Riverton, Wyo. – Drivers across central and western Wyoming should prepare for unsettled skies as storms push into the region Monday afternoon. Thunderstorms may intensify along I-25 near Casper and U.S. 26 through Riverton, raising risks of slick roads and sudden downpours.
According to the National Weather Service in Riverton, isolated thunderstorms will develop Sunday evening with a stronger round expected Monday. Storm activity could continue daily through Thursday as monsoonal moisture flows north from the desert Southwest. Tuesday and Wednesday remain the most active periods with the highest chances for heavy rain.
Communities in Fremont, Natrona, and Sweetwater counties may see lightning, gusty winds, and brief flooding in low-lying areas. Outdoor events and travel could be disrupted, particularly during the evening commute hours. Motorists are urged to slow down on wet pavement and avoid low-water crossings.
Energy crews and emergency responders warn that isolated power outages remain possible where lightning strikes or gusty winds take down lines. Residents should charge devices ahead of time and keep flashlights handy in case of interruptions.
The unstable pattern will ease by Friday, but not before several rounds of thunderstorms roll through Wyoming’s mountains and valleys. Spotters are encouraged to report hail or flooding impacts to local authorities.
