Like people, wildfires aren’t born coherent or fully formed. They rarely have one direction or one goal. Fires are fluid and disparate, made up of smaller blazes and embers, some of which might merge into irrational explosions or veer off in different directions. (Scientists have dubbed this odd meandering, not “fire movement” or “fire patterns,” but “fire behavior”). Today, Los Angeles, like Sonoma County, is on fire.
