EDEN — SweetwaterNOW reader Becky Cordova submitted these photos taken by her husband David Cordova. David was on the way home from his job as a Crane Operator when he stopped near Eden and took these photos.
Brett McDonald Science and Operations Officer at the National Weather Service Office in Riverton said that, “Based on our interpretation of the pictures, and combining that with radar data at the approximate time, we believe that the pictures are indeed of a tornado. This tornado is typically called a landspout tornado, one in which the circulation is first generated near the ground and then rises up to connect with weak circulation in the lowest levels of the thunderstorm. They are very short-lived, and in Wyoming do exactly what the pictures show – swirling dust at the surface with not much of a condensation funnel showing a connection to the cloud. I would classify this tornado as an EF0 on the Enhanced Fujita scale.”
McDonald said that the officer recorded two tornadoes just like this on Tuesday May 6, 2014 (the day before) about 15-20 miles north of Riverton.

David Cordova captured theses photos of a tornado near Eden Wyo on May 7.A screen shot of the composite reflectivity measured from the Riverton radar over the Eden area at 2:55pm. It certainly shows a thunderstorm!National Weather Service data agrees that the cloud captured here is a tornado.Storm-relative motion data around the time the photo was taken. This is the velocity data combined with the effects of the storm motion. The reds are motions away from the radar, and greens are toward the radar. The image shows a counterclockwise circulation within the storm at about 6500 ft above ground level – so there was some circulation within the storm, but not terribly strong. With the limitations of the radar around the mountains, we just can’t “see” anything closer to ground level. Click the photo for a larger version.
