Snow has not totally stopped the U.S. mail, but it is forcing carriers into an unusual situation: Sunday deliveries.

Stuck between a backlog of mail caused by Thursday’s storm and an expected 10 to 12 inches of snow on Monday, the U.S. Postal Service will be making deliveries today in the Kansas City area, including in Lawrence and Leavenworth.

The press release stated that today was the best day for carriers to take advantage of clear streets.

The postal service asked that to help keep carriers safe customers “clear as much snow as possible from walkways, steps, porches and from around rural-type and cluster mailboxes.”
