They're evacuating homes just outside of LA as fire comes down from the hills.

The good news is they aren't too worried about the smoke from the fires because the LA smog is already so bad adding a little forest fire smoke doesn't make much difference.

Brazil's worst month ever for forest fires blamed on human activity

"September saw more fires than any month on record, as experts say uptick is due to expansion of agriculture and reduction of oversight and surveillance"

A Warmer World Is Sparking More and Bigger Wildfires

http://e360.yale.edu/features/the-evide ... -wildfires

The increase in forest fires, seen this summer from North America to the Mediterranean to Siberia, is directly linked to climate change, scientists say. And as the world continues to warm, there will be greater risk for fires on nearly every continent.

Evidence is becoming more and more overwhelming,” says Flannigan, that climate change is spreading fires around the world. Globally, the length of the fire weather season increased by nearly 19 percent between 1978 and 2013, thanks to longer seasons of warm, dry weather in one-quarter of the planet’s forests. In the western United States, for example, the wildfire season has grown from five months in the 1970s to seven months today.

The number-crunching now shows an increased risk for fire on nearly every continent, says Flannigan, though most of the work has focused on North America, where there is a larger pot of funding for such research.

I was just in Napa Valley this weekend as wife wanted a get-away. We went to a winery as recreated Medieval castle. Very nice recreation. My wife pointed out how beautiful the Napa Valley hillsides were with their rows of grapes and then the typical hillside shrubs that go up to the peaks. Seemed unusually warm to me and the vegetation seemed to look the part. The grape vines are obviously drip irrigated, so the land can look dry but the vines are fine.

I now always check the fire maps before setting out on trips. Only a day-and-a-half afterwards, we wake up to a Red Dawn and my wife comments how beautiful is the sunrise! That's the difference between an optimist and a realist (going on to pessimist, perhaps). Valley is in flames overnight, evidently.

Here in San Jose, we are in the smoke plume from Napa and Sonoma and Yuba counties. The air quality is poor and they have reccomended that we keep our houses shut up and stay indoors. The wife and I woke up coughing and quickly shut the doors and windows.

Fortunately the grape harvest and crush, which began in mid-August, is pretty much complete. There are some late season grapes which may be affected and the wine may acquire a smoky taste, but relatively few. The heavy rains had rejuvenated the vine roots and caused a bumper crop of grapes but there was so much moist air and heavy dews that growers have struggled against mildew all Summer.

we try to spend a week or two in Napa/Sonoma area right after harvest each year. I guess it was a good thing we couldn't this year. I wonder how many of the vineyards will be affected? May not hurt this year's crop of grapes but some of those vines are very, very old which accounts for the grape quality. Anyone of the big commercial vineyards supplies grapes to a host of wineries. It's a big part of the economy for this part of California so would be a shame to see it damaged significantly.

We had the same problem last fall; two weeks of smoke from nearby forest fires. Rather than pump smoky air through the ventilation system, I bought a couple of 20x20 hepa furnace filters, taped then to the back of 20x20 box fans and kept them running on low speed. Worked quite well.

SoCal, too:

Wildfires now burning homes in Anaheim Hills, SoCal.

This is already one of the worst fire days in California history, and getting worse.

Those fires really exploded quickly, from 200 acres to 20,000 in hours and now ~ 45,000; at least 1500 homes destroyed in last 24 hours:

https://mobile.twitter.com/PeskyHeart/s ... 5430663171

http://www.latimes.com/local/lanow/la-m ... story.html

The vast devastation over just a few hours made this firestorm one of the worst in California history, with Gov. Jerry Brown declaring a state of emergency.

No deaths have been reported, but there have been injuries and people are unaccounted for, said Janet Upton, a spokeswoman for the California Department of Forestry and Fire Protection. She could not estimate the number of injuries.

One of the raging fires had Santa Rosa under siege Monday morning, with a large swath of the city north of downtown under evacuation order.

The fast-moving fire jumped the 101 Freeway, forcing hospitals to be evacuated and, witnesses said, burning homes and businesses.

The area of Fountaingrove appeared to be particularly hard hit, with photos showing numerous homes on fire. The Fountaingrove Inn and a Hilton hotel also burned. Officials said homes were also lost in the community of Kenwood and at a mobile home park off the 101 Freeway.



Near total devastation Santa Rosa’s Coffey Park neighborhood where #TubbsFire reduced homes to ashes.

Fire Prevention.

I live in a forested area, but really near 'civilization'. It is clear that 'civilization' is not moving, but the trees may have to, although there is some back and forth between trees versus shrubs:

“What we’ve been advocating for quite some time is that the fire risk around here is with the grasses and the shrubs,” Dan Grassetti, who heads the Hills Conservation Network, told me. “We are trying to prevent the creation of more of that kind of vegetation, because it’s an enormous fire hazard.”

I also notice houses with shake roofs are still in my San Francisco Bay peninsula area. I wonder how these can still be allowed to exist?

So, what started so many blazes at the same time? Could be the urban-rural interface of trees and power lines. I live among trees and power lines, so I know exactly what this is all about. The trees are typically barely trimmed to clear the power lines, whether to save money or, far more likely, to avoid the wrath of pro-aesthetic, pro-environment people AND homeowners, perhaps.

"It’s real bad," Cal Fire Battalion Chief Marshall Tuberville told the L.A. Times. "This is an example of nature in control, and we are doing what we can, but we’re not being that effective at stopping the fire."

"Surface dewpoints, a measure of moisture in the air, were in the mid-upper teens, lower than values in Las Vegas or Phoenix," Erdman added.

"Imagine a wind-whipped fire burning at explosive rates," California Department of Forestry and Fire Protection Director Ken Pimlott told the AP. "This is 50 miles per hour. Literally, it's burning into the city of Santa Rosa ... burning box stores."

I opened up my house. You can still smell faint smoke, the air quality is all the way to "Moderate" and it was really a wash, after having cooked for two days with the house shut up, the food smells were noticeable.

Several of the fires are still mostly not contained. Too few emergency firefighters are engaged in property protection only, and frequently losing the battle to save a structure or a neighborhood.

Many people are learning the folly of owning a wooden-framed house nestled comfortably into the brush and trees.

Fortunately, I'm in the South Bay Area, Silicon Valley. Governor Moonbeam just interrupted my recording of my favorite cooking show with an emergency broadcast. But all the major fires are in the North Bay Area (wine country).

Again, I woke up with burning eyes and a cough. The air quality forecast for today is "Unhealthy". I'm shutting the house up again.

Those houses in Santa Rosa were built too close. Folks and insurance company should have been told. Cal Fire recommends " cutting or removal of trees between 150’ and 300’ of an Approved and Legally Permitted Habitable Structure."

Those homes were threats not just to themselves, but to the entire neighborhood. Your neighbors home is your fire hazard. It is just as combustible as a tree or dry brush.
Haven't you heard? I'm a doomer!
