Idaho Fires

Daily Wildfire Report for Idaho - August 26, 2026

Overview

Idaho is experiencing a severe 2026 wildfire season, prompting a state disaster emergency declaration due to extreme drought conditions, dry lightning strikes, and human-caused ignitions. Statewide fire activity is running well above the 10-year national average, with hundreds of thousands of acres burned. The current National Preparedness Level remains high, indicating that national and state firefighting resources are heavily committed and stretched thin across the region.

Current Situation

Fire Activity: There are currently multiple active fires in Idaho, with significant wildland fire activity occurring across the state's rugged backcountry and southern rangelands. Recent lightning storms have sparked several new starts over the last 72 hours, requiring immediate response from federal, state, and local agencies. Firefighters are working to contain these fires while navigating critical fire weather and exceptionally dry fuels.

Key Fires:

• Big Grass Fire: Burning along the Oregon-Idaho border in Owyhee County, this massive fire has reached approximately 579,000 acres and is 85% contained. It is burning rapidly through rangeland fuels, dry vegetation, and continuous short grasses. Level 3 “Go Now” evacuation orders remain in effect for areas including Pleasant Valley, Flint Creek Road, and the 45 Ranch. Crews are focused on protecting communities, transportation routes, and critical infrastructure.
• Tartar Fire: Located in Washington County near Weiser, this large-footprint fire has burned 158,027 acres and is currently 98% contained. Firefighters are maintaining containment lines and monitoring the perimeter for hotspots.
• Flint Fire: Ignited on August 24 in Owyhee County, this new fire has quickly grown to nearly 6,500 acres with 0% containment. Fueled by dry rangeland grasses and driven by gusty winds, the rapid spread has prompted active firefighting efforts to protect nearby areas and limit expansion.
• Moose Mountain Fire: Burning in Clearwater County, this fire is currently at 4,591 acres and 8% contained. It continues to burn through heavy timber and rugged terrain, making direct containment efforts challenging for ground crews.

Prescribed Burns and Land Management: To reduce the risk of new human-caused fires, Stage 1 Fire Restrictions are in effect across multiple areas, including BLM Idaho Falls District lands and central Idaho. These restrictions strictly prohibit campfires outside of designated, agency-installed metal or concrete fire pits and limit smoking to enclosed vehicles or cleared areas. Residents should check local county ordinances, as burn bans remain actively enforced in high-risk zones.
Air Quality: Wildfire smoke is impacting air quality, particularly near the Big Grass Fire and across southern Idaho. Residents are advised to monitor real-time air quality alerts, keep windows closed, and utilize high-performance air purifiers or set HVAC systems to recirculate mode if smoke levels rise.

Weather and Wind Warnings

Current Weather: Hot, dry conditions persist across much of the state, with critically low relative humidity contributing to highly combustible vegetation.
Forecasted Weather: A Red Flag Warning is in effect for Southwestern Idaho, including the Owyhee Mountains and Southern Highlands. Scattered thunderstorms are expected to produce abundant lightning and strong, erratic outflow winds with gusts up to 50-55 mph. These critical fire weather conditions mean that any new ignitions will catch easily and spread rapidly, potentially causing existing fires to change direction and exhibit dangerous fire behavior.

Recommendations

Public Awareness: Residents are advised to avoid any activities that could produce sparks, such as using lawnmowers on dry grass or leaving outdoor fires unattended. Ensure trailer chains are secured and never park vehicles on dry vegetation. It is crucial to have an emergency plan and go-bag ready, and to heed all local evacuation orders immediately.
Resource Allocation: The state disaster emergency declaration has freed up state resources and mutual aid support for the hardest-hit counties. Firefighting personnel and resources are being strategically prepositioned for initial attack on new lightning starts to prevent them from growing into major incidents.
