It is called a wet microburst, but when you see it in a time-lapse video like this, it can be anything but “micro”.
The footage captured by Tucson photographer Brian Snider shows a microburst absolutely unloading on an area near the city.
"Notice how the ball of rain falls from the sky and starts separating before hitting the ground," wrote Snider.
A microburst is a sudden downward burst of wind from the base of a thunderstorm. The air can rush towards the ground at speeds of 60 MPH before impacting the surface and spreading out in all directions.
