachusetts was hit and killed by a snow plow truck while walking with her husband in an MBTA parking lot during Sunday's winter storm.
