SLIDESHOW: Landspout tornado over Mission Valley

ST. IGNATIUS, Mont. — Tuesday afternoon, a potential landspout tornado touched down in the Mission Valley, visible from towns including Charlo and St. Ignatius.

Landspout tornadoes are often weaker, smaller and much shorter lived than supercellular tornadoes on the Great Plains. Because of this, landspouts are rarely detected by Doppler weather radar. Regardless, they are still capable of producing damage.

The development of landspouts is more closely related to waterspouts.
