ATLANTA — Hundreds of flights were canceled or delayed Tuesday, one day after powerful storms swept across the eastern half of the country and upended air travel in a cross-section of cities. Travelers have been facing additional jams at airport security checkpoints as a partial government shutdown strains screener staffing.

Mount Arvon, Michigan, saw 39 inches of snow, and Green Bay, Wisconsin, got more than 26 inches, according to the National Weather Service in Green Bay.

The storms also ushered in cold temperatures, with cities in the east 20 to 35 degrees colder than yesterday. Washington D.C., for example, dropped 26 degrees in just 90 minutes on Monday.

The airport disruptions come at an already challenging time for air travel, in part because the shutdown that began Feb. 14 has pressured staffing at some security checkpoints. At the same time, airports are crowded with spring break travelers and fans heading to March Madness games, the annual NCAA men’s and women’s college basketball tournaments.

More than 750 flights scheduled to fly into, out of or within the U.S. have been called off as of early Tuesday, and about 1,300 were delayed, according to flight-tracking site FlightAware.
