Some new fires popping up today--some ignited by lightning yesterday. #GarnetFire on Sierra Nevada west slope is putting up a striking pyrocumulus plume (transitioning toward pyrocumulonimbus--a "fire-generated thunderstorm" cloud) under continued hot & unstable conditions. #CAwx #CAfire

Wir haben den Pyrocumulonimbus 2020 erklärt, die Mechanismen sind die Gleichen. In Frankreich war zumindest ein Cumulus dieser Art zu beobachten. Die Brände erzeugen ihr eigenes Wetter.

Nearly a week into devastating wildfires in France, officials said that firefighters had encountered a pyrocumulonimbus — a “fire cloud,” or a thundercloud created by intense heat. The phenomenon can spark new blazes and is “unprecedented in France,” officials said. Here's what to know.
Heat From France’s Wildfires Creates a ‘Fire Cloud,’ or Pyrocumulonimbus

Pyrocumulonimbus clouds are becoming more common here as well. They create fire conditions where you don't have a hope of containing a fire. Scary as hell.
📢 Two wildfires burning in the western United States are so hot that they are spurring the formation of “fire clouds” that can create their own erratic weather systems.

An interesting, if unfortunate, sight flying over Montana yesterday on the way home. Apparently a big wildfire sending plumes of smoke skyward. As it reaches high enough, the cold upper air causes the rising smoke to form pyrocumulus and pyrocumulonimbus clouds. #Wx

To process the chaos, I'm spending a few minutes each night stitching a news diary--embroidering tiny icons representing an important story of the day.
July was a bit of a whirlwind, and not just because of the pyrocumulonimbus clouds.
