Forest Service has 18 large air tankers this year under contract

The schedule calls for most of them to begin in April and May

large air tanker Requests filled, UTF, and Canceled

The U.S. Forest Service has 18 large air tankers on exclusive use (EU) contracts this year.

In 2020 the agency started out with 13 on contract in April and May but by June 24 had added 11 on modified call when needed (CWN) contracts for a total of 24. Modular Airborne FireFighting Systems C-130 aircraft from the National Guard and Air Force Reserve were deployed from July 23 until October 4 in 2020, usually two at a time.

Requests for USFS LATs UTF or Canceled

This year the 18 EU large air tankers are being supplied by five vendors:

  • Six, Aero Flite (RJ85)
  • Four, Erickson Aero Tanker (MD87)
  • Four, Neptune Aviation (BAe-146)
  • Two, Coulson Aviation (C-130)
  • Two, 10 Tanker (DC-10)

The dates they will first be on duty could change if the Forest Service decides they need to come on early, but the scheduled 160-day “mandatory availability periods” (MAP) which are different for every air tanker specify that two will begin in March (11th and 17th) and most of the rest will start in April and May. The MAPs end August 18 through November 20 for the 18 aircraft, but those dates could be extended if necessary.

The 2020 fire season started with much less activity than average (see the chart below) but when hundreds of fires began burning millions of acres in the West in mid-August, the number of large air tankers on contract was less than was actually needed. September 19 saw 32,727 fire personnel deployed, the highest number since August 24, 2015 when 32,300 were assigned. Many fires during that six-week period had numerous requests for ground and aviation firefighting resources that were unable to be filled when the fires were discovered. This allowed some of the blazes to grow virtually unchecked for days — or longer. In 2020, 34.3 percent of the requests for large air tankers were either cancelled or unable to be filled.

Since 2001 the four years with the highest number of total fire detections in Washington, Oregon, and California have all occurred since 2015, according to satellite data processed by the New York Times in September of last year.

Firefighters in New Jersey are taking advantage of good weather to conduct prescribed burns

The New Jersey Forest Fire Service hopes to treat 30,000 acres this year

Due to much of the state being covered in snow during the month of February and with a goal of completing prescribed burns by March 15 looming, New Jersey Forest Fire Service crews are working hard to make up for lost time. Their crews started burning last week during the first good weather window of 2021, with a 9,000-acre goal for the weekend. The agency considers the prescribed burning program to be one of its primary tools to reduce hazardous fuels that that can increase the intensity of wildfires.

These photos were taken March 6 by James Douglass at a 2,300-acre prescribed burn at the Warren Grove Gunnery Range in the heart of the Pine Barrens of New Jersey.

This year the NJFFS anticipates conducting prescribed burns on at least 30,000 acres depending on weather conditions. Most burns occur on state-owned property such as state forests, parks, wildlife management areas, and other government lands. The Forest Fire Service also assists private landowners and nonprofit organizations to meet their management objectives through prescribed burning.

In 2020, the Forest Fire Service completed burns on 18,854 acres of state-owned lands, 5,006 acres of other government-owned land, and 2,268 acres of privately owned property, for a total of 26,128 acres.

Agate Bed Fire burns 2,000+ acres in Western South Dakota

The blaze was driven by winds gusting above 30 mph

Firefighters from multiple counties stopped a fire east of the Black Hills in South Dakota Saturday after it had burned 2,000 to 3,000 acres during Red Flag Warning conditions.

The fire was approximately 9 miles east of Fairburn on the Buffalo Gap National Grassland.

“The majority of fire was in a wilderness study area, which complicated suppression efforts,” said Jim Strain, Assistant Chief of the Fairburn Volunteer Fire Department.

Saturday afternoon the wind was blasting, with sustained speeds of 15 to 25 mph with gusts above 30 mph while the relative humidity was in the high teens and the temperature in the high 60s — difficult conditions for firefighters. After dark the wind slowed, 5 to 10 mph but with occasional gusts of 15 to 25 mph. Sunday afternoon it increased to 15 mph and 25 mph gusts, along with 27 percent relative humidity.

Black Hills National Forest conducts 380-acre prescribed fire

Red Flag Warning in effect for the area Saturday

The Black Hills National Forest conducted a 380-acre prescribed fire Wednesday through Friday of this week approximately 5 miles southwest of Rapid City, SD.

Today, Saturday March 6, a Red Flag Warning is in effect for the area.

“Warm temperatures and dry fuels, combined with very low humidity and gusty south to southwest winds, will result in extreme fire danger across the area,” the National Weather Service said in an advisory Saturday.

The forecast for Saturday predicts 17 to 24 mph winds out of the southeast and a minimum relative humidity of 11 percent. The strong winds are expected to continue Saturday night shifting to come from the west and then the northwest, with the RH ranging from 24 to 48 percent.

Specially treated wire mesh could protect power poles from wildfire

Originally published at 5:49 p.m. MDT March 4, 2021

Wire mesh treated with an intumescent graphite coating may be able to prevent a wooden power pole from being consumed in a wildfire. It could also be effective on a railroad bridge or under the eaves of a house.

When subjected to heat, an intumescent rapidly expands and can fill in the gaps in the wire mesh to form a barrier between the fire and the wood. Before the fire, the mesh allows air flow, preventing a buildup of moisture that could lead to wood damage.

I first learned about the product when seeing a report that NVEnergy installed it last month on 170 power poles as a pilot program in Nevada, looking at it as a way to protect equipment in the event of a wildland fire. The company installed it at either a 6 or 20-foot height, depending on the surrounding vegetation.

In September, 2019 we wrote about a fire resistant paint that was applied by the Idaho National Laboratory on 3,000 power poles. They prioritized poles receiving the paint based on service area, fire risk, and vegetation density. Every pole painted in the latex-based fire retardant paint survived the 2019 Sheep Fire. Even poles that had not been repainted since their initial coat in 2012 and 2013 survived.

A big thank you to Robert Tissell who pointed out in a comment on this article that the TV show “This Old House” showed vents being installed in a home in Paradise, California that use the same process. Vulcan Vents says they are  “manufactured out of high grade aluminum honeycomb and coated with an intumescent coating made by Firefree Coatings. The intumescent coating is designed to quickly swell up and close off when exposed to high heat. The expanded material also acts as an insulator to heat, fire and embers.”
