Rare pyrocumulonimbus clouds form over wildfires in France

The record

Written from the 1 report below. Nothing here is unsourced.

Scientists and France's National Firefighters Federation report that a rare pyrocumulonimbus, or fire cloud, has formed over the large wildfire in southwest France, something they say has never before been observed in the country.
These fire-generated thunderstorms create their own weather, including strong winds and lightning that can spread flames unpredictably and ignite new fires far from the original blaze.
The cloud formed amid one of France's worst wildfire seasons in recent years, driven by prolonged heatwaves, dry vegetation and strong winds.
The report also notes that such clouds can loft smoke into the stratosphere, where it can persist for months and affect air quality far from the fire.
