During the afternoon and evening of February 21, nearby Monarch Pass experienced sustained winds as high at times as 68 mph, with gusts as high as 76 mph. The next day, the winds were even stronger from the Continental Divide eastward through the foothills above Boulder, Denver, and Colorado Springs, resulting in widespread wind damage in these areas. Wind in excess of 60 mph was commonplace along the Front Range and foothills, with some spots experiencing gusts in excess of 90 mph. Here are some local storm reports and news reports:

Here is a picture of a mountain wave cloud, along with some cumuloform clouds along the ridges, that I took the morning of the 23rd from the west edge of Salida looking toward Monarch Pass.
Early this morning the wind gusted to 58 mph, even around the valley location where I took this picture. The wind subsided for a time during the day, but by the early morning of February 23, the wind in Monarch Pass was sustained as high as 60 mph with gusts as high as 83 mph.
The violent weather continued into the morning of February 23rd, when I-70 was closed in several locations due to wind, snow, and avalanche danger. Low pressure moving directly over the Denver area intensified in the wee hours, resulting in up to 10 inches of wind-driven snow in parts of the Denver area.
