The Yarnell Hill tragedy; examining the wind and topography

(UPDATE at 9:14 p.m. MDT, July 6, 2013)

We added this photo of the entrapment site on the Yarnell Hill Fire. The dozer line was punched in after the incident to facilitate the removal of the bodies, which were at the end of the line. The photo was taken by Wade Ward of the Prescott FD, and is used here with permission.

(Originally published at 8:53 MDT, July 6, 2013)

Robert Ford, who grew up in Prescott, studied some of the information that is available about the wind when the 19 members of the Granite Mountain Hotshots were killed on the Yarnell Fire June 30. His message is below, with a few notes from me [in brackets].


“A graphic showing the “safety zone” and shelter deployment site is here.”

[Note from Bill: the times in that article are approximately 6 hours in error. We were told by Carrie Dennett of the Arizona State Forestry Division that their office received notice that shelters had been deployed at 4:47 local time, Mountain STANDARD Time. But they were not in direct communication with firefighters. The information had to travel up a chain of command and may have been delayed. I have not seen definitive word on when the deployment took place.]

“A Google Earth rough approximation of the high res photo above is attached.

Approximate location of shelter deployment
Approximate location of shelter deployment. Google Earth.

Looking due west, eye altitude about 5400 feet. The approx. shelter site is 34.221416,-112.775796. The Landsat imagery was acquired last May; note the fuel, when compared to the Facebook photo above.

If you have Google Earth, it is also easy to duplicate the camera location of the time-lapse video (posted on your site) [embedded again above] purportedly shot from “Congress”; actually I’ve determined it was shot just west of the Date Creek Road (dirt – you can see the dust clouds from passing vehicles) just North of the intersection with Highway 89. The time-lapse video, looking N45E, shows the fire just cresting the ridge starting about one mile due Northwest of the shelter deployment site, then flashing to the right (southeast) along the ridge-line towards the deploy site. The smoke then obscures how the fire must have flashed over the ridge just 1500 feet west of the deploy site. In any event, the video shows how very rapidly the wind moved through the natural basin of the deploy site; probably aided by a natural venturi effect from the walls of the basin; also note that by the end of the video a trailing vortice formed off the ridge crest has actually moved the plume locally down (by 2000 feet !) to about the elevation of the Camera. It was an amphitheater of death for all of those brave men. This also explains why some men were found “outside” their shelters; that’s because a wind of unimaginable proportion, moving locally upward, lifted their shelters away.

Well thank you and you are very welcome to use whatever of this information you please. I have learned so very much from your site; it contains absolutely the best no-nonsense web coverage of this fire. In the event you wondered, I used to model the effects of wind on the topography surrounding astronomical observatories; but I never had to deal with a surface boundary condition as defined by a wildfire: that adds an order of magnitude of complexity to the simulation. I would like to presume the Feds will realize the importance of contracting a surface topography wind effect model for this fire, as a component of their investigation; If you have any say in the matter I am happy to recommend the best people; it’s not cheap as it requires supercomputer time.

Finally, I needed to relate that I grew up in Prescott; fighting fires was a rite of passage. You would have thought that by now the FS would have developed a weather-topography-fuel load model to deal with this sort of thing.

Well now they will do so.”

This location [above] is just off (east of) the trail on the ridge crest-line, and is located about 0.82 miles Northwest (as the crow flies; longer by trail) of the shelter deploy site (subject of my previous post). Now given the vantage point vector as due East, the plume appears to be moving southeast; thus the fire front (barely visible in the photo) is being driven directly towards Glen ilah.”


Follow-up from Bill:

A comment left on one of our posts by “lone ranger” found an article that included information provided by the National Fire Administration, which is the first I’ve head that they had anything to do with this incident. I would be hesitant to trust this information. The report says the firefighters initially took refuge in a burned area, the black, then left that site and deployed their fire shelters later in another area as they headed toward a ranch which was to be their safety zone.

There continues to be confusion about the times. This may be partly due to the fact that Arizona is not on Daylight Savings Time like most of the United States. They use Mountain STANDARD Time.

A blog called Cliff Mass posted a very clear and detailed explanation of the weather. His last line in the article:

A number of media outlets called the strong winds unpredictable and random. This is not correct, as shown by the information I provided above.

Chuck Bushey told us that once upon a time there were:

…Fire Behavior Service Centers in various regions, warning crews in real time about t-storms (or other events) heading their direction that they couldn’t yet see and getting them into the black. The Southwest use to run a FBSC with a qualified Fire Behavior Analyst (FBAN) but I think they dropped it as did everyone else.


Weather conditions during the tragedy at Yarnell Hill, and where do we go from here

We first wrote about the thunderstorm that may have contributed to the June 30 deaths of the 19 firefighters on the Yarnell Hill Fire, June 30 at 6:58 MST. But since that information is buried in a long article about the fire, and a little more information has emerged, we are summarizing the facts about the weather conditions that tragic Sunday afternoon. We also have some suggestions for providing firefighters with weather warning information that could save lives.

The formal investigation into the deaths, what caused them and any lessons to be learned, is just beginning. The results will probably not be known for many months. We will leave it up to the investigators to determine why it happened and what decisions were made before and during the incident. But the facts about the weather that day have already been recorded in various ways.

Carrie Dennett, a Fire Information Officer with the Arizona State Forestry Division, said the Arizona Dispatch Center received a call at 4:47 p.m. MST, June 30, that firefighters on the Yarnell Hill Fire had deployed fire shelters. The Dispatch Center was not in direct communication with firefighters on the ground at the fire. The information would typically have been relayed from the local Yarnell Hill Fire organization up through lower level dispatch offices.

Radar at 5 pm MDT, June 30, 2013 The pointer is at Yarnell, Arizona.
Radar at 4 p.m. MST, June 30, 2013 The pointer is at Yarnell, Arizona. WeatherUnderground.

The radar map above from WeatherUnderground at 4 p.m. MST June 30 shows a large thunderstorm cell north and northeast of the fire at Yarnell, Arizona. The pointer is at Yarnell. At 10:55 a.m., according to data from the MODIS satellite, the fire was approximately a mile or so north and northeast of the town, between the town and the approaching thunderstorm. At that time and until after 4 p.m., the wind blowing from the south-southwest and the southwest, most likely would have caused the primary spread of the fire to be toward the northeast.

Animations of weather satellite images that afternoon HERE and HERE, show the development and movement of the thunderstorm into the fire area. The red “X” and circle mark the approximate location of the fire.

Before and after 4 p.m. the cell was moving toward the southwest, and may have produced strong winds that changed the wind direction by 180 degrees (see below) and may have been the reason the fire moved into Yarnell. It also could have caught firefighters by surprise.

From 10 a.m. until 4 p.m. local time at the Stanton RAWS weather station four miles south of the fire, the wind was from the south-southwest or southwest, but between 4:01 p.m. and 5:01 p.m. it began blowing from the north-northeast at 22 to 26 mph gusting up to 43 mph — a 180-degree change in the wind direction.

Data from Stanton RAWS weather station, near Yarnell, AZ
Data from the Stanton RAWS weather station, four miles south of Yarnell, AZ, June 30, 2013

We were told by a spokesperson for the fire that the location of the firefighters when they died was between the fire and Yarnell, which would put them north or northeast of the town. Michelle Lee of the Arizona Republic told us that they were about one quarter mile southwest of Glen Ilah estates, “in the mountains”. Glen Ilah is on the southwest side of Yarnell. Anyone in that area between 4 and 5 p.m., who previously had the wind at their backs for seven hours with the fire moving away from them, may have suddenly and unexpectedly found the fire heading toward them at a rapid rate, pushed by winds gusting over 40 mph. Wind direction changes like this can be caused by strong outflowing winds from a thunderstorm in the dissipating stage.

At 5:01 p.m. the temperature was 95 degrees and the relative humidity was 17 percent. That, coupled with sustained winds of 26 mph with gusts over 40 mph, could have caused the rate of spread to increase to the point where it would have been impossible for any firefighting resources, in the air or on the ground, to implement any kind of effective fire suppression action, especially at the head of the fire which was moving rapidly toward Yarnell.

The Weather Forecast

A Type 3 Incident Management Team transitioned to assume command of the fire at 10 a.m. on June 30. That morning the fire had burned less than 1,000 acres. Incident Meteorologists from the National Weather Service, IMETs, are frequently assigned to large wildfires. While they are on site they can provide a great deal of very detailed weather information to firefighters, monitoring the conditions closely and in constant communication with the IMTeam.

It would have been unusual for an IMET to be assigned to a fire of that size on June 30, and with a small Type 3 IMTeam. The next morning, however, an IMET did receive an order to respond to the fire along with a much larger Type 1 IMTeam.

But even without an on-scene IMET, firefighters have the capability to request from the National Weather Service a special “spot forecast” for a fire, and at least two were provided before the fatalities occurred, one at 8:33 p.m. MST on June 29, and another at 9:45 a.m. June 30. The latter one, according to the information at the top of the forecast, was requested at 9:39 a.m. MST and produced six minutes later, a remarkably short turnaround.

The spot forecast for the morning of the incident predicted “isolated thunderstorm activity”, and, “Partly cloudy. A slight chance of showers and thunderstorms in the afternoon”. The predicted wind was “east winds around 5 mph…becoming southwest with gusts up to 20 mph in the afternoon”.

It is extremely difficult or even impossible for meteorologists to predict exactly where and when thunderstorms will occur, especially if they are “isolated”, or few in number. It is also difficult to forecast the exact wind speed and direction under any conditions.

Where do we go from here?

Firefighters need to know when there is a sudden change in weather conditions that can threaten their safety. Since it will never be possible to have an IMET at every fire, there needs to be a concerted interagency effort involving the National Weather Service and the *land management agencies, state, local, and federal, to develop a system to provide firefighters with the situational awareness information they must have to reduce the probability that they will be surprised by a life-threatening change in the weather.

Firefighter’s Emergency Situational Awareness Device —  FESAD

We may need new developments in hardware for firefighters so that they can receive weather warning data directly from the source without going through layers of bureaucracy. The military probably already has something like this, but I envision a device with a 7-inch display that could receive satellite transmissions anywhere there is a clear view of the sky. Each firefighter would not need to have a Firefighter’s Emergency Situational Awareness Device, a FESAD — just provide one for every fire. It could be based on a satellite phone, would have a GPS receiver (like in most smart phones), and be capable of receiving text and images. A deluxe version might also function as a satellite telephone, so that the firefighter could call the weather forecaster to get more information. The person sending the data to the fire would not have to know the phone number of the receiver, but would draw a box on a map and any devices within that box would receive the data, without bothering others that would not be affected by the warning. When the FESAD arrives at a fire, the user could have it send a message registering its location so that warnings for that area could be received. This would also alert the on-duty Remote-IMET to add it to their watch list.

Alert who?

Remote-IMET (R-IMET)

The warning data could be sent to the fire by an NWS forecaster always on duty with the primary responsibility to remotely monitor weather conditions near multiple fires. (The NWS already does this for the entire nation for severe storm, tornado, and hurricane warnings.) For fires, let’s call them Remote-IMETS. Some of the Geographic Area Coordination Centers already employ full time fire meteorologists. With the right software they could perform this function.

An R-IMET would have the technology available to instantly transmit text and graphical data about an emerging dangerous condition directly to those on the ground without relying on telephones to filter the information down through various layers. An R-IMET would not have time to handle all of the IMET duties normally performed by an on-scene IMET, but would concentrate primarily on issuing urgent warnings that could affect the safety of firefighters.

What if …. there had been a FESAD and R-IMET available for the Yarnell Hill Fire 

FESADs and R-IMETs could save lives.

The iron is hot

There is a great deal of national interest right now in the deaths of the Granite Mountain 19. If any new initiatives that would cost money are going to be implemented, our Fire Leaders must strike now while the iron is hot. There may be a small window of two to four weeks during which there will be some sympathy nationwide and citizens and lawmakers are open to enhancing the safety of wildland firefighters, even if it involves spending money.

An example of a rapidly closing window of opportunity is the movement for controlling gun violence after a gunman fatally shot twenty children and six adult staff members at Sandy Hook Elementary School in Newtown, Connecticut. If the administration and lawmakers had taken action quickly, meaningful legislation would have had a much better chance of passing. Instead, they waited months, and achieved little.

*A side note

It pains me to describe the federal fire departments as “land management agencies”. Organizations whose primary mission is to grow trees, clean campground toilets, or manage visitors, do not have at the top of their To-Do List, “Provide real-time weather warning information for firefighters”. We need a National Fire Service.

Sole survivor of Yarnell Hill Fire identified

Brendan McDonough

The only member of the Granite Mountain Hotshot crew to survive the Yarnell Hill Fire has been identified as 21-year old Brendan McDonough. Contrary to earlier reports that he had been assigned to move equipment when the other 19 members of the crew became entrapped and were killed, Mr. McDonough was serving as a lookout.

The duties of a lookout on a wildland fire are to observe the fire and the weather and to notify the crew about changes that could jeopardize their safety. Typically they find a high vantage point from which they can see both the fire and the location of the other firefighters.

In a briefing Tuesday, Prescott Fire Department Public Information Officer Wade Ward said Brendan, who is in his third season with the crew, did “exactly what he was supposed to do”. When he arrived at the lookout point he identified a trigger point for himself and decided that when the fire reached that location he would have to leave for his own safety. Later in the day when the fire reached that trigger point, he radioed the crew Superintendent, telling him that the weather was changing rapidly and the direction of spread of the fire had changed because the wind direction had changed. Brendan told him that he had to leave his lookout location and that if the crew needed anything to contact him. That was his last communication with the crew, after which he walked out and met the Blue Ridge Hot Shots. He looked back and saw that the point where he had been had already burned over. He then got in the Blue Ridge Hotshots’ vehicle and was taken to a safety zone.  Brendan was not injured and did not have to deploy his fire shelter.

“The wind changed,” said Prescott Fire Battalion Chief Ralph Lucas, explaining the movement of the fire. “We had a thunderstorm that was above. They have a tendency to push winds around, just because of the dynamics of nature, and that may have been what occurred during that time period, that brought fire up toward his trigger point, indicating that it was time for him to leave his lookout point.”

Mr. Ward implored the audience to protect Brendan’s privacy and to leave him alone, which precipitated applause from the crowd. Then he said, “Give him some time. And when I mean time, it’s going to take weeks, if not longer”.

Multiple firefighter fatalities on the Yarnell Fire in Arizona

(This article was updated numerous times over a couple of weeks, beginning June 30, 2017. To read it in chronological order, scroll to the bottom. The first entry was posted at 9:32 p.m. MDT, June 30, 2013)


(UPDATED at 2:26 p.m. MDT, July 15, 2013)

Most of the funerals are over for the 19 members of the Granite Mountain Hotshots that were killed on the Yarnell Hill Fire June 30. From information provided by the incident management team that organized the services, the firefighters are listed below.

19 Granite Mountain Hotshots

The incident management team has posted hundreds of photos of the memorial service, the procession, and the planning.


(UPDATED at 10:20 a.m. MDT, July 5, 2013)

An article in the LA Times has some previously unpublished information about the last moments of the Granite Mountain 19. Apparently the crew was attempting to establish an anchor point, presumably at what had previously been the heel, or rear of the fire. They were constructing fireline and may have been burning out that day. A photo that I had not seen before that was texted to the father of one of the firefighters father at 4:04 p.m. shows a firefighter in what appears to be a burned area, looking at the fire. The text said: “This thing is running straight for Yarnell”. By 4:47 p.m. the Arizona State Forestry Division received word sent up through channels that fire shelters had been deployed on the Yarnell Hill Fire.

Below is an excerpt from the article:

Team leader [Crew Superintendent] Eric Marsh told his commanders via radio that the group had a predetermined safety zone. “He was calm, cool and collected,” Ward said. “They all stayed together. Nobody ran.”

Moments later — Ward doesn’t know how long — Marsh radioed his superiors a second time. This message was different: He and his men were going to deploy the small emergency shelters that were their last resort against an advancing fire.

“From what I’ve heard, it was the calmest they’ve ever heard Eric,” Ward said. “They were in a tight spot and everyone knew this was going to be a bitch. But his voice was very calm: ‘We’re deploying.’ ”

Fire officials tried desperately to save the men.

Danny Parker, a fire battalion chief from the nearby Chino Valley Fire Department whose son Wade Parker died with the other Granite Mountain crew members, said he learned from colleagues that his son was in trouble.

“They had deployed their emergency shelters, and helicopter crews were trying desperately to spot them through dense smoke,” he said, wiping tears from his eyes.

He said he was told that Sikorsky helicopters were making water drops in areas where they thought the trapped firefighters might be.

“They weren’t sure about the men’s position because they couldn’t see through the smoke,” he said.

Their bodies were found in a single group, huddled together.


An Associated Press article provides some information about the autopsies of the firefighters:

Cari Gerchick, a spokeswoman for the Maricopa County Medical Examiner’s Office in Phoenix, said the Hotshots died from burns, carbon monoxide poisoning or oxygen deprivation, or a combination of the factors. The autopsies were performed Tuesday, but more detailed autopsy reports should be released in three months, pending lab work.


The Prescott Fire Department has brought in an Incident Management Team to help plan the events related to the deaths of the firefighters. They have established a web site that appears to be devoted to the scheduled events, as well as a Facebook page for photos and other information.

Their web site said that on Sunday, June 7 the remains of the 19 fallen fire fighters will be escorted with full Honor Guard from Phoenix to the Yavapai County Medical Examiner’s Office in Prescott. The procession will begin at 10 a.m. but the exact route is still being planned.

AZCentral has an article about a photo that has stirred some controversy. It shows flags draped over what appear to be body bags containing the 19 dead firefighters. They said the photo appeared on a Facebook page described on the site as “a community, news, and donation page (that) is not directly related to the Granite Mountain Hotshots personally.” AZCentral did not provide a link to the page or give its exact name but they do have a copy of the photo.


(UPDATED at 7 p.m. MDT, July 3, 2013)

(Information about the Yarnell Hill Fire itself is in our main article about the fire. This one is devoted to the 19 firefighters that died.)

The memorial service, not the funerals, for the Granite Mountain 19 will be held Tuesday, July 9 from 11 am to 1 pm at the Tim’s Toyota Center in Prescott Valley. There will be seating for 6,000 attendees with room for overflow outside.


According to the Professional Fire Fighters of Arizona, the 3 official fundraising efforts to help the families of the fallen have raised about $700,000.

  • The 100 Club has raised approximately $500,000.
  • The Wildland Firefighters Foundation (52 Club) has raised approximately $120,000.
  • The United Phoenix Fire Fighters and Prescott Firefighters Charities have raised approximately $80,000. They can receive donations through PayPal.

In the Prescott/Yarnell area, two local fundraising events have been scheduled for this week.

  • 4th of July Fireworks at Pioneer Park from 12 noon to 10 pm.
  • Whiskey Row Street Dance on Saturday, July 6th 5-11pm

Other fundraising events will be announced in the days to come.


Residents of Yarnell can obtain updates on the status of their property by calling the County Emergency Operations Center at 928-777-7481.


In the first 24 hours following the entrapment there were reports that up to six people had been injured and were being treated in hospitals, but there were no injuries, according to a spokesperson for the fire. There were 19 fatalities.


The crew carriers of the Granite Mountain Hotshots were removed from the fire where they had been parked by the crew, to Prescott today. Prescott Fire, Prescott Interagency Hotshot Crew, and Ironwood Hotshot Crew escorted the group from the Yarnell Hill Fire to the City of Prescott.


On Sunday, July 6, the Granite Mountain 19 will be escorted from the Medical Examiner’s Office in Phoenix to the Medical Examiner’s Office in Prescott. There will be 19 hearses, each with an honor guard member to accompany the fallen firefighter.


The last members of the nine person team that will be investigating the fatalities of the 19 firefighters on the Yarnell Hill fire arrived Tuesday and received an inbriefing in Phoenix from the Arizona State Forester. One of their main objectives will be to explore lessons learned and how to prevent a similar tragedy in the future.

Described as an “independent investigation” in a news release, it will be led by Florida State Forester Jim Karels. Mike Dudley, Acting Director of Cooperative Forestry for the USDA Forest Service, will be the secondary team lead. Other entities participating in the investigation include the U.S. Forest Service’s Missoula Technology and Development Center, the Missoula Fire Department, the Bureau of Land Management, and the Arizona Division of Occupational Safety and Health. Some of the team members are technical specialists and fire behavior analysts.

The local liaisons to the nine-member Yarnell Hill Investigation Team are Arizona State Forester Scott Hunt and Prescott Fire Chief Dan Fraijo.


Carrie Dennett, a Fire Information Officer with the Arizona State Forestry Division, said the Arizona Dispatch Center first received a call at 4:47 p.m. June 30, that firefighters on the Yarnell Hill Fire had deployed fire shelters. The Dispatch Center was not in direct communication with firefighters on the ground at the fire. The information would typically have been relayed from the local Yarnell Hill Fire organization up through lower level dispatch offices.

Another spokesperson for the fire said the fatalities occurred between where the fire was at the time and the town. That would put the firefighters N, NW, or E of the town — between an approaching thunderstorm and the town.

Arizona: Yarnell Hill Fire

(This article was updated numerous times over six days, beginning June 30, 2017. To read it in chronological order, scroll to the bottom. The first entry was posted at 6:15 p.m. MDT, June 30, 2013.)


(UPDATE at 9:35 a.m. MDT, June 5, 2013)

Firefighters are making good progress on the Yarnell Hill Fire. Two maps released yesterday show the exact perimeter in detail and where fireline had been constructed when the maps were made on July 3. Today the IMTeam is calling the fire 80 percent contained. One of the maps says it has burned 8,165 acres, which is a revision from the 8,400 figure that has been used for several days and is still shown on InciWeb.

Evacuation orders were lifted for residents of Peeples Valley at 6:30 p.m. on Thursday, July 4. Only residents with valid identification will be allowed access into the community.

Residents needing information regarding the status of their properties can contact the Yavapai County Sheriff’s Office at 928-427-6475.

We have more information about the deaths of the 19 firefighters and the weather that appeared to be a factor in the tragedy.


(UPDATE at 7:30 p.m. MDT, July 3, 2013)

State Highway 89 remains closed between Date Creek Road south of Yarnell to mile marker 283 north of Peeples Valley.

There are 596 personnel assigned to the fire, including eight crews, 44 engines, and 9 helicopters.

The MODIS satellite found no concentrations of heat when it overflew the fire at 12:25 p.m. Wednesday. It can detect heat sources larger than 30 meters across.

Wednesday evening the Incident Management Team said the fire is 45 percent contained. This is a jump from the 8 percent number they were using yesterday. (But, refer to our explanation below about containment percentages.) The number of acres has not changed for a couple of days, and remains at 8,400.

The IMTeam had not released a map of the fire since July 1, until they released the one above today. HERE is a link to a larger version of the map.

Map of Yarnell Fire, July 2, 2013
Map of Yarnell Hill Fire, July 2, 2013. The source of the perimeter data was a GPS device.

The Yarnell Hill Fire spread very little Tuesday and the Incident Management Team kept the reported acreage the same, at 8,400. The MODIS satellite detected no concentrations of heat larger than 30 meters across when it overflew the fire at 12:20 a.m. Wednesday. The IMTeam is estimating that 50 primary structures have burned, but this number may still be revised after assessments are complete. Approximately $1.75 million has been spent on the fire so far.

The Team selected 8 percent as the containment percentage they are distributing to the public. Until late yesterday they said there was no containment, meaning no fire line had been constructed and held. Until a few years ago, the containment percentage was an actual statistic, the amount of fire line completed and held compared to the fire line that still needed to be built, but recently it has become politicized and meaningless. There may still be some IMTeams that accurately report containment, and hopefully the IMTeam managing this fire is one of them. But since the public has no way of knowing, there is no point in getting excited about a containment percentage figure. More information about describing a fire as contained, controlled, or out is at the National Wildfire Coordinating Group’s web site.

Below is an excerpt from an update issued by the IMTeam Tuesday night at 10 p.m.:

Today, firefighters made good progress on the northeast corner and the fire perimeter near Yarnell. Two hot shot crews scouted the western flank until the threat of thunderstorms caused them to move to safer areas. Creeping and smoldering continued around the structures, primarily in the afternoon, and some areas around structures are still holding enough heat to be a concern. A plan is being developed to restore utilities and infrastructure to the affected communities. Contingency lines were scouted in case the fire becomes active again. Tonight, crews will be patrolling in the developed areas and working on flareups and visible heat.


(UPDATE at 3:02 p.m. MDT, July 2, 2013)

During the 11:27 a.m. overflight today, the MODIS satellite did not detect any large concentrations of heat larger than 30 meters square on the Yarnell Hill Fire, but there could still be a lot of work left for firefighters, including constructing fireline. With so much uncompleted line, there is still the possibility for the fire to continue to spread.

The Yarnell Hill Fire was less active Monday than it was on Sunday when it rapidly overran the position of the Granite Mountain Hotshots, killing 19. (More information about the fatalities.)

Air tankers and firefighters worked the north perimeter of the fire where it continued to spread, and 5 helicopters assigned to the fire dropped water on hot spots in support of the firefighters. Efforts continued to secure the east flank to protect other homes at risk.

The Incident Management Team reported that 50 primary structures have burned in the fire. As of 9:30 p.m. on Monday they said it had blackened about 8,400 acres, was zero percent contained, and was being fought by about 500 personnel.

Clay Templin’s Type 1 Incident Management Team assumed command of the fire at 6 p.m. Monday.

Fire officials will hold Community Meetings on July 2: 11 a.m. at Wickenburg High School and 3:30 p.m. at the Prescott High School.


(UPDATE at 7:30 p.m. MDT, July 1, 2013)

The Incident Management Team reports that an estimated 200 homes and other structures burned Sunday in Yarnell. The Yarnell Fire Department will continue to assess the damage Monday.

The New York City Fire Department is sending five members of their Incident Management Team to assist in managing the Yarnell Fire.
