7/28/2026

Summary

Fire Cloud Ignites

A pyrocumulonimbus fire cloud formed over the southwest France wildfire, the first ever recorded in the country.
The cloud generated lightning that ignited new fires away from the main blaze.
Erratic winds from the cloud accelerated the fire’s spread, which has burned over 420 square kilometers.
Lt. Col. Éric Brocardi said the climate-driven cloud can loft smoke into the stratosphere, potentially affecting air quality far beyond the fire zone.
