Blizzard

“In the United States, the National Weather Service defines a blizzard as sustained 35 mph (56 km/h) winds which lead to blowing snow and cause visibilities of ¼ mile or less, lasting for at least 3 hours. Temperature is not taken into consideration when issuing a blizzard warning, but the nature of these storms is such that cold air is often present when the other criteria are met.[1] . Temperatures are generally below 0 degrees F.”
