  • 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.

  • 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.
