How is visibility impacted during a snow event categorized as low drifting snow?

During a snow event categorized as low drifting snow, visibility is significantly impacted, and the correct answer accurately reflects that visibility can become severely restricted. Low drifting snow occurs when snow that has fallen is picked up and blown around by the wind, which can create whiteout conditions where it is difficult to see even a short distance ahead.

While some events might allow visibility to occasionally exceed certain thresholds, such as being above 7 miles, low drifting snow generally implies adverse conditions that would typically lead to poor visibility, often less than a mile, depending on the intensity of the drift and wind conditions.

This insight allows observers to accurately assess and report on visibility during snow events, thereby contributing to safety measures for transportation and activities affected by weather conditions. Other options may suggest stable or higher visibility ranges, which do not align with the typical impacts of low drifting snow on visibility.
