The National Weather Service held 50 active Red Flag Warnings Wednesday, the same total as Tuesday, but the footprint shifted: Kansas and Tennessee joined the list of critical fire-weather zones while Texas and Utah dropped off. Ten states now carry warnings — Colorado, Idaho, Kansas, Montana, Nevada, Oregon, South Dakota, Tennessee, Washington and Wyoming.
Montana remains the epicenter, with warnings covering the Fort Peck Reservation, Daniels, Roosevelt and Sheridan counties, Dawson, McCone, Prairie, Richland and Wibaux counties, the Little Rockies and the Lower Missouri River Breaks, including the Charles M. Russell National Wildlife Refuge. The National Weather Service reported northwest winds of 15 to 25 mph with gusts to 35 mph across those zones, with humidity dropping as low as 10 percent south of the Missouri River and 20 percent near the Canadian border. No thunderstorm activity is expected to interrupt the dry, windy pattern.
Colorado carries some of the day’s most extensive warnings, stretching from the Colorado River Headwaters and Gunnison Basin — where west winds of 10 to 20 mph and gusts to 30 mph are forecast alongside relative humidity as low as 8 to 13 percent between 1 p.m. and 8 p.m. MDT — to the high country above 9,000 feet in Jackson, Grand, Summit, Boulder, Clear Creek, Larimer and Park counties. Further south, the Upper Arkansas River Valley around Lake and Chaffee counties and the Eastern San Juan and La Garita mountains, including Wolf Creek Pass and Creede, face a midday-to-evening window of west winds up to 35 mph and humidity as low as 8 percent, conditions the Weather Service says will let any new fire “catch and spread quickly.”
In Oregon, warnings span the Western Klamath and Umpqua national forests, the Umpqua Basin, the Western Rogue Basin and Illinois Valley, the Siskiyou Mountains, the Eastern Rogue Valley and the Southern Oregon Cascades — a swath of forested terrain now added to Tuesday’s Columbia Gorge concerns.
The Weather Service’s warning criteria remain unchanged: a combination of strong winds, low humidity and warm temperatures that lets fires ignite easily and spread rapidly once started. Outdoor burning is discouraged across every active zone, and the agency is asking residents to avoid any activity that could produce a spark. With the alert count holding steady at 50 for a second straight day even as individual states cycle on and off the list, fire managers across the Rockies and Pacific Northwest are watching for the pattern to either break with incoming moisture or expand further as the week continues.
