The Mount Weather Emergency Operations Center is a civilian command facility in the U.S. Commonwealth of Virginia, used as the center of operations for the Federal Emergency Management Agency (FEMA). Also known as the High Point Special Facility (HPSF), its preferred designation since 1991 is "SF".

The facility is a major relocation site for the highest level of civilian and military officials in case of national disaster, playing a major role in continuity of government (per the U.S. Continuity of Operations Plan).

Mount Weather is the location of a control station for the FEMA National Radio System (FNARS), a high frequency radio system connecting most federal public safety agencies and the U.S. military with most of the states. FNARS allows the president to access the Emergency Alert System.

The site was brought into the public eye by The Washington Post, when the government facility was mentioned while reporting on the December 1, 1974, crash into Mount Weather of TWA Flight 514, a Boeing 727 jetliner.

Located in the Blue Ridge Mountains, access to the operations center is available via State Route 601 (also called Blueridge Mountain Road) in Bluemont, Virginia. The facility is located near Berryville, 48 miles (77 km) west of Washington, D.C.

The site was originally opened as a weather station in the late 1800s. It was used as a Civilian Public Service facility (Camp #114) during World War II. At that time there were just two permanent buildings on the site: the administration/dormitory building, and the laboratory. Those buildings still stand, supplemented by many more modern buildings.

The underground facility within Mount Weather, designated "Area B", was completed in 1959. FEMA established training facilities on the mountain's surface ("Area A") in 1979.
