Air Quality & Wildfire News — August 17, 2026

Rain arrived overnight across parts of Europe's fire zone, and it helped — but not everywhere, and not enough. Here is where things stood Monday, plus a US wildfire app moving into new territory.

Rain slows Belgium's High Fens fire, but it is not out

A cold front brought overnight rain to eastern Belgium, and the wildfire in the High Fens nature reserve made only "limited" advance as a result, Breitbart News reports from a Monday morning update by the local governor's office. Crisis management spokesman Tony Hosmans said the blaze was no longer advancing toward the German border and was contained "wherever intervention is possible," while cautioning it had not yet been brought under control. Around 500 firefighters and emergency crews have mobilized. The fire broke out Friday, for reasons still unknown, in an expanse of boggy peatland, pine forest and hiking trails.

The fire has burned an estimated 30 square kilometers (about 12 square miles) in Liège province, and Belgium's King Philippe interrupted his summer vacation to visit emergency services there, the Associated Press reports. Nicolas Yernaux, spokesperson for the Wallonia regional public services, said crews held the fire where firefighters could reach it, but one area remains totally inaccessible with the fire still burning toward Monschau, Germany. Rain helped contain the edges and reduce flare-ups from smoldering ground, he said, but did not significantly affect the center of the fire. Precautionary evacuation orders remained in effect Monday for hundreds of residents, and aircraft from Norway, Sweden, Germany and the Netherlands are assisting.

Peat fires are stubborn in exactly this way: rain can wet the surface while the ground underneath keeps burning. If you live downwind of one, expect smoke to come and go for longer than the headlines suggest.

Two killed in a wildfire on the Greek island of Salamina

Two people were killed Sunday in a wildfire on Salamina, the island west of Athens, Greek firefighters said. The bodies were recovered in the village of Peristeria, where strong winds drove a rapidly spreading blaze, Arkansas Online reports. A second blaze was reported in the Selini area, and firefighting and coast guard vessels evacuated some 500 beachgoers. About 260 firefighters responded, with 15 ground teams, 10 aircraft and eight helicopters.

The island had been placed at high wildfire risk that day, with near gale-force winds. "These conditions enabled the fire to quickly reach dangerous proportions and spread rapidly within seven minutes toward nearby residential areas," said Fire Brigadier General Vasileios Vathrakogiannis. Greek fire department investigators were examining the cause on Monday. Separately, a fire that flared up near Athens' main airport was quickly extinguished.

France's Landes fire is under control

In southwestern France, a fire in the Landes region is under control and some residents have been allowed to return home, the Associated Press reports. France, Greece, Portugal and Spain were all battling major fires over the weekend. Europe is going through one of its hottest and driest summers on record, which a recent study said was fueled by climate change.

Watch Duty adds nationwide flood coverage

Watch Duty, the nonprofit wildfire-tracking app that many Americans downloaded during the Los Angeles fires in early 2025, has expanded into flood monitoring. Nationwide flood coverage went live June 8, giving anyone in the US access to flood data and mapping alongside the wildfire information already in the app, Digital Trends reports.

CEO and cofounder John Mills told Fast Company the expansion is part of a plan that has been brewing for years. The flood system pulls together official warnings, precipitation data, river gauges and mapping that would otherwise sit across separate services, drawing on Doppler radar, USGS stream gauges, NOAA and National Weather Service reports. Trained reporters still add verified context during dangerous events. The organization expanded wildfire monitoring nationwide in December 2025, and its 2025 annual report says yearly active users reached 16.8 million.
