A wildfire near Anderson Creek in British Columbia has produced massive pyrocumulus clouds, visible as cauliflower-like formations hundreds of kilometers away.The Anderson Creek fire was discovered by aircraft responding to another nearby blaze on July 23, 2026, and quickly intensified due to strong winds.

Meteorologist Matt Loney from Environment Canada explained that these clouds form when intense heat from fires creates convection currents, causing moisture to condense rapidly.Photos shared online show the towering clouds hovering over smoke plumes, with some images captured as far away as Coquitlam, 220 kilometers distant.

The phenomenon indicates extreme atmospheric instability, as the clouds grew vertically rather than horizontally, making them visible from multiple directions.Loney compared the process to opening a freezer door on a hot day, where cold air sinks while heat rises.These clouds contain particulates like burning embers and ash, which become visible before dispersing horizontally when temperatures stabilize.The event highlights both the intensity of the fire and the complex interactions between wildfires and weather patterns.Officials noted that 180 fires continue to burn in northern Ontario, emphasizing ongoing environmental challenges.
