long-track tornado

A long-track tornado is a rare type of tornado with a continuous damage path significantly longer than average. While most tornadoes are associated with supercells and last only a few minutes, some storms produce a tornado cyclone that can spawn a series of tornadoes, known as a tornado family. In very infrequent cases, this tornado cyclone remains stable for hours, resulting in a single, long-lasting tornado. Distinguishing between a long-track tornado and a tornado family can be challenging, as some events, like the Great Tri-State Tornado of 1925, have documented paths over 300 km, but it's uncertain if it was a single tornado or a family.1
