"Blizzards are dangerous winter storms that are a combination of blowing snow and wind, resulting in very low visibility...a storm which contains large amounts of snow or blowing snow, with winds in excess of 35mph, and visibility of less than 1/4 mile for an extended period of time (at least 3 hours)" - National Weather Service
Blizzards and the World
The parts of the world that are most vulnerable to blizzards
1) The upper Midwest and Great Plains tend to be the regions in the US that are most affected by blizzards. Other areas of the world that are affected include Canada, Greenland, Russia, and Eastern Asia.
2) With few trees and other obstructions to reduce wind and blowing snow, these areas become the vulnerable. However, any location that is prone to snowfall can experience a blizzard.
3) e.g. Blizzard of 1888 in Texas to South Dakota
Killed more than 235 people. Dropped more than 40-50inches of snow. Social consequences - people were trapped in their homes for days. Many couldn't leave, many we're separated from their families for extended periods of time.
Utility line repairs, tree removal, and other clean up can cost millions of dollars.
4) Listen carefully to weather forecasts. Chimney needs to be inspected at least once a year. Install smoke detectors and carbon monoxide detectors near fireplaces. All fuel burning equipment should be vented to the outside. Insulate water lines outside the house. Waterproof your home. Weatherstrip all windows and doors.
People in vulnerable locations had their houses built specifically to withstand such storms.
