Wyoming Weather Alert: Riverton Faces Strong Winds and Thunderstorm Risk Through Friday Night, September 12

Central Wyoming is facing rough weather this weekend, especially around Riverton. Strong winds and thunderstorms are expected to roll through, bringing not just rain but also fire danger and travel trouble. With gusts possibly hitting 50 mph, drivers and residents are being advised to stay alert and take safety steps in advance.

High Winds and Fire Danger on Friday

On Friday, central Wyoming — especially Fremont County — will see strong winds, dry conditions, and scattered thunderstorms. The National Weather Service in Riverton has warned that wind gusts could reach up to 50 mph in some places.

This kind of weather is especially dangerous because of dry lightning, which can start new wildfires. Combined with already dry vegetation, the risk of fire is quite high.

Key Concerns on Roads Like U.S. 26 and I-25

If you’re planning to travel along U.S. Highway 26 near Riverton or heading east on I-25, be prepared for:

Sudden wind gusts

Blowing dust reducing visibility

Loose objects on the road

Fire crews possibly responding to new wildfires

Authorities suggest securing outdoor items and completely avoiding open burning for now.

Saturday Brings More Storms, Especially Up North

While Saturday may see slightly cooler weather, scattered showers and thunderstorms are expected again — mainly over western and northern Wyoming. However, even with the rain, strong winds are still a concern.

Make sure you’re dressed for quick weather changes if you’re heading outdoors. The risk of lightning and gusty winds continues through Saturday.

Improving Weather by Sunday

The good news is that things will begin to calm down by Sunday. Expect mostly sunny skies and a high of around 77°F. Winds will also be much lighter, giving residents and travelers a break from the harsh weather.

Next Week Outlook: Cooler Temperatures, More Storms

Starting Monday, Riverton will experience cooler weather with highs in the low to upper 70s. However, storm chances return between Monday and Wednesday. Winds will remain breezy, with gusts picking up again on Tuesday.

Stay Weather-Aware

People in central Wyoming are being advised to:

Stay updated with local weather forecasts

Check road conditions before driving

Avoid outdoor burning completely

Be ready for sudden weather changes
