A snowstorm forces the Smithsonian to close at 12:30 p.m. on Thursday, January 22. The Smithsonian is also closed all day on Monday, January 26. This is the first time the Smithsonian had closed because of inclement weather since January 13, 1983. The National Zoological Park is closed for half days on the 22nd and 25th, and all day the 26th. At least two keepers spend the night sleeping in the Antelope House, to tend the animals.
