Anniversary of Mount Washington’s 231 mph Wind on April 12

On April 12, 1934, Mount Washington recorded a record 231 mph wind. The next year, nature delivered a runner-up as a hurricane hit the Florida Keys with 200-mile-an-hour gusts. For comparison, winds in a tornado are estimated to be 300 miles an hour. Chicago is known as the windy city. But its average yearly wind speed of a little over 10 miles an hour is behind Cheyenne, Wyoming, at nearly 13, and several cities over 12 miles an hour, including Boston; Great Falls, Montana; and Oklahoma City.
