A recent nasty storm in Antarctica gave Mt. Washington's world record wind speed a run for its money...
"Wind gusts reached greater-than-hurricane strength at Black Island, with speeds clocked at 193 knots (211 mph) and sustained winds at 99 knots (114 mph). The all-time surface wind-speed record is 231 mph, recorded during an April windstorm in 1934 at the Mount Washington Observatory."
