A former hotshot superintendent is suing the Department of Agriculture to get information the U.S. Forest Service so far has not released about the Yarnell Hill Fire. On June 30, 2013, 19 members of the Granite Mountain Hotshot Crew were entrapped and killed on the fire near Yarnell, Arizona.
Fred Schoeffler is seeking recordings or transcripts of radio transmissions with aircraft that were working on the fire.
Below is an excerpt from an article in the Republic:
Schoeffler, a former hotshot supervisor in Payson for 26 years, alleges that the Forest Service answered his Freedom of Information Act request by claiming they “did not find any responsive records.” Wildfire officials previously have acknowledged the study was underway, and Schoeffler’s complaint notes that air-to-ground voices of those taking part are audible in Forest Service videos released after the fire.
Thanks and a tip of the hat go out to Jeff and Dick.
The firefighters were part of the Navajo Interagency Hotshot Crew (NIHC) that remained along with two Type 6 engines and possibly one other crew after the Type 1 Incident Management Team was released the previous day. The assignment of half the crew, nine firefighters, was to “monitor” a part of the southwest side of the fire that had six miles of uncontained fire edge. The other half was working on the southeast side.
Three of the nine personnel on the southwest side served as lookouts while the remaining six were monitoring and checking the fire edge. When a very large fire whirl developed near the six, they realized their escape route was cut off, and took refuge in a previously burned area. The ground fuels had burned, but the canopy was still intact. As the fire approached they deployed their fire shelters, remaining in them for about 30 minutes.
After the fire whirl subsided, the squad members were able to hike out to staged vehicles. They were transported in three ambulances, medically evaluated, and transported to Summit Hospital in Show Low, Arizona where they were evaluated. Two firefighters were treated for smoke inhalation and all were released by 10 p.m. that evening.
The report says the personnel deployed and entered the shelters just as they had practiced several times in training, and the devices worked as designed. There were no difficulties, as reported at other entrapments, with the PVC bags becoming soft and difficult to open.
Thankfully there were no serious injuries and the training the firefighters had received paid off.
But there are a number of interesting facts about what occurred before the entrapment
Resources on the fire
On June 27, the day before the entrapment, the Type 1 Incident Management Team issued their final update on the 45,977-acre fire just before they were released later that day. Below is a portion of the document.
The report claims the Type 1 Team recommended that the number of personnel assigned be reduced on Tuesday June 28 to about 400. But on Monday, June 27 all firefighters except for two Type 6 engines were released. With a 70 percent chance of rain in the weather forecast, on Tuesday the local agency decided to replace the Type 1 Team with a Type 4 Incident Commander, two Type 6 engines, and one or two hand crews. The crew(s) had to be re-mobilized on Tuesday after being released. Some aircraft were also assigned on Tuesday.

Weather on Tuesday, the day of entrapment
About 20 minutes before the 2:45 p.m. entrapment the weather at the fire was 95 degrees, 21 percent relative humidity, with a 7 to 10 mph wind out of the south. Although “numerous” people observed dust devils and fire whirls before the large fire whirl formed, there was no discussion about modifying fire suppression tactics. Dust devils can be an indicator of the potential for extreme fire behavior.

From the Insurance Journal:
Attorneys for Yarnell residents who lost their homes in the deadly 2013 Arizona wildfire are asking the Court of Appeals to allow their clients to sue the state.
KJZZ-FM reported that previously homeowners sued the state Forestry Division, but a trial judge dismissed the case concluding the state had no duty to protect the residents’ property.
At a hearing [September 21, 2016] an attorney for the state said Arizona is not responsible for protecting everyone who chooses to live adjacent to wilderness.
Plaintiffs’ attorney David Abney says that since the state fought the fire, it voluntarily agreed to try to protect Yarnell. Abney wants the appellate court to give his clients a chance to make their case to a jury.
The 2013 Yarnell wildfire killed 19 firefighters and burned more than 120 homes.
To our knowledge, the Court of Appeals has not yet handed down their decision.
We looked further into what led to the smoky conditions that resulted in numerous vehicle crashes on Interstate 40 west of Flagstaff, Arizona early Wednesday morning, October 19. The smoke on the highway from a prescribed fire was referred to as “pea soup”, and was clearly the cause of some of the accidents, but investigators are not yet ready to say the smoke caused the one fatality when a vehicle was sandwiched between two semi trucks.
During the very early morning hours of Wednesday, October 19, smoke settled into the areas around Interstate 40 between Parks and Williams. An electronic sign warned motorists about smoke, but the severely reduced visibility was not anticipated by the U.S. Forest Service. After the accidents started occurring the Interstate was closed for five hours.
The Kaibab National Forest ignited the Green Base Prescribed Fire on Tuesday, October 18, 2016 immediately north of Interstate 40. The smoke permit issued by the Arizona Department of Environmental Quality anticipated moderate “impacts on sensitive areas”:
Smoke impacts to the following communities of Flagstaff, Parks, Spring Valley, Pittman Valley, Sherwood Forest Estates and some smoke may impact Williams. I-40 may experience moderate smoke impacts in low-lying areas.
The Flagstaff office of the National Weather Service issued a Spot Weather Forecast for the Green Base Prescribed Fire at 5:28 a.m. MST on Tuesday October 18, 2016. It anticipated a “good” maximum ventilation rate for Tuesday, did not specify one for Tuesday night, and for Wednesday it was described as “fair”.
The ventilation rate provides an estimate of how high and how far smoke will disperse. A high ventilation rate suggests that smoke will spread out quickly and through a deep layer of the atmosphere, so that surface concentrations downwind will be lower than they would be with a lower ventilation rate.
The transport winds (from the ground to the mixing height) for Tuesday night were predicted to be “west 5 to 10 knots shifting to the north after midnight, then shifting to the northeast early in the morning.” The wind speed after the shift was not specified. Perhaps this was interpreted by fire managers to mean it would continue at 5 to 10 knots.
The prescribed fire was just north of the east-west Interstate, so a wind out of the northeast would likely push the smoke toward the highway. And if an area is prone to nighttime inversions, visibility can be compromised.
Fox News reported that Cory Mottice, a National Weather Service meteorologist in Flagstaff, said, “[Smoke] always gets trapped after dark,” he said. “It’s just a question of where the wind blows it.”
However that analysis was not described in detail in the spot weather forecast issued by Mr. Mottice’s office. As in many spot weather forecasts, much of the information appears to be generated by a computer, with little interpretation or discussion about how the information will affect the fire. Meteorologists are not expected to be Fire Behavior Analysts, but sometimes a little human-created discussion and interpretation can add value to a computer product.
Below are excerpts from an article at the Arizona Daily Sun:
… A Highway Patrol captain at the scene said smoke in the area reduced visibility down to about 20 feet, Department of Public Safety spokesman Bart Graves said. Sherwood Forest Estates Fire Chief Wayne Marx said even his crews had to stick their heads out the window to watch the yellow stripe on the road as they escorted commuters away from the interstate.
“You couldn’t see past the end of the hood,” Marx said.
One retired meteorologist who lives in the area believes more precautions should have been taken. Parks resident Byron Peterson, who retired from National Weather Service station in Bellemont, said the smoke was already bad on Old Route 66 Tuesday afternoon. Firefighters waved him on, he said, even though there were times when he could not see 10 feet in front of him.
“It was very frightening to say the least,” Peterson said.
He said strong southwest winds coming up over Bill Williams Mountain near Williams formed an eddy of swirling air that then dove down over the prescribed burn, keeping the smoke from dissipating.
“I tried to explain that to people at the Forest Service and it was just like talking to a wall,” he said.
After numerous accidents occurred in thick smoke from a prescribed fire, authorities closed Interstate 40 west of Flagstaff, Arizona on Wednesday. The Kaibab National Forest conducted the burn Tuesday and knew that a wind shift would push the smoke toward the interstate, but they were surprised that the smoke settled near the ground early Wednesday morning rather than being moved out of the area. Electronic signs warned drivers about the potential hazard.
Below is an excerpt from Fox News:
Multiple collisions with minor injuries to motorists and passengers were blamed on smoky haze that settled over the highway for about five hours. Authorities closed I-40 for hours to prevent more accidents.
Police had not immediately determined whether the poor visibility was the cause of a fatal accident after a vehicle was sandwiched between two tractor-trailers before dawn, said Arizona Department of Public safety spokesman Bart Graves.
But the area at this time of year experiences temperature inversions allowing smoke to be trapped close to the ground and hover over the highway, said Cory Mottice, a National Weather Service meteorologist in Flagstaff.
“It almost always gets trapped after dark,” he said. “It’s just a question of where the wind blows it.”
Forest officials thought weather conditions would vent smoke near the freeway more than it did in low-lying areas, Smith said.
“I believed they used good judgment based on the conditions and the information that they had,” said Brady Smith, a U.S. Forest Service spokesperson.
Rainfall over the last two weeks has slowed or in some cases, ended the wildfire season in some areas.
On October 19 we ran the numbers for the accumulated precipitation for the last 14 days in the western states. These maps show amounts that exceeded 0.05 inches at some of the Interagency Remote Automatic Weather Stations (RAWS).
Washington, Oregon, and northern California have received a good soaking and I would imagine that local fire officials may be declaring an end to the fire season. Of course this is not unusual for these areas this time of the year, and some locations had already seen their season end. But what IS unusual, is the high amount of moisture that occurred in just two weeks.
