Okay kiddo, so you know how sometimes when it's really windy outside, you can feel the wind blowing on you and it can be pretty cold, right?
Well, sometimes when the wind blows really hard and it's very snowy outside, something called a ground blizzard can happen.
This is when the wind blows so hard that it picks up all the snow from the ground and blows it around in the air, making it hard to see anything because there's so much snow flying around.
It can be really dangerous because you might not be able to see where you're going or even breathe well because of all the snow blowing in your face.
So, just like you wear warm clothes and a coat when it's cold outside, it's important to stay inside or wear some special clothes that will help protect you from a ground blizzard's effects if one happens in your area.
