MANKATO, Minn. (KEYC) - Check out this amazing footage captured by Greg DeVore from earlier this afternoon near Terril, IA. This video shows a landspout, which is part of the tornado family but it forms differently.

Landspouts form as strong updrafts move over an area of strong surface vorticity (rotation). The updraft, if strong enough, will stretch the surface rotation upwards, resulting in a landspout. This phenomenon is fairly brief and lasts from anywhere between a few seconds to a few minutes.

Landspouts also tend to be fairly weak. Even though they tend to be brief and not as strong as tornadoes they shouldn’t be taken lightly. Landspouts should be treated as tornadoes and you should seek shelter immediately.
