Sad, such lovely area up there. When I lived in California and felt like shit I would fuck off and drive through Sonoma County, find a hill that looked like no people bothered to hang out, and just chill in the silence and stargaze.
Looks like they are having a bad time up there, and there are predicting Santa Ana winds.
Do wildfires usually move this fast? Outbreak to "Sonoma County burned down" in less than a day is hard to fathom.
70MPH sustained winds, 20% or less humidity and no rain for 3-4 months. Everything is dry as tinder, infinite oxygen supply and the stuff gets so hot that the trees explode. Fires like this can move 20 miles a day. Laguna Hills, 1993 listen to the times and watch that sucker move. This was about 20 miles from where I was living at the time. It blew right over I-5 and went right through the houses along the hills.
Yeah they can move very quickly; especially around mountains due to wind effects. Plus wildfires that get large enough tend to influence the atmosphere around them (i.e. coupled fire atmosphere dynamics), making their movement even harder to predict. Though the research in this area is promising! Bonus: research in the journal of combustion which is just a fun place to browse. I was living within 2 miles of the Sand Fire last year, and it was insane and terrifying how quickly the fire line moved. Nothing like laying in bed and seeing a fire-tornado on the ridge out your window. Luckily I had a go bag by the door, so leaving quickly was easy, and the fire didn't reach my place. Same thing happened again a couple months ago when the La Tuna fire was within 2 miles of where I moved to, ha. This state is determined to almost burn me down.
