• Red Flag Warnings in effect across five states as critical fire-weather conditions develop

    The National Weather Service (NWS) has Red Flag Warnings in effect across parts of Montana, Wyoming, North Dakota, Idaho and South Dakota on September 10, 2026, as very low relative humidity, dry vegetation and gusty winds produce critical fire-weather conditions across the northern Rockies and northern Plains. Minimum relative humidity may fall as low as 5% in southeastern Wyoming, while wind gusts may reach approximately 65 km/h (40 mph) in parts of Wyoming and Montana.

  • Extreme Heat Watches issued for Utah, Montana, and northern Wyoming, temperatures up to 43°C (110°F) forecast through July 27

    Extreme Heat Watches have been issued for large portions of Utah, Montana, and north-central Wyoming as widespread dangerous heat is forecast from Friday, July 24, through Sunday, July 26, with some areas remaining under hazardous conditions into early next week.

  • Record-breaking heat to peak through July 14 from the Great Basin to the Northern Plains, U.S.

    Dangerous and potentially record-breaking heat is forecast to peak through July 14, 2026, across the western and north-central United States. Billings, Montana, already shattered its all-time temperature record on July 12, while Salt Lake City, Utah, tied for its second-highest reading ever, just short of its own all-time mark. More locations could still challenge records as the heat continues into Tuesday. Very warm nights are adding to the danger by increasing heat stress over several consecutive days.
