EFU Tornado — Goshen, Wyoming

2024-06-20 · near Fonda, Goshen, Wyoming

Event narrative

A brief tornado was observed in rural Goshen County by numerous storm spotters

and emergency management personnel. Due to the rural nature of this tornado, only

limited damage to fencing was found, as well as scattered plant debris. Review of

video and photo sequences along with radar time-matching indicate that this tornado

likely began as a landspout, but quickly gained mesocyclonic characteristics as it

interacted with the updraft base, condensed a funnel, and slowed/occluded into the

storm. Regardless, without any damage of note this tornado will be recorded as EF-U.
