Well kiddo, a bow echo is like a big, scary storm that can cause a lot of damage. If you look at a map of where the storm is happening, it might look like a bow or half-circle shape. That's why it's called a "bow" echo!
The storm can have really strong winds that blow things around and knock over trees and power lines. Sometimes it can even cause flooding with lots of rain.
It's important to stay safe during a bow echo by staying inside and away from any windows or doors. It's also a good idea to have an emergency kit ready just in case the power goes out or you need to leave your home quickly.
Remember, even though bow echos can be scary, they don't last forever and there are people who work really hard to keep us safe during storms like this.
