When	Event	Place named	Harm	What the report says
August 2000	Wildfire	Thermopolis	1 killed, 1 hurt	no account filed
May 2015	Flash Flood	Thermopolis	$1,500,000	Very heavy rain fell in southern Hot Springs County. This triggered numerous mud and rock slides, some tumbling several hundred feet or more to the bottom of the Wind River Canyon. State Highway 789 through the canyon was covered with mud, rock, and debris in several locations between mileposts 120 and 123. One Wyoming Department of Transportation employee was briefly trapped in his front-end loader as he tried to clear away small slides at the onset of the event. The massive amount of debris on the highway resulted in the closure of the road from Sunday afternoon, May 24, until Wednesday morning, May 27. Additional slides on the west side of the Wind River Canyon destroyed several sections of railroad track that resulted in a halt of train traffic for several days.
September 2024	Tornado (EF0)	Thermopolis	$50,000	A brief landspout tornado touched down in downtown Thermopolis, near the intersection of US Hwy 20 and WY Hwy 120. Maximum winds were estimated between 65 to 75 mph as it caused damage to sheet metal roofing and car windows.
