The winter weather this weekend is causing significant disruptions for holiday travelers across the Northeast and Midwest. Millions of Americans are facing treacherous travel conditions due to a fast-moving storm system that has dumped several inches of snow. Major highways like the I-95 Corridor are heavily impacted, with parts of I-90 eastbound shut down due to accidents. In Michigan, slick roads have caused vehicles to slide into ditches, while Minnesota has reported over 400 crashes, resulting in injuries and one fatality. Airports are also experiencing disruptions, with United Airlines adding 500 flights per day to accommodate the increased demand, yet many travelers are still caught off guard by cancellations. Travelers are advised to check flight statuses and allow extra time for airport journeys. For those driving, it's recommended to start early in the morning or late in the evening to avoid peak traffic times, particularly between 4 PM and 8 PM. The forecast predicts continued cold weather in the East, with another storm expected to hit the Pacific Northwest and move eastward by December 23rd, potentially affecting cities like Detroit, Green Bay, Boston, New York, and Philadelphia by Christmas Eve. This could lead to a white Christmas in some areas, depending on snowfall amounts.
