Many U.S. residents are facing another night of below-freezing temperatures and no electricity after a massive winter storm dumped more snow in Northeast and left parts of the South coated in ice. The colossal storm halted air and road traffic in many areas and sent temperatures plunging. At least 26 deaths were reported in states hit by the winter weather. As the work week began, the heaviest snow fell from New York northward into New England. That's after heavy ice snapped branches and power lines in the South, leaving hundreds of thousands of homes and businesses without electricity. Arctic air was spreading in behind the storm and some communities in New York saw record-breaking subzero temperatures.
A surge of arctic air is bringing strong winds, heavy snow and frigid temperatures to the Great Lakes and Northeast, a day after a bomb cyclone that hit the northern U.S. Tens of thousands of customers were without power early Tuesday, with Michigan hardest hit. The National Weather Service predicts snow squalls and gusty winds for the Eastern U.S. New York's governor warned of whiteout conditions in parts of the state. In Michigan, snow piled up quickly on Monday, and high waves on Lake Superior sent cargo ships into harbors for shelter.

A strengthening bomb cyclone is barreling across the northern United States, unleashing severe winter weather in the Midwest and aiming at the East Coast. The storm brought blizzard conditions, treacherous travel and widespread power outages Monday across the Plains and Great Lakes. Forecasters say the storm intensified rapidly, meeting the criteria of what's known as a bomb cyclone. The sharp cold front left parts of the central U.S. waking up to temperatures 50 degrees colder than the day before. The National Weather Service had warned of whiteout conditions beginning Sunday that could make travel impossible in some areas.
California officials are urging holiday travelers to avoid the roads on Christmas Eve and Christmas Day. A series of powerful winter storms is expected to douse California with relentless rain, heavy winds, and snow this week. Much of the state will see heavy rains and gusts that could lead to flooding, mudslides and rock slides. The Sacramento Valley and San Francisco Bay Area are under flood and high wind warnings through Friday. The Sierra Nevada will see heavy snow and strong winds, making travel nearly impossible. Southern California could see its wettest Christmas in years and warned about mudslides and debris flows. Some 380 particularly vulnerable households were ordered to leave.

Atmospheric rivers are long and relatively narrow bands of water vapor that form over an ocean and flow through the sky. They carry moisture from the tropics to northern and southern latitudes, and can dump heavy rains or snow over land. According to the National Oceanic and Atmospheric Administration, they occur globally but are especially significant on the West Coast of the United States, where they create 30% to 50% of annual precipitation and are vital to water supplies but also can cause storms that produce flooding and mudslides.
