An Introduction to Blizzard Alerts

Blizzards are severe winter storms characterized by heavy snowfall and strong winds, leading to dangerously low visibility and life-threatening conditions. In the United States, the National Weather Service (NWS) issues Blizzard Warnings to alert the public about these hazardous conditions.

What is a Blizzard Warning?

A Blizzard Warning is a hazardous weather statement issued by the NWS indicating that blizzard conditions are imminent or occurring. To warrant this warning, the following criteria must be met:

  • Heavy Snowfall: Accumulations of snow that significantly reduce visibility.

  • Strong Winds: Sustained winds or frequent gusts of 35 mph (56 km/h) or greater.

  • Reduced Visibility: Visibility of 1/4 mile (400 meters) or less due to falling and blowing snow.

These conditions must persist for at least three hours to qualify as a blizzard. (en.wikipedia.org)

Understanding Blizzard Warnings

Blizzard Warnings are issued by NWS Weather Forecast Offices (WFOs) and are typically broadcasted through various channels, including NOAA Weather Radio, local media, and the Wireless Emergency Alerts system. It's important to note that while these warnings are designed to inform the public, they are not always sent as alerts to mobile phones. (en.wikipedia.org)

Safety Measures During a Blizzard

When a Blizzard Warning is in effect, it's crucial to take immediate precautions to ensure safety:

  • Limit Travel: Avoid traveling unless absolutely necessary. If you must travel, inform someone of your destination and expected arrival time.

  • Stay Informed: Monitor weather updates from reliable sources, such as the NWS website. (weather.gov)

  • Prepare an Emergency Kit: Equip your vehicle with essentials like blankets, non-perishable food, water, a flashlight, and a first-aid kit.

  • Seek Shelter: If caught outside, find shelter immediately. Avoid sheltering under trees or near structures that could collapse under the weight of snow and ice.
