Stormy weather across the northeast United States disrupted travel and shut down the federal government Tuesday.

At least an inch of snow is expected to fall on a stretch from Washington, D.C. to Boston — with closer to 4 inches in New York City — and a winter weather advisory was issued from New York to Alabama. More than 790 flights were already canceled by Tuesday morning.

The federal Office of Personnel Management said on its website that federal offices in the Washington area are closed for all non-emergency employees. A federal hearing on the July 6 crash of Asiana Airlines flight in San Francisco was delayed as a result of the weather.

The snowstorms — expected to let up in New York and Washington by the evening — follow days of wintery weather that has impeded commutes and canceled flights across the country.
