Blizzard Warning: What You Need to Know

A blizzard warning is issued by the National Weather Service (NWS) when hazardous winter weather conditions are imminent or occurring. It’s a serious alert, indicating that life-threatening conditions are expected.

Defining a Blizzard

A blizzard isn’t just heavy snowfall. It’s a combination of factors sustained for at least 3 hours:

• Sustained winds or frequent gusts of 35 miles per hour or greater. This creates whiteout conditions and makes it difficult to see.
• Considerable falling or blowing snow. This reduces visibility to ¼ mile or less.

The key takeaway is the *combination* of strong winds, low visibility, and snow. Even without new snowfall, existing snow can be whipped up by high winds, creating a blizzard.

Why Blizzard Warnings Matter

Blizzards pose significant dangers:

• Whiteout conditions: Making travel extremely dangerous, if not impossible. Navigation becomes challenging, and accidents are likely.
• Hypothermia and Frostbite: Prolonged exposure to cold, wind, and snow can rapidly lead to these dangerous conditions.
• Power outages: Heavy snow and strong winds can damage power lines, leaving people without heat or electricity.
• Transportation disruptions: Roads close, flights are canceled, and emergency services may be delayed.

If a Blizzard Warning is Issued:

1. Stay Informed: Monitor local news, weather radio, and the NWS website for updates. Conditions can change rapidly.
2. Stay Home: The safest place to be during a blizzard is indoors. Avoid all unnecessary travel.
3. Prepare Your Home: Ensure you have a supply of food, water, medications, and essential supplies like flashlights and blankets. Have a backup heating source if possible (and use it safely, following manufacturer instructions).
4. Protect Yourself: If you must go outside, dress in layers, cover exposed skin, and tell someone where you’re going and when you expect to return.
5. Conserve Energy: If you experience a power outage, conserve heat by closing off unused rooms and stuffing towels under doors.
6. Check on Neighbors: Especially elderly or vulnerable neighbors who may need assistance.

After the Blizzard

Even after the snow stops, dangers remain. Be cautious of:

• Black ice: Ice can form on roads and sidewalks as temperatures fluctuate.
• Snowdrifts: These can block roads and doorways.
• Weakened structures: Heavy snow can damage roofs and other structures.

A blizzard warning is a serious call to action. By understanding the risks and taking appropriate precautions, you can protect yourself and your loved ones.
