In Northern California, the Carr Fire is burning so large and so hot that it is forming pyrocumulus clouds. These mushroom-shaped clouds are formed when extreme heat from burning fires pushes air up rapidly and moisture from the burning plants evaporates which condenses onto the smoke particles.
Point is, the wildfire has basically developed its own weather system. The clouds could cause lightning and push blowing wind in different directions. Ironically, some fires that produce these types of clouds can be put out by rainfall that it creates.
Unfortunately, that scenario seems unlikely with the Carr fire. Six people have died and at least 19 have been reported missing. It has burned nearly 100,000 acres.
