Wildfire Daily - August 15, 2026

The Overnight. The United States stayed pinned at its highest national readiness posture through the last twenty-four hours, with 93 uncontained large fires burning across the West and roughly 29,600 personnel assigned. Washington's Little Giant Fire remained the top national priority, cooler air and Thursday rain eased pressure in the Nevada-California borderlands, and Oregon opened two new fires even as its biggest incidents crept forward under a weekend storm threat.

Abroad, southern Europe stayed in crisis. Spain's Niebla fire in Huelva pushed past 38,000 hectares, the largest wildfire in Andalusian history, while a wall of flame on Greece's Halkidiki peninsula forced about 500 tourists to flee by sea. A deadly blaze near Omis, Croatia injured 40 people and killed at least one. Here is the last day in wildfire.

Roughly 80 percent United States, 20 percent global. Biggest and most active first.

Chelan County, Washington. 128,085 acres, 7 percent contained. 1,824 structures threatened, 0 destroyed, 1 injury. 2,266 personnel assigned.

The Cascades blaze northwest of Leavenworth is the largest and least-contained major incident in the country and the number one draw on national resources. Acreage read flat day over day, but that reflects a missed infrared mapping flight rather than a halt in spread, so NIFC carried a nominal 597-acre placeholder. Level 1, 2 and 3 evacuations remain in force with a Red Cross shelter open at Entiat.

Why it matters. The single most resource-hungry fire in the nation keeps Cascades communities under active "Go Now" orders.

Washoe, Sierra and Lassen counties, Nevada-California. Roughly 88,400 to 91,100 acres, 31 percent containment. NIFC logged a plus 17,665-acre change, the day's largest.

Most of that jump is a merger artifact: the Bug Fire absorbed the adjacent Fred Mountain Fire, so the perimeter grew on the map more than on the ground. Cooler weather and Thursday rain actually helped crews, and evacuations are rolling back, with a Lassen County order downgraded to a warning and US-395 reopened. The nearby Stallion Fire sits at 44 percent contained.

Why it matters. A big number that reads as growth is largely a complex merger; the real trend is toward containment and residents heading home north of Reno.

Hood River, Wasco and Clackamas counties, Oregon. About 86,974 acres, 20 percent contained, up roughly 1,495 acres. Level 1 to 3 evacuations across three counties.

Growth ran the east flank near Tygh Creek and Shadybrook, where National Guard structural task forces are prepping homes. A shelter is open at The Dalles Middle School as weekend thunderstorms, gusty winds and falling humidity threaten containment lines.

Why it matters. An unstable weekend forecast could undo hard-won line right where the fire nears populated ground.

Oregon-Idaho border. Roughly 582,000 acres, 54 percent contained, up about 1,964 acres, with a perimeter near 670 miles.

Majority-contained but still expanding modestly, Big Grass remains the biggest active fire nationally by area and continues to soak up crews and aircraft along a sprawling high-desert edge.

Why it matters. Even at better than half contained, a fire this size keeps a heavy resource draw during peak season.

Also burning.

In British Columbia, 112 wildfires were active and the Bald Range fire near Summerland held at 19,149 hectares and out of control, with more than 6,000 properties still under evacuation order across the Okanagan even as other BC evacuees were cleared to go home. In Spain, the Niebla fire in Huelva passed 38,000 hectares to become the largest wildfire in Andalusian history, while Aragon's Penas de Riglos fire topped 12,000 hectares. On Greece's Halkidiki peninsula, a three-kilometer front drove about 500 tourists to evacuate by sea, with two firefighters hospitalized. France passed 115,000 hectares for the season, a national record, and a heat-driven fire near Stourbridge in the English West Midlands damaged several properties. EFFIS put the EU total near 568,000 hectares from more than 1,600 fires through August 13.

Why it matters. The Mediterranean stayed in emergency all through the window, with record-setting fire in Spain and a dramatic sea rescue in Greece on the same day.

A quiet day for new United States responder incidents; the sharpest safety news came from abroad and from the season's data.

Split-Dalmatia County, Croatia. Roughly 900 hectares burned; 40 people treated, 14 hospitalized, 7 in life-threatening condition; about 1,200 evacuated.

A fire spreading toward Omis burned homes, vehicles and boats across several coastal hamlets by midday August 14, flared again in the afternoon and prompted a heavy air response. One body was found in the burn area and a Bosnian national was reported missing, in what local officials called one of the worst wildfires in Croatian history.

Why it matters. It is the single largest civilian-casualty wildfire event of the window and the dominant global safety story right now.

Leicestershire, United Kingdom. Three simultaneous wildfires; four firefighters with heat-related injuries, one hospitalized then discharged.

Crews fought fires near Ibstock, Ratby and Swinford on the UK's hottest day of the year so far, with the largest drawing eight engines. None of the injuries were life-threatening, but the cluster is a concrete marker of responder heat risk during the European heatwave.

Why it matters. The same heat load is bearing down on Western US crews working long shifts on the line.

United States, season to date. 12 entrapments year to date, the most since 2006 and above the 20-year average of about nine.

A new Associated Press analysis found six of the season's 13 wildland firefighting deaths came from entrapments, well above the historical share, with dozens of injuries besides. Firefighters interviewed tied the elevated risk to a full-suppression posture and 2025 Forest Service staffing cuts of roughly 6,000 jobs.

Why it matters. It puts hard numbers on a season that is now statistically the deadliest by entrapment in twenty years.

A thin 24 hours for deals: no new funding round, acquisition or contract award crossed the wire. The live money story is California's utility-liability fight.

Sacramento, California. Governor Gavin Newsom is pressing an end-of-session legislative package to shore up California's investor-owned utilities against wildfire-liability costs and reinforce the state wildfire fund, with Los Angeles and Eaton fire survivor groups fighting a utility-backed coalition over the terms. The package directly shapes the equity and credit outlook for PG&E and Edison International and the solvency of the fund.

Why it matters. It is the biggest utility-finance wildcard in the sector, and the session clock makes a move plausible any day.

Los Angeles, California. A judge balked, at least for now, at holding Southern California Edison automatically liable for the LA-area Eaton Fire without trial, a procedural win that eases near-term liability certainty for parent Edison International. The ruling feeds the same investor-risk narrative as the Sacramento package.

Why it matters. Liability outcomes here ripple straight into insurer exposure and utility cost-of-capital across the West.

Light on launches; the in-window action was federal fire aid and a notable study on how fast fires burn.

Rogue River, Oregon. FEMA approved a Fire Management Assistance Grant for the roughly 550-acre Fielder Mountain Fire, reimbursing up to 75 percent of eligible firefighting costs, as Oregon deployed an incident management team and the cause stayed under investigation. The approval lands amid a season-long tug-of-war between the state's congressional delegation and the administration over Oregon fire-aid decisions.

Why it matters. Federal cost-share decisions are a recurring policy flashpoint that shapes how fast small fires get resourced.

Science Advances. A study led by Jonathan Coop, drawing on about 3,500 fires and more than 33,000 daily growth events, found that fast-spreading fires produce disproportionately higher burn severity and leave scorched ground farther from surviving seed trees, pushing some western and boreal forests toward lasting non-forest states. The authors argue rate of spread deserves weight alongside acreage in fuels and suppression strategy.

Why it matters. It bolsters the case for rapid initial attack and better detection, the very tools this brief tracks.

A quiet stretch for personnel news, led by a mid-season consolidation of authority inside the Forest Service.

U.S. Forest Service, effective August 13. The agency placed all national fire and aviation authorities under Sarah Fisher, Deputy Chief for Fire and Aviation Management, Safety and Employee Wellbeing, with Geographic Area Fire Directors now reporting directly to her and key expenditure and emergency-declaration approvals routed through her office. The move centralizes decision-making at the height of fire season, alongside the parallel stand-up of a DOI-led U.S. Wildland Fire Service.

Why it matters. Putting national response, preparedness and aviation on a single line of authority mid-season is a meaningful structural change during an active reshuffle.

Ventura County, California. The Ventura County Fire Department named Kylie Tillema to lead its Fire Prevention Bureau as fire marshal, arriving from Riverside County Fire with more than a decade in prevention, code enforcement and community risk reduction. The appointment fills a key prevention post in a county repeatedly hit by wind-driven wildfires.

Why it matters. WUI code enforcement leadership is front-line risk reduction in one of California's most fire-exposed counties.
