​Eastern Utah and Western Colorado Tornado Archive

Note #1: each section goes from mid previous decade (2015) to the current decade (2025), but arent exact. I am going to keep it for now how it is, and adjust them eventually.

​

Note #2: The Eastern Utah section contains the source "Utah Doesn't Get Tornadoes" by Blue Ayanami. The person has rated most of the tornadoes so I have included their ratings which arent official, but are second to the official one.

​

Note #3: I am including some tornadoes that didn't happen in Eastern Utah and Western Colorado, but near enough, like the 1961 Green River F2 and 1993 

Chepeta Creek/Ashley Forest F3. 

​

Note #4: Radar Imagery will have some photos of events that might have been captured on radar, but due to the nature of the NWS Grand Junction radar, plus other things, there will be limited/iffy imagery, and the velocity signatures will tend to be weak. 

​

Note #5: I will include satellite imagery in the same page as radar, and will credit people as needed. 
 

Note #6: The June 16th tornadoes (Elk Springs and Leona Spring) may not have happened on the same day as the Mount Lena tornado, but as noted by Blue Ayanami, June 16th "appears to be the only date in 2015 that tornadic storms passed through the area, so it's likely they all occurred on the same day"

​

Note #7: Newspapers from pre-1950 will tend to use the word "tornado" to maybe mean an actual tornado, but might mean a windstorm, dust devil, or other wind related phenomena. I'm including those articles as theres of course a chance that they mention actual tornadoes, but we will likely never know
