On February 1, 2020, residents of central Montana witnessed one of the worst dust storms the area has experienced in recent years. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image of the storm around Great Falls.
The dust was stirred up by wind gusts of more than 110 kilometers (70 miles) per hour; they also fanned smoke and debris from a fire. As visibility in the area dropped to zero, the blowing dust halted traffic and caused accidents on a local highway, which was subsequently closed.
