What the reports say
Written by National Weather Service staff at the time of the event · public domain
Wyoming State Highway Patrol reported tornado on the outskirts of Bill with corresponding video confirmation of a visible condensation funnel east of the hotel in town. A later report via social media presented photographic evidence of tornadic damage to a manufactured home east-southeast of Bill with a corner of the roof peeled off consistent with EF-0 damage.
The second tornado formed as the first tornado was lifting to the west, touching down near the West Fork of La Bonte Creek and Esterbrook Road. The tornado quickly strengthened to EF1 intensity as it moved along La Bonte Creek passing near a ranch house off Esterbrook Road. Most of the damage was to trees that were snapped mid trunk in a 150 yard path. The tornado lifted as it moved east of La Bonte Creek. The NWS survey team lost track of the tornado as it moved southeast into open country, so it is possible that track extended farther than the survey results indicated. The survey team also continued to investigate reports of damage at Esterbrook Campground to the southeast, to see if this damage was associated with the same tornado. Start and end times and locations and times of the tornado were estimated from eyewitness accounts and radar data.
