As of 9 a.m. Monday, two of Chicago's major airports, Chicago Midway International Airport and O'Hare International Airport, are facing more than 40 delays, according to the Chicago Department of Aviation.

Officials at two major Washington, D.C., area airports, Ronald Reagan National Airport and Washington Dulles International Airport, also advised travelers that some flights would be impacted by the storm.

Heavy snow falling from 2 inches to 4 inches an hour was forecast for Monday in the Eastern region, the National Weather Service said.

Much of the region could see blizzard-like conditions, with a foot to 18 inches of snow.

American Airlines canceled about 245 flights Monday due to the storm, a spokesperson told FOX Business. Meanwhile, Delta canceled 340 flights "with the vast majority already being rebooked for other flights," a spokesperson said.

"Teams are monitoring the storm and airport conditions and we'll share a revised number later in the day if more cancels are necessary," Delta said.

Southwest canceled fewer than 200 flights but is "monitoring the winter storm and making adjustments to the flight schedule as necessary."

Chicago got almost 7 inches of snow by Sunday morning, leading to the cancellation of a couple of hundred flights at the city’s two airports. In Wisconsin, snow depths in some counties near Lake Michigan had reached more than 15 inches, and the snow was still falling.

Up to 5 inches of now also hit central Ohio, Washington, D.C., and parts of Virginia. By Sunday afternoon, the snow reached Pennsylvania.
