Blizzard conditions are characterized by strong winds, heavy snowfall, and reduced visibility, making them a significant threat to safety. Understanding what constitutes a blizzard and how to prepare for one is crucial for minimizing risks.
A blizzard is a long-lasting combination of snow whipped by high winds that can be dangerous for those caught out in the open. According to the National Weather Service, blizzard conditions are categorized by meeting all of the following criteria:
- Blowing and/or falling snow
- Winds of at least 35 mph
- A reduction of visibility to a quarter mile or less
- All those conditions persist for at least 3 hours
Sometimes, significant accumulating snow alone without much wind may be incorrectly referred to as a blizzard. However, it’s the combination of snow and high winds that produces the classic whiteout conditions you may have either personally experienced or seen video or photos of.
Snow doesn’t have to be falling: Sometimes, a blizzard happens even after a storm’s snow is over. If snow on the ground is fluffy, strong winds can whip it into areas of reduced visibility known as ground blizzards. This is common in the middle of winter in rural areas of the Plains, and can lead to a sudden reduction in visibility and the buildup of drifts on roads that don’t have snow fences.
When and where they happen most: Blizzards can happen in much of the country where snow can fall in winter, including the Northeast, Midwest, and Mountain West. But according to a 2017 study, they’re by far most common in the Northern Plains, including North Dakota, South Dakota, and northwestern Minnesota.
The rest of Minnesota, much of Iowa, Nebraska, northwest Kansas, eastern Colorado, far eastern Wyoming, and parts of eastern Montana have at least a one-in-three chance of a blizzard each year, carving out the rest of the Plains blizzard alley.
Why They’re Dangerous
Whiteout conditions can be disorienting, especially in rural, outlying areas at night. With visibility so restricted, you may not be able to see familiar landmarks, even on roads you use frequently. Plow crews may not be able to clear roads fast enough, particularly secondary roads. Roads could drift shut with snow that may trap your vehicle.
Even major roads and interstates can become impassable if there’s an accident and dozens, if not hundreds, of vehicles get stuck behind the wreck for hours in bitterly cold conditions.
