Microbursts are very seldom talked about, despite the fact that they pack all the punch of a tornado and have been known to push passenger jets right out of the sky, causing several fatal crashes over the years. A microburst is a sudden and very powerful downdraft of wind, and they are highly localised. They are commonly found in thunderstorms and involve a powerful downdraft of wind being pushed against the ground and then bursting out in all directions, creating sudden and powerful gales that can reach speeds of 150mph.

As seen in the video, the storm goes from what looks like an average storm to what could easily be mistaken for a large tornado, all in a matter of seconds. Perhaps the most unnerving part is at 0:28, where the microburst can clearly be seen advancing towards the cameraman, before easily ripping a large tree in half.
