In addition, a new storm system will be coming into Seattle on Sunday morning with up to two-tenths of an inch of ice expected. There is a chance that into the afternoon, the storm will shower snow on the area, instead of freezing rain. If that happens, the National Weather Service is expecting up to 2 inches. The system will then move into Colorado Sunday night through Christmas Day, which could affect travel conditions.
The wintry weather may cause some delays and other difficulties — both on the roads and in the skies — during one of the busiest times of the year. According to FlightAware, 660 flights arriving in, departing from or operating within the US were delayed as of 10:30 a.m. on Sunday. The delays were particularly notable in Chicago, New York City and Boston.
