National Overview
National Overview
The U.S. remains at Preparedness Level 5, with 98 uncontained large fires burning across the country and 29,840 personnel assigned nationally, including 628 crews, 1,804 engines, and 183 helicopters.
NIFC reports 3,736,624 acres burned on large fires, a figure that continues to grow as new incidents develop and mapping in the Northwest catches up to fire growth.
The Northwest remains the dominant story nationally, with 46 uncontained large fires in the region.
Humidity is slowly moderating across the Inland Northwest and northern Rockies, with near to slightly above normal temperatures and improved overnight recovery resulting in shorter burn periods in those areas.
Conversely, inland California, the northern Great Basin, and much of Wyoming will see persistent very low relative humidity of 5 to 15 percent, poor overnight recovery, and temperatures 5 to 15°F above normal.
Isolated to scattered mixed wet and dry thunderstorms are expected from the eastern Sierra across the central and southern Great Basin into Utah, Colorado, and the Southwest, with the driest and most ignition-prone storms targeting central Nevada, northern Utah, and northwest Colorado.
No significant rain is forecast for the next seven to ten days across the Northwest.
Washington
Washington carries more than 20 active large incidents, with several continuing to draw the bulk of resources in Okanogan, Chelan, and Ferry counties and in the Spokane area.
The Little Giant fire in the Okanogan-Wenatchee National Forest has grown to 111,429 acres and remains only 2% contained; a transfer of command from CIMT (CA Team 2) to CIMT (NW Team 12) is occurring today, with extreme fire behavior continuing including crowning, uphill runs, and long-range spotting, and numerous structures and critical infrastructure threatened.
The Sinlahekin fire, one mile west of Tonasket, has now reached 141,411 acres at 42% containment, with active torching, short-range spotting, and smoldering, and residences and critical infrastructure threatened.
The Kaiser Canyon fire stands at 138,235 acres and 63% containment, with a reduction in acreage attributed to more accurate mapping.
The Ptarmigan fire in the Okanogan-Wenatchee National Forest, managed by NIMO Team 3, has grown to 22,682 acres at 8% containment, with active uphill runs, group torching, and spotting.
The Three Queens fire near Snoqualmie Pass has grown to 2,000 acres and remains uncontained, with active wind-driven runs and short-range spotting and evacuations in effect.
New this report, the Modrite fire in the Northeast Region has reached 57,133 acres at 60% containment, with active flanking, group torching, and uphill runs and numerous residences threatened.
Multiple additional incidents in the Spokane vicinity — Old Trails, Autumn Lane, and Fairview — remain active with moderate behavior near populated areas, and evacuations are in effect around all three.
Humidity is slowly moderating across eastern Washington, with improved overnight recovery and shorter burn periods expected compared to last week's worst days, though smoke and haze remain widespread.

Arizona
Arizona's large-fire footprint on the IMSR is limited to the Foster fire in the Colorado River District, a new incident at 311 acres and zero containment near Winterhaven with active torching and short-range spotting.
Monsoon activity is the primary variable today.
Wetter storms are expected to be scattered near and south of the Mogollon Rim, providing meaningful relative humidity recovery in those areas, while isolated mixed wet and dry storms in northern Arizona and the southern Great Basin carry some ignition potential in drier fuels.
Thunderstorm outflow winds can still produce sudden and erratic behavior on existing incidents, and new lightning ignitions away from storm cores cannot be ruled out.
- Flagstaff — mid-70s, likely storms, breezy
- Prescott — upper-80s, hot, isolated storms
- Tucson — around 100, hot, isolated storms
New Mexico
New Mexico shows active incidents across multiple counties.

The Johnson fire in the Gila National Forest has grown to 426 acres and zero containment, with moderate creeping, smoldering, and backing and structures threatened.
The Frio fire near Albuquerque is at 152 acres and 75% contained.
Lightning remains an active ignition concern today, particularly where storms produce little rainfall, and thunderstorm outflows can generate sudden wind shifts near existing incidents.
- Santa Fe — upper-80s, warm, isolated storm risk
- Albuquerque — low-90s, hot, breezy
- Gallup — mid-80s, dry, isolated storms
