The National Weather Service describes a blizzard as large amounts of falling, or blowing, snow, with winds in excess of 35 mph and a visibility of less than one-quarter mile for a period of greater than three hours. When these conditions are imminent, a blizzard warning is issued. Traveling by car becomes extremely dangerous, or impossible due to whiteout conditions and blowing snow. Strong winds and cold temperatures can also combine to create dangerous wind chills, which could lead to frostbite and hypothermia.
