The National Weather Service (NWS) in Bismarck, North Dakota, announced the expiration of a Red Flag Warning for Slope and Bowman counties on October 23, 2026. The warning officially ended at 9:00 PM CDT, with the NWS citing cooler temperatures and increasing humidity as reasons for its termination. A strong cold front was also expected to move through the area that evening, bringing with it strong northwest winds.

This Red Flag Warning had been in effect from noon to 8 PM MDT (1 PM to 9 PM CDT) on October 23. It covered Slope and Bowman counties, located in far southwest North Dakota. The warning was issued due to a combination of strong winds and low relative humidity, which created critical fire weather conditions.

Forecasts for the affected area indicated very warm and breezy conditions throughout the afternoon and early evening. Relative humidity values were projected to drop significantly, ranging from 15 to 25 percent. Winds were expected to be from the south, around 20 mph, with gusts reaching up to 40 mph. These specific atmospheric conditions meant that any fires that developed would spread rapidly.

During the warning period, the NWS advised against outdoor burning. The public was also urged to avoid outdoor activities that involved open flames or sparks. Adherence to local burn restrictions was strongly recommended to prevent potential wildfires. The termination of the Red Flag Warning signaled a decrease in immediate wildfire risk for these North Dakota counties, following a period of elevated danger.
