Overview

On Sunday, October 20, 2019, a strong storm brought heavy snow to the Black Hills, with a mix of rain and snow to the foothills. Note how the snow cover (red in image below) is strongly confined to the Black Hills and other higher terrain areas to the northwest. Travel became difficult in parts of the northern Black Hills per the webcam images below. The storm also produced very strong winds, with gusts of 60 to 70 mph in locations. In addition, an unofficial gust of 83 mph was reported 1 mile east-southeast of Custer at 509 pm MDT.
