The wind shifted during the day, and by mid-afternoon the sky near where I work was considerably clearer—even though the fire seemed to be getting closer.

Mt. Saddleback viewed from Tustin foothillsLenticular Line (large)Some geography: The Santa Ana Mountains run parallel to the coast, and form the northeast border between Orange County and Riverside County. Here are a couple of photos from older blog posts showing the hills and the mountains in the background (though from very different angles).

The fire “broke out”* in the foothills on the western side of the mountains. One side went straight over the line of hills and down toward the flatlands, threatening homes in northeastern Irvine last night. That was stopped, but it continued along the canyons to the end of this set of hills, and last I heard had reached the edges of neighboring Lake Forest.

I think the front may have gotten within 4–5 miles of where I work, though we couldn’t see anything but smoke in that direction until late in the afternoon. Every so often I’d wander over to a conference room that normally has a clear view. Off to the northeast, everything faded to brownish gray. It faded to the southwest as well, but at least I could see silhouettes of the hills in the opposite direction.

I did, however, watch ashes floating by horizontally, 4 stories up.

Toward mid-afternoon, the wind (and fire) shifted, moving the worst of the smoke plume away, and outlines became visible. I took this one around 5:30, and you can just see the (likely) charred and smoking hills. (Notice also the orange balloon off toward the left.)

Smoking Hills

With all the smoke in the air, the sunset colors were intense. As the sun sank, it was a brilliant orange.

Orange sunset

Magenta sunAs it neared the horizon, dipping deeper into the layer of smoke, it turned almost purple, and was dim enough to look at directly. (Not that I stared—I’ve seen Pi after all!)

We got a break from the wind for several hours, which just ended minutes ago.

*Reports are that it was arson. What the hell is wrong with people who do this sort of thing? It’s not enough to set a bonfire, or even just burn down one structure—you have to burn down 15,000 acres of wilderness and possibly people’s homes?

Fire map as of 8:00 AMNo 3AM evacuations, though we’re several miles away from the danger zone anyway. The Santiago fire we spotted yesterday was stopped before it crossed into suburbia, but judging by the OCFA map it was a near thing. Now it’s burning southeast, into the hills and toward the canyons. Some of which are inhabited. (Yes, there is a rural Orange County.)

Downed TreeWe got some pictures of the fallen tree this morning. It managed to rip up a chunk of grass and displace a plastic divider, but it doesn’t seem to have damaged the walkway or stairs.

The winds are still going, which made the drive this morning… interesting. Leaves skittered across the road, swirling in dust devils. Some eucalyptus trees looked like they were bending at at least a 30° angle (and back again). My office turns out to be directly in the path of the smoke plume, which made for an odd view as I drove into it.

Passing into a smoke cloud

I’ve got some photos of a sepia sky, orange sun, and palm trees with all their leaves on one side, which I’ll try to post tonight, though it looks rather like the photo I posted during the October 2003 fires.

Smokey Spectrum

When I got to work, a few ashes were floating to the ground. I’m sure some of them managed to get into the car when I opened the door, which is rather annoying. There didn’t seem to be that many of them on the ground, until I noticed movement on the pavement. The ashes might look light-gray in the air, but they managed to blend in perfectly with the asphalt. That, and the wind seems to have blown most of them up against the curbs, where there’s a solid layer of ash.

The building, normally an off-white color, looked decidedly beige in the orange light. Everything looked faded. Well, almost everything. The iceplant around the parking lot edges looked greener than usual. It makes sense, since it’s normally bluish-green, and the orange-yellow lighting would cancel out the blue. Inside, the smell of smoke has permeated the building.

Update: Added photos.

I drove out to UCI on my lunch hour, and got my first view of the newly-completed Student Center. There are actually some parts of the building left over from the previous one, but the whole exterior is new. Then I remembered a photo I’d taken of the old Student Center, back when I was attending the school, from the top of what was then the Humanites Office Building, now Murray Krieger Hall. Since I had extra time on parking, I decided to see if I could match the shot.

Here it is 10 years ago:

No Parking sign… in the middle of the lawn.Ordinarily, there wouldn’t be anything odd about this sign. But look at the placement.

Why do they need a No Parking sign in the middle of the lawn? It’s a new sign, too—they just redid the entire lawn last year.

Seriously, I don’t think they’re going to have much of a problem with people parking on the lawn in front of an office building in Irvine.

Come to think of it, though, this is only 50 feet or so from the crosswalk warning device.

I wasn’t expecting to see more after my last post on lenticular clouds. As I said, they’re (usually) rare in this area. But as I left the office Friday evening, I pulled onto the freeway and nearly freaked out at what I saw: A line of three smooth, layered clouds running above the ridge of the mountains to the north of Saddleback, and two more less-defined clouds picking up south of the peaks. I took the first exit and headed for a spot where I knew I could get an unobstructed view: a park in the Quail Hill area. (Knollcrest, I think.)

It was near sunset, and I was in a hurry to get some photos (not to mention a better chance to look at them!) before the light faded. You can see that the sun had already dropped behind the hill on which I was standing.

If you look at the horizon in the wide view, near the left at what looks like the base of the hills, you can see the orange balloon at the Great Park. I’m fairly sure they’d stopped taking people up by then, though I did see it airborne during my walk at lunch.

I’ve enhanced the contrast on these next few images, all cropped from the same photo to show close-ups (relatively speaking) of the three clouds:

I’m going to do something unusual here, and post an original-resolution copy of that contrast-enhanced photo, just ’cause it’s so cool. It compressed really well, to 170K, but beware—it’s still a 2,567 pixel–wide image.
