The fires are horrible.
Are they happening because they’re not thinning forests or what?
I think fires in Spain are worse right now too.
I live in a tornado prone area, so the green skies are fairly common here.
The CA fires in this instance are mostly grass and brush fires driven by high winds. Embers ignite the structures.
I was once “in front” of a field fire driven by, oh, maybe 15-20 mph winds, in very dry conditions. That was bad enough. The flames were maybe 20 ft. high. We only stopped it when it got to an area of (thankfully) mowed grass. Can only imagine same at 40-50 mph, or more.
The Sonoma/Napa County fires were initally primarily grass fires. There is some forest land up over the mountain between Santa Rosa and the Calistoga/Napa areas. But it was grasses and weeds that grew large in the spring/summer with heavy rain, and dried out. Heavy winds on Sunday, October 8 caused tree/limb falls and those snapped power lines. Those same winds then fanned the flames rapidly. Some folks woke up to homes on fire. The damage in Santa Rosa was due to mostly trees between homes, but the reason for the fast initial spread was dry grass and wind.
