Criteria For A Blizzard

12/30/2021 (Permalink)

We New Englanders know the term “blizzard” all too well. In fact, we hear it around this time of year pretty much every year. Besides heavy snow, what does a blizzard actually mean? What makes a blizzard a blizzard and not just your run of the mill snowstorm? Here at SERVPRO Danvers/Ipswich we can answer these questions for you!

What is a Blizzard?

In order for a snow event to be considered a blizzard it must meet three criteria: high winds, low visibility, and last a substantial duration of time. 

• The winds need to be at least 35 mph
• The visibility needs to be less than a ¼ mile in front of you
• These conditions need to last for at least three hours 

Oh yeah, and of course the heavy snow. Where the snow comes from also can vary in a blizzard. Snow that qualifies as a blizzard can either be caused by heavy falling snow, or it might be classified as a ground blizzard, which is blowing snow that has already fallen. 

Whether it is a ground blizzard or freshly fallen snow, if it meets the three criteria above, it’s an official blizzard. In storms like this, it is best to stay inside and leave the sledding and skiing for the next day when conditions are calmer. 

At SERVPRO, we have seen our fair share of storms and are ready to help you prepare for any incoming blizzards and resulting storm clean up! Contact us today for all your winter storm worries.
