What is the difference between blowing and drifting snow?
Blowing snow is wind-driven snow that reduces surface visibility. Blowing snow can be snow falling or snow that has reached the ground, but is picked up and blown by strong winds. Blowing snow is usually accompanied by drifting snow. Drifting snow is an uneven distribution of snowfall/snow depth caused by strong surface winds. Drifting snow may occur during or after snowfall.
