EF3 Tornado — Oregon, Missouri

2025-03-14 · near Koshkonong, Oregon, Missouri

Event narrative

A 24 mile long tornado path was determined by a combination of NWS survey, storm reports, and satellite damage to have moved from just north of Koshkonong to 2 miles north of Alton before lifting 8 miles northeast of Alton. Maximum width was approximately a half mile wide though it was likely considerably narrower in places. While much of the path was to trees along with several outbuildings, the tornado damaged a few homes including a south facing ground level home off County Road 402 where it caused EF3 damage. The track continued northeast of Alton into the Mark Twain National Forest with satellite detecting an intermittent path of uprooted trees to near the Eleven Point River at Turners Mill.
