The photo above and the next three photos of the Holy Fire in Orange County, California were taken August 6 from the 747 Supertanker by Hiroshi Ando, Drop System Operator, Global SuperTanker.
The Holy Fire is in Holy Jim Canyon in Orange County 6 miles northwest of Lake Elsinore, California

Late Monday night the U.S. Forest Service estimated that the Holy Fire in the Cleveland National Forest east of Rancho Santa Margarita, California had burned approximately 4,000 acres, but that figure could change with more accurate mapping.
The fire started in Trabuco Canyon east of Holy Jim Canyon and rapidly ran up the very steep slopes to the North Main Divide Road at the top of the ridge. The latest rough mapping by the incident management team indicates that very little of the fire has crossed the road which is primarily on the top of the ridge. But better mapping in daylight will provide better information. That road is also near the boundary between Orange and Riverside Counties, and so far most of the blaze is in Orange County.

A brush fire in Trabuco Canyon in the Cleveland National Forest in Southern California has burned at least two cabins. The blaze started around 1:30 p.m. Monday near the intersection of Holy Jim Canyon Road and Trabuco Creek Road. In mid-afternoon fire officials estimated it had burned about 1,200 acres.
It is spreading up very steep slopes in the canyons on the west side of the Santa Ana Mountains, running up to the North Main Divide Road, an elevation change of about 2,600 feet. A Los Angeles TV station, ABC7, has had intermittent live video from a helicopter showing fairly intense fire behavior, with frequent fire whirls on the flaming front.
The fire is two miles east of the community of Trabuco Canyon, three miles southeast of Temescal Valley, and six miles northwest of Lake Elsinore.

The Mendocino Complex of Fires east of Ukiah, California has blackened more than 273,664 acres, becoming the second largest wildfire in the state’s recorded history if the size of the two fires in the “complex” are combined. Since we last reported on the fire two days ago it has grown by 120,000 acres, according to the numbers released by CAL FIRE Monday morning.

The Ranch Fire, north of Clear Lake, over the last two days has spread five miles east, one to two miles north, and three miles south. Sunday it spread into the footprint of the Pawnee Fire that in June of this year burned 14,000 acres west and south of Indian Valley Reservoir north of Highway 20. The blaze is threatening communities on the east shore of Clear Lake, including Nice, Lucerne, Pepperwood, Glenhaven, and Clearlake Oaks.
The other fire that makes up the “complex” is the River Fire west of Clear Lake. About three-quarters of the perimeter has been quiet recently, but it is still moving aggressively north, coming to within less than two miles of merging with the Ranch Fire to the north. The report by one local media outlet that they had already merged was premature.
On the two fires 75 residences have been destroyed and another 9,300 remain threatened.
Resources assigned to the fire include 432 fire engines, 89 water tenders, 15 helicopters, 57 hand crews, and 80 dozers, for a total of 3,781 personnel.
Nationwide on wildfires 558 hand crews, 186 helicopters, and 1,907 fire engines are assigned on wildfires, for a total 28,234 personnel including overhead and other firefighting resources.
Australia and New Zealand have sent 138 fire personnel to assist. They are currently deployed in California, Oregon, and Washington.
July in the state had the highest minimum temperature on record

There are many ways that a warmer climate can influence wildfires, causing them to burn more intensely. Higher temperatures can lower the relative humidity, lower the amount of moisture in the vegetation (fuel), raise the temperature of the fuel itself, and cause more powerful thunderstorms with lightning. But one factor that we don’t think about very often is that the heat can persist through the night, influencing fire behavior.
When today’s senior firefighters began their careers, they could usually count on fires “laying down” at night. The intensity and rate of spread would decline to the point where night shift personnel could more easily and safely “go direct”, constructing fireline very close to the edge of the fire.
During the month of July in California, many of the large fires continued to grow rapidly at night, which often required firefighters to drop back to a safety zone and simply watch, since there is little that they could do without putting themselves in harms way.
No surprise that CA has been getting warmer, but particularly striking is accelerated pace of nighttime warming. Large implications for human health (harder for human body to cool off) & for #wildfires (fires don’t “lay down” when temps stay warm at night). #CAwx#CAfirehttps://t.co/ATnz7u1J3B
Of course it is too early to say that this will be a permanent change, but in the last month a new record was set for California’s average minimum temperature; it was the highest since records have been kept. And this was not just a one-month event. The trend has been increasing since the 1980s.
Many of those senior firefighters have been known to to lament the trend in the last couple of decades of incident management teams declining to have a night shift. The justification of the teams was that it was not safe to have firefighters working at night because of snags falling, steep terrain, and other issues. After observing the nighttime fire behavior in recent years, the senior firefighters might now be less inclined to argue strongly in favor of night shifts, at least in certain geographical areas and weather conditions.

This is a flyover virtual tour of the Ferguson Fire burning in and near Yosemite National Park in California. The red line was the perimeter at 12:15 a.m. PDT August 5, 2018. The red shaded areas were intense heat at that time. The blue line is the location of the huge Rim Fire of 2013. The green line is the boundary between Yosemite National Park and U.S. Forest Service managed land. Recorded by WildfireToday.com August 5, 2018.
The fire has burned over 89,000 acres in Yosemite National Park, Sierra National Forest, and Stanislaus National Forest. On the north edge it has burned into the footprint of the Rim Fire that blackened 257,000 acres in 2013.

Astronaut Alexander Gerst tweeted these photos on August 3 of the wildfires in California, apparently taken from the International Space Station. He didn’t specify the date, but presumably they are very recent.
I’m not positive, but I think the photo that has multiple fires includes, from bottom to top (south to north), the Ferguson Fire at Yosemite National Park, the Mendocino Complex east of Ukiah, and the Carr Fire at Redding. The smoke farther north could be the Natchez Fire and blazes in Oregon. The other photo is most likely the Ferguson Fire.

California burning. These fires are frightening to watch, even from space. Here’s a shout-out from space to all firefighters on this planet, my former colleagues. Stay safe my friends! pic.twitter.com/y7PNmR006b
