Why are blizzards dangerous? Blizzards are fierce snowstorms known for their powerful winds and limited visibility.

With their biting winds and swirling snow, these winter storms know how to command respect and attention.

In reality, this awe-inspiring phenomenon challenges human fortitude and infrastructure in so many ways. So, why are blizzards so dangerous?

Blizzards are dangerous because of strong winds, heavy snowfall, and frigid temperatures, causing flight cancellations, road closures, and more. 

What Causes Blizzards?

the causes blizzards

Blizzards usually happen when a frigid air mass from the Arctic region clashes with a balmy, humid air mass from lower latitudes.

As the toasty air ascends above the chilly air, it chills and transforms into droplets, creating clouds and rainfall.

The freezing temperatures result in snowfall, while the strong winds create blinding whiteouts by swirling the snow. 

The Immediate Dangers of Blizzards

the dangers of blizzards

The snowstorms are fueled by the combination of freezing temperatures, resulting in conditions perfect for hypothermia and frostbite.

Compounding the peril is the swift and fierce snowfall, accumulating at a rapid rate of multiple inches per hour. This quickly obstructs sight and engulfs roads and buildings.

But what sends shivers down the spine is the relentless gusts of wind that surpass a certain limit. All this combines to make blizzards truly dangerous.

Fact: A lake effect blizzard is a rare snowstorm characterized by rapid snowfall, exceeding 2-3 inches.

Moreover, blizzards have the power to cause significant disruptions to air travel, resulting in the cancellation or delay of numerous flights during severe snowstorms.

Fact: Over 1,200 car accidents and multiple fatalities were caused by blizzards in the US in 2019. 

Threat to Human Safety

blizzards are threat to human safety

Blizzards pose a significant threat to human well-being, mainly because of the severe conditions they create. For instance: 


It is a dangerous condition triggered by extended exposure to cold. It poses a significant threat during blizzards, as freezing temperatures can quickly drain body heat


Frostbite is a serious concern as it can cause long-lasting damage or even amputation due to the freezing of the skin and underlying tissues.


Blizzards with limited visibility heighten the risk of accidents, such as vehicle collisions and pedestrian incidents.

The biting cold and limited visibility during blizzards can be extremely dangerous, so it is crucial to:

  • Stay updated
  • Avoid unnecessary travel
  • Take necessary precautions to stay safe
Fact: Ground blizzard winter snowstorms are driven by strong winds and reduced visibility, leading to significant travel disruptions. 

 Accumulation and Structural Damage
