What a blizzard warning means
A blizzard warning is about wind and visibility, not snowfall totals. It is issued when sustained winds or frequent gusts of 35 mph or more combine with falling or blowing snow to reduce visibility to under a quarter mile for at least three hours. Whiteout conditions can strand drivers in minutes, and wind chills during blizzards are often dangerous.
