Blizzards are severe winter storms that pack a combination of blowing snow and wind resulting in very low visibilities. While heavy snowfalls and severe cold often accompany blizzards, they are not required. Sometimes strong winds pick up snow that has already fallen, creating a blizzard. Officially, the National Weather Service defines a blizzard as large amounts of falling OR blowing snow with winds in excess of 35 mph and visibilities of less than 1/4 of a mile for an extended period of time (greater than 3 hours). When these conditions are expected, the National Weather Service may issue a “Blizzard Warning”. When a less severe, but still dangerous, winter storm is expected a “Winter storm Watch” or “Winter storm Warning” may be issued. A “Winter storm Watch” is issued in advance and means that there is the possibility of a winter storm affecting your area. Keep alert and stay tuned to TV, radio, and other sources of weather information. A “Winter storm Warning” means a winter storm is imminent or already occurring.
