Blizzard vs Snowstorm: What’s The Difference?
For travelers and commuters navigating the winter wonderland, distinguishing between a blizzard and a snowstorm is more than just semantics—it's a matter of safety and planning. Whether you're hitting the slopes or simply trying to get to work, understanding the specific challenges posed by each type of storm can make all the difference in your journey. This article will guide you through the key differences between blizzards and snowstorms, providing insights that will help you make informed decisions and stay safe on the road or in the air during the winter months.
What Is a Blizzard?
A blizzard is a severe winter storm characterized by strong sustained winds of at least 35 miles per hour (56 kilometers per hour) and heavy snowfall that reduces visibility to a quarter mile or less for a prolonged period, typically three hours or more. Unlike a regular snowstorm, a blizzard's defining feature is not just the amount of snow but the combination of intense winds and reduced visibility, which can create whiteout conditions and make travel extremely dangerous. These storms can lead to significant snowdrifts, disrupt transportation, and pose serious risks to safety and infrastructure. Understanding the dynamics of a blizzard is crucial for effective preparation and response, especially in regions prone to such extreme weather events.
What Is a Snowstorm?
A snowstorm is a weather event characterized by snowfall that can vary in intensity and duration, often accompanied by cold temperatures. Unlike blizzards, snowstorms do not necessarily involve strong winds or severely reduced visibility, although they can still lead to significant snow accumulation and impact daily activities. Snowstorms can range from light flurries to heavy snowfalls that blanket regions in a thick layer of snow, affecting transportation, infrastructure, and daily life. While they may not possess the ferocity of a blizzard, snowstorms still require preparation and caution, particularly in areas where they are frequent, to ensure safety and minimize disruption. Understanding the nature of snowstorms helps individuals and communities anticipate and manage the challenges they present during winter.
Blizzard vs Snowstorm: What’s The Difference?
Intensity and Wind Speed
-
Blizzard:
- Characterized by strong sustained winds of at least 35 miles per hour (56 kilometers per hour).
- The intense winds create blowing snow and whiteout conditions.
-
Snowstorm:
- It may involve light to moderate winds but not necessarily strong enough to cause severe visibility issues.
- Focuses more on the amount of snowfall rather than wind intensity.
Visibility
-
Blizzard:
- Visibility is reduced to a quarter mile or less due to blowing snow.
- Whiteout conditions are common, making travel extremely hazardous.
-
Snowstorm:
- Visibility can be reduced, but typically not to the extent seen in blizzards.
- Snowfall can still impact travel, but conditions are generally less severe.
Duration
-
Blizzard:
- Conditions must persist for at least three hours to be classified as a blizzard.
- The prolonged nature of the storm increases its potential impact on infrastructure and safety.
-
Snowstorm:
- Duration can vary widely, from brief snow showers to extended periods of snowfall.
- The impact is often more related to snow accumulation than duration.
Impact and Preparation
-
Blizzard:
- Requires significant preparation due to potential power outages, road closures, and safety risks.
- Emergency protocols and supplies are crucial for those in affected areas.
-
Snowstorm:
- While preparation is still important, the focus is more on managing snow accumulation and maintaining safe travel conditions.
- Less likely to cause widespread disruptions compared to blizzards.

How Much Snow Is Considered a Blizzard?
Interestingly, the classification of a blizzard is not directly tied to the amount of snowfall but rather to the combination of wind speed and visibility conditions. For a storm to be officially deemed a blizzard, it must feature sustained winds of at least 35 miles per hour (56 kilometers per hour) and visibility reduced to a quarter mile or less due to blowing or falling snow, persisting for a minimum of three hours. While heavy snowfall often accompanies blizzards, the fierce winds, and resulting whiteout conditions primarily define this severe weather event. Therefore, a blizzard can occur with varying amounts of snow, emphasizing the importance of wind and visibility over mere snow accumulation in its classification.
Which One Is More Dangerous and Why?
Blizzards are generally considered more dangerous than snowstorms due to their severe wind conditions and drastically reduced visibility, which can lead to life-threatening situations. The combination of strong winds, often exceeding 35 miles per hour, and whiteout conditions can create a disorienting environment, making travel extremely hazardous and increasing the risk of accidents. Additionally, blizzards can cause significant snowdrifts, obstructing roads and access to emergency services, while also posing a threat to infrastructure through potential power outages and structural damage. The prolonged nature of blizzards, lasting at least three hours, exacerbates these dangers, requiring more extensive preparation and emergency response efforts compared to typical snowstorms, which primarily involve managing snow accumulation and maintaining safe travel conditions.
How To Stay Safe During a Blizzard or Snowstorm
Preparing Your Home
Ensuring your home is well-prepared for a blizzard or snowstorm is crucial for safety and comfort. Start by insulating your home to retain heat and prevent drafts, which can help maintain a stable indoor temperature during power outages. Check that your heating system is functioning efficiently and have backup heating options, such as a wood stove or portable heater, ready. It's also wise to weatherproof doors and windows to minimize heat loss. Keep a supply of rock salt or sand to manage icy walkways and driveways, reducing the risk of slips and falls. Additionally, ensure that smoke and carbon monoxide detectors are working properly, as these devices are vital when using alternative heating sources.
Stocking Survival Food and Emergency Kits
Having a well-stocked supply of survival food and emergency kits is essential during severe winter weather. Aim to have at least a three-day supply of non-perishable food items, such as canned goods, dried fruits, nuts, and energy bars, which do not require cooking. Ensure you have a manual can opener and bottled water, with at least one gallon per person per day. Your emergency kit should include flashlights, extra batteries, a first-aid kit, necessary medications, and a battery-powered or hand-crank radio to stay informed about weather updates. Additionally, include blankets, warm clothing, and a multi-tool for various needs. These preparations can make a significant difference in comfort and safety during extended periods of isolation.
Staying Safe Outdoors
If you must venture outside during a blizzard or snowstorm, prioritize safety by dressing in layers of warm, waterproof clothing, including hats, gloves, and boots with good traction. Avoid overexertion when shoveling snow, as this can lead to exhaustion or heart-related issues. It's crucial to stay aware of your surroundings to avoid getting lost in whiteout conditions. If driving is necessary, ensure your vehicle is equipped with an emergency kit, including blankets, food, water, and a shovel. Keep your gas tank full to prevent fuel line freeze-up, and inform someone of your travel plans and expected arrival time. Taking these precautions can minimize risks and ensure your safety during severe winter weather.
Conclusion
For those living in snow-prone regions, distinguishing between blizzards and snowstorms is more than an academic exercise—it's a critical component of effective winter preparedness. By understanding the specific challenges posed by each type of storm, homeowners and residents can take proactive measures to protect their homes and families. This awareness leads to better planning, from stocking emergency supplies to reinforcing home insulation, ultimately ensuring greater safety and resilience during the harshest winter conditions.
