Of course I do have perspective.  When I consider the reason I am experiencing this "problem" it is hard to get too upset about my circumstances.  Others are dealing with much more serious issues.  But it is remarkable that the fires out west are having that big of an impact here.

 

:ubetcha:

 

It's cleared up here, the winds are taking the smoke from the fires to north of us in an easterly direction.  Who knows what's going to happen, the fire season is far from over.

The skies were clear again today but this time we have a nice blue sky.  So I'm going out tonight.

We are finally down to about 50 on air quality. Best skies in about a month. I could feel the sunshine on me today.

We're still at 157 on the 2.5 micron index.
The sky is blue though, so a patio view is on tonight's schedule.

We are at 49 on the 2.5 micron index, but skies are still white here with upper level smoke.  Probably losing 2.5 to 3 magnitudes at the zenith.  Viewing won't be worthwhile.  If it's like yesterday, the sun will look a full moon brightness as it sets.

The satellite showed the fire having crossed the villages of Camp Nelson and Ponderosa, but this Visalia Times Delta article says the fire fighters managed to save the houses there. Nevertheless 150 structures in smaller settlements were lost.

Creek fire is now almost 272,000 acres with 25% containment.  The containment in the populated zones has been effective.  Fire seems to have jumped in the past 24 hours on the north end with a new string near Cora Lakes.  Looks like the center of the northern line is reaching Norris and Jacka$$ Lakes.  I assume burning will continue up there until the rains come.  

 

The Creek fire is now at #8 of recorded largest in California...behind four others this year, only two of which are near containment.  The SQF at 133,000 acres would have been well into the top 20 largest known California fires only a few years ago, but isn't even in the top 20 yet--unfortunately that will probably change next week.

Have had a fair bit of ash today.  SQF (Castle Fire) has broken through broadly and deeply to the west.  Looks like the opportunity to contain that one in the short term has passed.  Now the question is how far it will extend north and south on the western side of the range.  How many more hops will it make?

 

The way things look, eventually, nearly all of the western Sierra conifer ridge and drainage areas are likely to burn off the standing deadwood over the next several years.

It looks like the fire is slowly backing down through Garfield Grove.  It is almost to the South Fork Grove.  I assume that it is good data!!!

 

Looking at the Cal-Topo site you can check fire history and get all the fires since 2000.

 

https://caltopo.com/m/176F

 

If you go up and down the Sierra....there is MORE unburned forest than burned.  And really very little forest that has been burned twice.  It looks like the Sierra will keep burning for at least two or three more decades.

You can get "California Fire Perimeters (1878-2015)" on the left pannel here https://ia.cpuc.ca.gov/firemap/

 

The problem is that history doesn't tell much, as the fires involving trees have gotten more frequent, bigger and hotter. Part of it is tree kills by the recent 2011-2016 drought. But that is only part of the story as LA had some massive burns even before that.

I had looked at a map showing the travel of the smoke sometime early last week. It seemed to be headed almost straight eastward. It seems wind direction changes shifted it a bit southward as now its creating a haze here in far west Texas. Noticed that the Moon was kind of orange last night and now the distant mountains are invisible. This reminds me of the massive fires in Arizona a few years back. At least, as of now, the smell of smoke isn't present- yet.

Everyone caught in the mess, be careful.

Here in West Texas, 1500 miles or so from most of the western burning, the sunrises and sunsets have been spectacular!  Their beauty, of course, has the cast of sadness when we consider the unprecedented fires our western citizens in Colorado, Utah, California, Oregon and Washington have endured, after unprecedented droughts.  This area of Texas, the Llano Estacado, is one of the flattest places you'll ever see on planet earth 993 meters above sea level.  I was driving my daughters to school yesterday, and a deep orange sun, huge and oversized as it and the moon are when very low, was cresting the eastern horizon, half-sized.  Unfortunately, we were in a hurry and I couldn't stop.  By the time I'd dropped my second daughter off at Middle School, the sun was already too high and bright to look at easily, but on our drive in, one could look straight at it, naked eye, its rotund semicircle slowing climbing over the edge of our line of sight.

No one knows the health effects of breathing this stuff for weeks at a time, but your 2nd picture is how the sun looked when it was on the meridian at the worst of the smoke for us.

2.5µ particle counts were above 500 for many days.It has declined to ~100 now, but, to put that in perspective, a count of 30 is considered unhealthful for some people.

And prior to the fires, we averaged ~10-15 where I live.

Around a week ago, I saw the Sun look like his second photo too, and I'm on the East Coast.  Yeesh.

 

But according to the local weather forecasters, all the smoke was really high up in the atmosphere, so I'm assuming this isn't as much of a health issue as it is out West.

I live about 275 miles south from Sacramento and today is the best air report I've seen in a long time. 

The 2.5 PM is only at 26 right now! 

I work nights so I won't be able to enjoy this tonight :(

As the Sun sank towards the horizon on Tuesday night, when the smoke returned to Pennsylvania, it was very red.  Here's an iPhone shot that I took when it was still higher in the sky.  The Sun was deep yellow in hue at the time.

Starting this weekend, almost all of Northern California is under Red Flag warning. Hot and windy. Diablos & Santa Anas. This fire season has been brutal.

 

For our CA neighbors, take care and stay safe.

Here's the sun, a few days ago.  Thankfully; a low pressure system is here with winds that have cleared the skies here.

Unfortunately, you may be right, but as of this moment, much of the State has a good AQI,

and most of the fires have been contained.  My source is:

https://fire.airnow.gov/

which is realtime, so might change by the time someone reads this.

 

Red Flag refers to events which may occur, not those that have occurred.  Can you cite

the source?  Is it CalFire?

 

The forecast is for it to be hot and dry in Northern California.

 

I'm hoping for the best.

CalFire, NWS, and PG&E that’s also warning of eminent power shut offs.

The red flag warning was right. There are new fires in the northern Napa valley. The biggest of them Glass Fire grew to 2500 acres. The Bay Area is filling up with bad air again.

If the FIRMS satellite mapping is correct, this thing is already 20,000+ acres and has reached the city limits of Santa Rosa.  Hard to tell if this is accurate because that is MODIS rather than VIIRS.

So sad. It looks like the Glass Fire is burning the area that was left between the 2017 Tubbs and Adobe/Nuns Fires into Santa Rosa. It just looks like the fires very systematically attack anything that has not burned recently. While I like the idea of controlled burns in the low season it is unclear how to do that on a scale that would make a difference with these recent monster fires. This year wasn't a particularly strong drought, but somehow vegetation must have reached a threshold.

36000 acres burned in the Glass Fire. Just one day. Now for people further East this won't create as much ashes as the Creek Fire (now 304,640 acres and sixt biggest in CA history)  which has a lot of big dry trees burning instead of the typical chaparral and grass. The SQF complex in the southern Sierra has slowed down at 150k acres. The August fire complex in the northwest keeps slowly growing at 878'000 acres. Depressing.
