Damage assessment teams report 96 homes destroyed in the Blue Cut Fire

(UPDATED at 9:39 a.m. PDT August 20, 2016)

There was very little growth of the Blue Cut Fire on Friday. As on Thursday, the east side of the fire was fairly quiet, while there is still fire activity on the west side, especially east and southeast of Wrightwood.

The incident management team is calling it 37,020 acres. On Saturday morning they revised upward the estimate of the number of structures destroyed, to 105 homes and 213 minor structures. Some evacuations are still in place.

CAL FIRE Public Information Officer Daniel Berlant reported this afternoon that Damage Assessment Teams estimate that 96 homes and 213 outbuildings have been destroyed in the Blue Cut Fire.

The fire has burned approximately 39,000 acres north of San Bernardino, California, according to the incident management team.

On Thursday the spread of the Blue Cut Fire north of San Bernardino in southern California was limited to the west side. According to the incident management team led by incident Commander Rocky Opliger, the growth added about 5,300 acres, bringing the total up to 39,000 acres.

The expansion occurred:

  • on the north side in the flats southeast of Phelan,
  • east of Wrightwood near Highway 2,
  • in the remote mountainous area on the west side, and
  • near Lytle Creek on the south side of the fire.

The east side of the fire has been relatively quiet for a couple of days.

A Red Flag Warning is in effect for the fire area Friday until 9 p.m. this evening for 15 to 25 mph southwest to west winds gusting to 35 mph during the afternoon and evening. Relative humidities will be 10 to 15 percent.

The fire started August 16 and grew to tens of thousands of acres quickly. Numerous structures were seen burning on live television, but no information has been released about how many were affected.

The incident management team expects the fire will continue to move to the north, northwest and northeast towards Wrightwood, Victor Valley, Phelan, Baldy Mesa and South Hesperia. Evacuations are still in place.

The Blue Cut Fire northwest of San Bernardino continued to spread Wednesday. The additional growth was on the northwest side where it reached Highway 2. And, on the north side it expanded a small amount at the base of the mountains and in the high desert flats toward Phelan. Evacuations are still in effect.

More accurate mapping on Wednesday resulted in the incident management team reducing the mapped size from 30,000 to 25,626 acres. After the growth of the fire yesterday, this morning they are calling it 31,689 acres.

Northbound Interstate 15 has reopened, but the southbound lanes are still closed. CALTRANS information about road conditions. UPDATE at 11:42 a.m. PDT August 18, 2016: Southbound I-15 is now open also.


(UPDATED at 10:18 p.m. PDT August 17, 2016)

The U.S. Forest Service has reduced the reported size of the Blue Cut Fire northwest of San Bernardino. At about 7 p.m. Wednesday they said more accurate mapping shows that it is now at 25,626 acres, down from the 30,000 figure released about 12 hours previously. They did not specify when that new assessment was valid — if it was based on a perimeter from Tuesday night, Wednesday afternoon, or some other time.

It had occurred to us that many sections of the perimeter were depicted as being too smooth and straight, rather than almost randomly jagged like the northwest section that was mapped by an infrared aircraft Tuesday night. (This comes from a guy, moi, who used to spend a lot of time mapping fires.) Since that IR flight the fire has grown by at least several thousand acres as shown in the satellite data in the map below. There is a report that it has either reached Highway 2 on the northwest side, or firefighters are burning out from that highway.

When a NASA satellite flew over the Blue Cut Fire at 1:30 p.m. PDT on Wednesday, it detected additional fire growth beyond the perimeter that was mapped at 11 p.m. PDT on Tuesday. The red squares on the map above outside the red line represent approximately 2,500 acres. Early Wednesday morning the incident management team was calling it 30,000 acres.

The additional growth was on the northwest side spreading toward Wrightwood and Phelan, and on the south side near Lytle Creek.

The U.S. Forest Service reports that the Blue Cut Fire at Cajon Pass has now burned 30,000 acres.

The red line was the perimeter of the Blue Cut Fire at 11 p.m. August 17, 2016. The white line was the approximate perimeter at 3:47 p.m. August 16. The Pilot Fire is on the right side of the map.

The Blue Cut fire continued to spread aggressively as darkness fell Tuesday night forcing 82,000 residents to evacuate. The fire started at in Cajon Pass near Interstate 15 at about 10:30 a.m. on Tuesday and rapidly spread into the brush. It is now 13 miles northwest of San Bernardino and has threatened the communities of Lytle Creek, Wrightwood, Baldy Mesa, Phelan, and Hesperia.

In addition to Interstate 15 the fire has crossed Highways 138 and 173. Officials closed I-15 and Highway 138, which made it difficult for residents to evacuate.

The live streaming video shown by Los Angeles television stations Tuesday included images of multiple structures that were destroyed including the Summit Inn, a well known local landmark along Interstate 15 in Cajon Pass.

At about 11 p.m. on Tuesday the U.S. Forest Service said the size was estimated at 18,000 acres, but with the data from an overnight mapping flight it is likely that an update Wednesday morning will put it at closer to 25,000 to 30,000 acres.

The weather forecast for Wednesday, which includes a Red Flag Warning, is not good news for firefighters. The temperature will be in the high 90s, the relative humidity will be 3 to 10 percent, and the wind for the next two days will be out of the south at 10 to 20 mph (depending on the exact location and day/night) with gusts of 20 to 30.

The Fire Behavior Analyst on the fire said “the brush is extremely dry, basically dead”.

CAL FIRE reports the Blue Cut Fire in Cajon Pass in southern California has grown to 15,000 acres.

The USFS reported that on the Blue Cut Fire today six firefighters became entrapped while defending homes and assisting evacuations in the Swarthout Canyon area west of Cajon Pass. The six firefighters were part of two San Bernardino County Fire engine companies assigned to the area northwest of Cajon Blvd.

The firefighters were able to shelter in place within a nearby structure, but two firefighters sustained minor injuries. Both firefighters were transported to a local hospital where they were treated and released and are now back on the fire line defending structures. One SBCoFD fire engine sustained moderate fire damage.


(UPDATED at 7:18 p.m. PDT August 16, 2016)

The Blue Cut Fire that started in Cajon Pass in southern California adjacent to Interstate 15 has continued to grow rapidly and is now estimated at 9,000 acres. There is imminent threat, the US Forest Service says, to public safety, rail traffic and structures in the Cajon Pass, Lytle Creek, Wrightwood, Oak Hills, and surrounding areas.

Evacuations are in effect for 34,500 homes and 82,640 residents.

Interstate 15 is closed in both directions.

(UPDATED at 6:05 p.m. PDT August 16, 2016)

At 5 P.M. the USFS reported that the Blue Cut Fire was 6,500 plus acres with 700 personnel on scene, 57 engines, 8 crews, 8 air tankers, and 2 Very Large Air Tankers (DC-10s). Additional firefighters and equipment are on order.


(Originally published at 2 P.M. PDT August 16, 2016)

The Blue Cut Fire started in Cajon Pass west of Interstate 15 at about 10:30 a.m. on Tuesday and rapidly spread into the brush. The Interstate is closed in both directions.

Several media outlets are reporting that one or possibly two fire engines were overrun by the fire and the firefighters left the trucks to take refuge in nearby residences. There are reportedly no injuries but ambulances were seen near one of the engines in live video of the fire.

The San Bernardino National Forest reports that there have been two minor injuries to firefighters. It is unknown if the injuries were related to the burnover of the engines.

The San Bernardino County Sheriff has declared a mandatory evacuation for all residents in the community of Lytle Creek which is on the west side of I-15.

NBC Los Angeles and ABC7 occasionally have streaming live video of the fire.

A freight train in Cajon Pass stopped and the crew evacuated, according to NBC Los Angeles. There is no report of the cars on the train burning.

Cajon Pass is infamous for frequent fires and strong winds that spread the fires rapidly.

  1. How close is the fire burning in Lytle Creek area to Etiwanda Perserve? There are homes right south of Ridge Line.

    1. No Karen
      The fire crews used Apple white campground, the main road, & Lytle Creek, as a firebreak & saved the fire station, Community Center
      & Church, Mtn. lakes Campground, Scotland Store,
      & ALL of the Homes & Cabins.

  2. One interesting feature I noticed on the InciWeb map released a few minutes ago.


    There is a rather obvious distinct unburned “V” in the middle of this present Cajon Pass Fire map all the way to the top of the ridge to the mesa. Then I remembered last year’s “North Fire” which the media dubbed “Carmegedon” because of the colateral damage on I-15. Had that not burned back in July 2015, can you imagine how massive the fire front on top of the Mesa all the way to Victorville ?

    Here is Bill’s map from last year and you can compare it to today’s Blue Cut Fire map


    1. Nice catch Kevin! 1 year old rough doesn’t burn well. We see a similar result in the Southeastern US where wildfires run into recent prescribed burns and either go out or a great reduction in intensity.

  3. I’m just glad those six firefighters made it out ok.

    My understanding is that they were trying to get people who did not want to evacuate out of the way.

    At any rate, as someone who has chosen – voluntarily – to live in the urban wildland interface, I sincerely hope that no firefighter ever risks (or is pressured to risk) his or her life to try to save my house. Houses and all things contained therein are in the end just stuff. Stuff can be replaced. People cannot.

  4. Here is an idea. How about all of those who are complaining about the FS response to the Blue Cut fire, become volunteer firefighters with Cal Fire. After fighting a few of these fires my guess is that your opinion might change. Armchair quarterbacks always make the most profound statements

  5. For those not familiar with this area, it has not seen real normal rainfall for at least 15- 20 years. It is a transition zone between the high desert and the inland empire. I was born and raised near Devore. Hiked and off roaded the area extensively. Even during near normal rainfall years, in the summer it is tender dry. Historically fires have swept thru the pass fairly regularly.
    What has changed is the amount of people living in the area.
    Perhaps regional fire officials will now realize that because of development, they need to be not only more proactive with enforcing fire safety regulations ( brush removal, domestic water tanks, fire resistant building and landscape materials), but also more aggressive when there is a fire.

    Fires that start in an area where hundreds of people drive by and see it, should never have gotten out of control.

    1. Quercus/Oak – a couple of points and questions for you:
      First, where does the responsibility lie for County Planners/Mortgage lenders/Insurance agents and Homeowners fit into your equation? Seems like those that allow/fund building in fire-prone areas have responsibilities at all of these levels.
      Next, you state that this fire “should never have gotten out of control.” My questions: are you a trained and qualified firefighter? At what level? Ever made IA (that’s Initial Attack for the uninitiated!) on a wildfire under those fuel moisture, terrain and weather conditions? Ever had the responsibility for other firefighter’s lives resting on your shoulders in incredibly dangerous conditions? Your comment is easily made, but lacks credibility if you aren’t speaking from a base of training and experience in the business.
      And my last question: as a Taxpayer, are you willing and able to bear the tax burden to staff a Wildland Fire Organization that can be “more aggressive when there is a fire” (your words again)?
      This Montana Boy is just asking.

    2. The forest service is always slow to call in air support.
      Had they pounced on the original 2 acre fire next to the highway I wouldn’t have Lost my home in Lytle Creek.
      The firemen pulled all the resource out of the canyon earlier today & left no personnel for structure protection.
      If it was Yorba Linda or Beverly Hills they would have structural protection

      1. Disappointed Resident Bob,
        Have you ever seen a fire flash before? Under conditions like this, that fire can be out of control within 10 minutes. There is a lot of new grass that has grown over from last year’s fire that is dried out, it’s like gasoline for a fire. This fire was out of control before any units could have a chance to respond. The loss of your home is unfortunate, but those fire fighters would have been cut off completely had they stayed to protect those structures.
        Yorba Linda and Beverly Hills have a completely different topography and level of development so its not really fair to say the fire fighters don’t care about your area, in fact its shameful. They wouldn’t be putting their life on the line if they didn’t care. As a side note, if residents would evacuate like they are told to do the fire fighters could spend more time protecting structures instead of saving stubborn residents that can’t follow directions.

      2. There are a number of other things you need to look at here. Even with all the modern day equipment like the sophisticated 747s and other large bombers and helicopters, they cannot fly in hurricane conditions in low hills, ridges and valleys accurately and safely. Aside from that, many resources and personel have been on other fires like Soberanes Wildfire up at Big Sur. On that fire which I have been following, it was also mentioned that planes would have to be taken from Big Sur and moved to the south for the Bluecut Fire. They had to pull off equipment and planes not only from that fire, but perhaps also the other Chimney fire by Hearst Castle which is another intense fire, not to mention the Sierra Nevadas and Northern California again. You cannot blame the authorities. Some crews are also still mopping up after the Pilot Fire just to the east of Cajon Pass.

  6. I have always maintained that when a new house is built in or near the forest anywhere .There should be a built in Fire Curtain .ringing the entire house and covering the area around the house for at least 1000 yds .. It is a lot cheaper than replacing the whole house and anybody that might be killed or injured.and its very simple to do all you need is about 20 fire nozzles pointed in alternate directions a lot of fire hose , and if you don’t want to put in a dedicated tank to supply the water and you have a pool , There is your supply for quite a while depending on the size of the tank ..Vewy Simple Vewy easy . Fire comes you set off the curtain and bug out ..and hopefully return to a soggy but otherwise safe house

    1. And all of this water will come from where …..? Do some simple hydraulic calculations on gallons per minute times the number of nozzles, then factor in the evaportaion rate from extreme temps, and you’ll understand why homes burn in spite of the FF’s best efforts.


  8. Here I go again. Air conditioned soft chair quarterback (ACSCQ). Many may want to replace the C and Q with a H and O. Reported that “someone” cancelled all or part of the initial air tankers responding?
    August, drought, Cajon Pass, potential, life threat, “HELLO” out there? As the R-3 folks on flood duty, California is just now entering the peak of fire season, which will last until? Buckeye tree leaves have turned brown.

  9. Wondering why so many homes threatened while myself and at least 15 type 6 engines at least two water tenders and a few type 3 engines are sitting here in region 3 with heavy monsoons and low fire danger?
