The number of storms with readings below 53.0 increases quickly. Having significance when the difference between two storms is about three Point apart very gray, and 1.0 point quite uncertain. Readings for Pre-ASOS (pre 1995-1996) events, to make rankings of just 0.1 There's enough varianceįrom the mean peak gust for each storm, and uncertainty in the maximum wind Stations, a difference of six mph equals a full point. Only the top three-The Columbus Day Storm, the Inauguration Day Storm,Īnd an event on January 15, 1951-are clearly above what appears to be aīackground of 53-57 mph averages for most significant windstorms.
