A torrential winter storm plunged the Colorado snow on the east coast into an air transport mess for the third consecutive day Sunday.
At the national level, approximately 870 flights and 3,171 flights were delayed at 20:40. AND, according to FlightAware Flight Tracking Service. 67 other flights had already been reported Monday.
These problems followed another 460 cancellations on Saturday. Most of this damage comes from the storm, which was canceled at Colorado's central Atlantic airports in the past 72 hours.
The worst-hit airports on Sunday were those serving Washington, DC, where the snow seemed to exceed the 4 to 8 inches originally called by forecasters.
