Four large wildfires in the Reno/Sparks, Nevada area have burned a total of about 115,000 acres since the first ones started July 3.  Brook Chadwick’s Type 2 incident management team will be assuming command of the Earthstone, Truckee, and Winnemucca Ranch Fires.

Earthstone Fire, 26,785 acres, just northeast of Reno/Sparks.

Information from Inciweb current as of about 8 p.m. MDT July 5, 2017:

“The Sierra Front Type 3 Incident Management Team assumed control of operations [presumably on Wednesday] and brought in additional resources, including two fire engine strike teams, to allow the releasing of some local fire crews to return to their home districts. A Type 2 Incident Management Team remains scheduled to assume command of the incident on Thursday morning.

Three additional fixed wing aircraft, including one Very Large Air Tanker (VLAT), made retardant drops today. Two Super Scooper air craft, requested from Alaska, are still on order and may arrive as early as Friday, bringing the total number of aircraft on the incident to 18.

Currently, there is no immediate threat to structures; however, residents of the Wadsworth area are encouraged to remain vigilant for the possibility of evacuation and complete their preparations as the head of the fire is now about 10 miles west of the town. Impacts to I-80 are expected in the vicinity of the USA Parkway within the next 24 hours.”

Truckee Fire, 70,546 acres, 28 miles northeast of Reno. Not much information is available, but it is exhibiting extreme fire behavior as it burns in brush and short grass in above normal temperatures and single-digit humidities.

Winnemucca Ranch Fire, 3,000 acres 8 miles north-northeast of Reno. Five structures have been destroyed on this fire and another 175 are threatened. Numerous animals and livestock have been evacuated along rural roads. The fire managers identified competition for firefighting resources as a problem.

Limerick Fire, 14,656 acres 94 miles northeast of Reno and 15 miles northeast of Lovelock. Two outbuildings have burned.

Information from Inciweb current as of about 9:40 a.m. MDT July 6, 2017:

“Firefighters stayed on the fire last night and were able to hold the fire line at the ridge to the south of Wright’s Canyon. Snow is still in the higher elevations and greener grass has helped keep the fire on the ridgetop.

Potential fire weather is predicted for the weekend and a structure protection group has been established as a contingency for active fire behavior.

Crews completed burn outs in the southeast corner of the fire yesterday and were able to connect containment lines to the dozer line near Golden Gate Hill. Crews will continue to secure fire line and begin mop up in the area near Couer Rochester Mine. Fire crews will continue to put in containment line on the eastern side of the fire working their way north.

Limerick Road is open to firefighter and mine traffic only.”

Videos of the first 5 hours of the Fairview Fire in Nevada

Above: Screen grab from the NVSeismoLab video.

The cameras operated by the Nevada Seismological Laboratory detected and recorded the ignition and spread of a wildfire near Fairview Peak south of U.S. 50 between Fallon and Austin in western Nevada. Below we have the time-lapse videos, each compressing about one hour to one minute.

According to KOLOTV the Fairview Fire burned at least 50 acres of Fallon Naval Air Station land.

Below the descriptions (provided by nvseismolab) are the applicable videos.


Although the fire starts at 12:50 PM, it begins in earnest around 1 PM … First fire discovery for 2017! Starting to pick up speed by hour’s end.

Although early in the season, the fire still manages to expand and move uphill in plain sight of the Fairview Fire Camera. Time lapse covers from 2 PM to 3 PM.

“Vegetation” involved in fire on roof of Las Vegas hotel

A fire on the roof of the Bellagio Hotel in Las Vegas created quite a show for people who came to watch the fancy water fountain display Thursday night. The Las Vegas Review-Journal wrote that styrofoam facades burned, but it appears that real or fake vegetation on the roof may have also been involved.

Firefighters were able to knock down the wind-driven fire about 25 minutes after it was first reported.

At least there was a wet line on one flank of the fire:

This reminds us of a similar fire on another hotel roof in Vegas in 2015. Here is a screenshot of part of that article:

Two reports released on the same day about the escaped prescribed fire near Carson City, NV

Above: Map of the Little Valley Fire at 9:23 p.m. PDT October 14, 2016.

On February 15 two reports were released about the prescribed fire that escaped, burned 2,291 acres, and destroyed 23 homes northwest of Carson City, Nevada on October 14, 2016. The first report about what became the Little Valley Fire included the results of a months-long independent investigation by the Reno Gazette-Journal (RGJ). The other, released a few hours later, was the product of the official investigation requested by the Nevada Division of Forestry (NDF), the agency responsible for conducting the prescribed fire.

Hours before the fire escaped, all eleven firefighters that had been mopping up the prescribed fire left the project and returned to their stations between 1:30 p.m. and 4:45 p.m. on October 13, 2016. During that day there were a number of smokes that received the attention of the firefighters. During the last two hours before the seven-person helitack crew departed they noticed the wind increasing — trees were blowing down and branches were falling.

The RGJ reported on the reason the firefighters were ordered to leave the burn site.

Gene Phillips, NDF forest health specialist and burn boss for the Little Valley Burn, made the decision to pull crews from the burn site after discussing the high wind forecasts for the evening with a burn boss trainee, according to the review.

The decision not to staff the site on the evening of Oct. 13 was made, according to NDF, “based on the limited amount of heat near the control lines, success of the current mop-up effort, and the risk to firefighters working in timber during high winds.”

From the NIMO report.

At 5:38 p.m. the Little Valley weather station recorded sustained winds out of the west at 15 mph with a maximum gust of 39 mph. By 12:38 a.m. on October 14, about the time the fire escaped, the wind was at 19 mph with gusts up to 87 mph. The relative humidity was 32 percent.

A Red Flag Warning for gusty winds and low humidity was in effect from the morning of October 11 through 5 p.m. on October 14. Strong winds persisted until mid-day on October 17.

The NDF’s report was written by the U.S. Forest Service’s Phoenix National Incident Management Organization (NIMO), a team that usually manages fires and other incidents that are often of longer duration than a typical wildfire. The team was supplemented with a Fire Behavior Analyst, a GIS/Fire Behavior Analyst, a Public Information Officer, a Fire Investigator, and others for a total of 10 personnel that were listed in the report.

The NIMO team concluded that the fire escaped when embers from a burning stump hole were blown 34 feet and crossed the fireline at a corner, or “dog leg” in the fire perimeter.

According to the RGJ there was confusion in initially responding to the fire after it escaped at around 12:38 a.m. on October 14:

Response to the fire was delayed, affecting how fast it could be contained: A call at 1:23 a.m. about smoke at the burn site was later dismissed as “unfounded,” causing a TMFPD [Truckee Meadows Fire Protection District] fire engine to return to the station three minutes after it left. After a second call about smoke at the burn site, it took TMFPD more than an hour to get to the site after crews were dispatched, according to 911 transcripts.

Rainfall in western states slows wildfire season in many areas

Rainfall last 2 weeks washington oregon
Rainfall last 2 weeks, Washington and Oregon

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.
