Montana Tornadoes 1950-2012
This page lists the date and location of all the tornadoes that have occurred in Montana from the year 1950. If you are interested in reading about the “worst” tornadoes that have struck Montana(and all other states), see this page on our site. If you want to find out about specific tornadoes that have occurred since 2012, check out the NCDC Storm Events page.
Move your mouse over the map to see the county name and FIPS number (Federal Information Processing Standard). Click on the county or use the drop-down menu to navigate to your county of interest.
From there you can find data on each county that has had tornadoes since 1950. You will find the tornado ID number, the date, the event number, the time it occurred, the number of deaths and/or injuries caused, the F-Scale or EF-Scale, and the map coordinates. You can even copy the beginning and ending set of map coordinates into Google maps to see the path that the tornado took. If your county is not listed, it has not had a tornado officially listed during this period.
