Update: January 14, 2019 at 9:30 a.m. ET

Winter Storm Gia forced approximately 1,500 flight cancellations across the U.S. over the weekend but those issues are beginning to clear up Monday morning, with flight-tracking website FlightAware.com reporting just 170 cancellations and 450 delays within, into or out of the U.S. as of 9:30 a.m. ET.

A majority of those headaches are being felt in the Washington, D.C. area, with Reagan National and Washington Dulles airports combining for 82 flight cancellations.

Winter Storm Gia is causing travel headaches from the Midwest to the Northeast U.S. this weekend, dumping snow and ice on roads and runways.

Gia walloped parts of the Midwest Friday and Saturday, causing nearly 500 car accidents in Missouri alone, according to Weather.com. The storm even caused an American Airlines flight to slide off of the runway at Missouri’s Columbia Regional Airport Friday. Fortunately, no injuries were reported.
