Air Quality & Wildfire News — July 25, 2026

Saturday brought a hard piece of news out of Colorado, an escalating fire fight in southwestern France, and more crews from the Northeast heading west to help. Here's the day in plain English.

A fourth firefighter has died from the Colorado burnover

Nathan Matthews, 43, of Lincoln, Nebraska, died Friday from burns he suffered in a June 27 burnover near the Colorado–Utah border, the federal Interior Department said Saturday. A burnover is when a fire spreads and closes off every escape route. Matthews was part of a Helitack crew — firefighters dropped in by helicopter to hit new, fast-growing fires in remote country — deployed in Mesa County, west of Grand Junction.

Three firefighters died at the scene: Emily Barker, 38, Nick Hutcherson, and Sydney Watson, 26. They were honored at a memorial service earlier this month. As WDIV reports, the crew deployed tent-like emergency shelters to try to shield themselves. The western US is contending with dozens of large fires this summer after months of dry weather, a record lack of snow in some areas, hot spells and erratic winds.

More than 250,000 people displaced in France and Spain

France is bringing in an A400M cargo aircraft to dump flame retardants on a fire burning in the Gironde region, about 20 miles west of Bordeaux, joining 18 other water- and retardant-dropping planes and helicopters. Interior Minister Laurent Nunez called the fight "long and very difficult." With winds expected to shift toward the city, crews were digging trenches and laying retardant to block it, and authorities ordered evacuations from parts of Bordeaux's western suburbs and nearby towns.

The Gironde fire and another in the Landes region have together forced 197,000 people to evacuate, Nunez said. Add roughly 70,000 evacuated in central Spain and the week's total across southern Europe passes a quarter-million. Prime Minister Sébastien Lecornu said the Gironde blaze had grown strong enough to generate its own winds. The government is rushing 1.5 million face masks into the region for people exposed to the smoke, NBC News reports.

A Massachusetts crew heads to Minnesota

A 10-person wildland crew from Massachusetts — a "Suppression Module" drawn from the Department of Conservation and Recreation and the Division of Fisheries and Wildlife — deployed Saturday to northern Minnesota to help contain the fires there. Connecticut's environmental agency sent a six-person crew to Quebec last Friday.

Smoke from the Minnesota and Canadian fires has covered Boston, Minneapolis, Chicago, Detroit, Cleveland, Pittsburgh, Philadelphia and New York City, prompting air quality alerts for more than 100 million people, NBC10 Boston reports. If you're under one of those alerts, it's a reasonable day to keep windows closed and run a filter indoors.

Michigan readers push back on blaming Canada

Three of Michigan's Republican members of Congress sent a letter to Canada last week faulting it for smoke drifting into the state. The Detroit Free Press published readers' responses, and they weren't sympathetic — including one from David Miller, mayor of Toronto from 2003 to 2010, who noted Canada sent water bombers and crews to help during California's 2024 and 2025 fires while Ontario now has over 150 fires of its own burning.

These are opinion letters, not reporting, but they capture something real about this smoke season: the haze crosses a border that the firefighting response has been crossing in both directions all summer.

Why this summer has felt so extreme in northern Illinois

Northern Illinois hasn't had its hottest summer on record — that was 2020, at a 76.7-degree average from June through August — but 2026 has stacked up tornadoes, humidity, repeated severe storms and wildfire smoke alerts. Illinois leads the nation with 178 tornadoes this year.

National Weather Service meteorologist Zachary Yack told Shaw Local the region has seen one really big heat wave so far, when the heat index topped 100 on June 29, June 30 and July 1, with temperatures headed back to the 90s by Sunday. State Climatologist Trent Ford added that rising humidity has pushed nighttime temperatures up faster than daytime highs — part of why hot days no longer cool off the way they used to.
