Moving snow drifts in southern Manitoba

Moving snow drifts in southern Manitoba



What happened?

On January 20, 2014, brisk winds in southern Manitoba were occurring. It was noted at the Emerson weather station that the snow on the ground went from 29 cm to 42 cm between 16Z and 17Z, and the webcam shows why this was occurring: the wind was causing snow drifts to move quickly enough that the snow depth at any single point would change wildly from hour to hour. The animation from this webcam is presented here.

Here are the observations from about 2 hours before the animation begins to about 2 hours after it ends.
