With 35 large uncontained wildfires currently burning in the United States, and many, many more in various categories, we can’t report extensively on all of them, so today we will take a slice of geography and look briefly at seven fires spreading in the Central Idaho area, and extend it just a bit into Oregon and Montana.

Moose (Idaho)
The largest of these seven fires is the Moose, which has been chewing through eastern Idaho since July 17. As far as the cause, the Salmon National Forest says, after almost two months, it is “human caused,” which only eliminates the causes of volcano and lightning. Nine structures have been destroyed. On Friday 650 personnel are assigned to the 125,000-acre blaze which is 5 miles northwest of Salmon, ID. A satellite overflight Friday afternoon only found large heat sources in the southeast portion and that is where an additional 15,000 acres burned Wednesday night, prompting evacuations near Salmon.

Crews reengaged the fire and began preparing new contingency lines along the west edge of the city. Several water pumps, five log decks, and some portable water storage tanks (nicknamed pumpkins because of their shape and color) were destroyed Wednesday.  No firefighters were injured. Nearly 500 acres of the city’s Municipal Watershed burned that night, something the various incident management teams had been trying to protect since July.

Cooler temperatures, higher relative humidity, and thick smoke contributed to minimal fire behavior across the fire Thursday.

Indian Ridge (Idaho)
Northwest of the Moose Fire near the Montana border is the lightning-caused 8,670-acre Indian Ridge Fire on the Bitterroot National Forest. It is in the Selway-Bitterroot Wilderness 30 miles southwest of Darby, Montana. The fire has been active this week primarily along the western and northern flanks and north of Indian Creek as it burns through steep, rugged, remote terrain with heavy surface fuels and dead standing timber.

The fire is not being fully suppressed. Their daily reporting says, “Fire managers are utilizing a point protection strategy to prevent any critical wilderness infrastructure from being negatively impacted by the fire.”

Dismal and Patrol Point
These two fires are very close to merging after significant growth since September 6, and combined have burned an estimated 23,000 acres. They are about 50 miles northwest of Salmon, Idaho. Smoke and the unavailability of infrared mapping aircraft have made it difficult to determine the current perimeters, but there is a lot of new burned acreage between the two fires. Recent low humidity and strong winds are in part responsible for the recent growth.

Areas that fire managers intend to protect include Cold Meadows Guard Station, Root Ranch, and Lantz Bar.

Williams Creek
The 11,881-acre fire is 5 miles west of Orogrande, near Wildhorse Lake, 7 miles southwest of Elk City, and 8 miles north-northwest of Dixie.

“Resources will continue to engage the fire in Orogrande and the Crooked River corridor, addressing and extinguishing hot spots and conducting damage assessments,” said a September 9 update from the Incident Management Team. “The fire and associated winds did impact structures and outbuildings; crews are still assessing the extent of the damage. Fallen trees, burned snags, and downed power lines continue to present safety hazards.”

Double Creek (Oregon)
The 137,000-acre lightning-caused Double Creek Fire is in Oregon just west of the Idaho border. It has burned to the Snake River in the Pittsburg Landing area. A River Group has been established to assess and protect structures along the waterway. The fire is being fully suppressed and crews are looking for locations to establish the control line farther from Lower Imnaha Road where topography allows. Two structures have been destroyed.

Trail Ridge (Montana)

The 13,000-acre Trail Ridge fire is on the Beaverhead-Deerlodge National Forest in Western Montana about 5 miles east of the Idaho Border and 4 miles southeast of Sula, MT. The cooler weather experienced Thursday and Friday was helpful in slowing the spread of the fire and decreasing the severity of fire behavior. It is burning above 7,000 feet elevation near the Continental Divide and there is no current or expected threat to private land and property. It is not being fully suppressed.

Military activates two MAFFS air tankers to join fire fight

The National Interagency Fire Center (NIFC) has requested two Department of Defense C-130 aircraft equipped with Modular Airborne Fire Fighting Systems (MAFFS) to support wildland firefighting operations in support of NIFC in the northwestern United States. One C-130H from the Nevada Air National Guard’s 152nd Airlift Wing, Reno, Nev., and one C-130J from the California Air National Guard’s 146th Airlift Wing, Port Hueneme, Calif., will arrive at Boise Airport in Idaho today. The aircraft are standing by for flying on behalf of a DoD-approved US Forest Service Request.

“We greatly appreciate the assistance of our military partners,” said Kim Christensen, deputy assistant director for operations for the US Forest Service. “These aircraft will help provide additional capacity for aerial firefighting.”

Having military C-130s that can be converted into air tankers provides a critical “surge” capability that can be used to bolster wildfire suppression efforts when commercial air tankers are stretched thin or an inadequate number remain available for initial attack.

Nationally there are 35 large uncontained wildfires being managed by 26 Type 1 or 2 incident management teams. As of Friday morning 156 helicopters are committed to fires along with more than 17,000 personnel. The number of contracted large air tankers activated was 23, plus 6 water scooping air tankers, before the 2 MAFFS came on board.

Firefighters working to save structures in the Mosquito Fire in Northern California

It has burned tens of thousands of acres near the community of Foresthill

Mosquito Fire map 11:45 p.m. PDT Sept. 9, 2022. The white line was the perimeter about 24 hours before. The orange areas represent intense heat.

The Mosquito Fire at Foresthill in Northern California was very active again Friday, but did not spread as much as in recent days. That was due to the overnight and morning inversion layer dissipating later than usual and very little wind, ranging from calm to three mph Friday and Friday night. The temperature was 93 degrees and the minimum relative humidity was 21 percent.

The forecast for Saturday is 88 degrees, afternoon winds out of the southwest at 8 mph, 50 percent cloud cover, and 27 percent relative humidity. Sunday should be about the same.

Despite the moderate weather conditions, on Friday there was incremental growth on most of the perimeter except for along Foresthill Road and the area 1 to 5 miles east of Volcanoville. At its widest point the fire is 12 miles long.

The fire was mapped Friday night at 33,753 acres.

The Incident Management Team plans to provide structure defense and point protection for values at risk and protect private timberlands.

The map below shows fires in the National Interagency Fire Center database that have occurred in the area since 1990. It appears possible that under extreme weather and fuel conditions the fire could spread significantly to the east or northeast. The Mosquito Fire about 6 miles from the 2014 King Fire and 28 miles from Lake Tahoe.

Firefighters have been working hard to save structures in the Foresthill area as the Mosquito Fire grows larger. Early unofficial reports say they were successful.

Most of the movement is to the east and southeast, but it has also been spreading west into the community of Foresthill and has moved into El Dorado County. It was mapped at about 11 a.m. Friday at 29,585 acres.  Friday morning the area is thick with heavy smoke, preventing tactical aircraft from flying.

Cameras were able to provide images of the fire into Thursday night until smoke obscured the view.

Fire officials are aware of damage to structures in the Michigan Bluff area, and possibly other locations, and will survey the effects when it can be done safely.

The status of evacuations has changed. Placer County has a map showing evacuation orders and warnings. El Dorado County also has a map.

The blaze exhibited extreme fire behavior Thursday, forming huge rotating convection columns.

Spread of the Radford Fire at Big Bear slows in Southern California

Rain is expected to begin Friday afternoon

9:45 a.m. PDT September 8, 2022

The spread of the Radford Fire just south of Big Bear in Southern California slowed Wednesday night and Thursday morning as the wind slowed to a calm in some areas and the relative humidity rose to 50 to 70 percent depending on the location on the mountain. With the change in the weather, Thursday morning the fire is burning in the understory with only limited torching or uphill runs.

That could change Thursday afternoon as the influence of Hurricane Kay increasingly affects the area. The wind is expected to increase to 14 mph out of the southwest gusting to 22 while the relative humidity drops into the 30s. Winds should be much more subdued overnight but on Friday will increase by 4 p.m. to 25 mph gusting out of the east-southeast up to 39 mph with RH in the 30s and 40s. Beginning at 11 a.m. on Friday the chance of rain jumps to 60 percent with the RH rising to 80 percent. Precipitation amounts through Friday night could be more than 0.6″ of an inch. The rain could continue into Saturday night or Sunday morning.

The Fairview Fire southeast of Hemet, California was extremely active Wednesday night, exhibiting extreme fire behavior resulting in fire officials requesting an additional 25 engines. It pushed strongly to the south and to the east as it doubled in size in about six hours, growing to 19,377 acres. (see map above)

Evacuation areas have been expanded. More information.

When the fire was mapped Wednesday at 10:23 p.m. it had spread south across Red Mountain Road, Oak Glen Road, and Timber Trail. At that time it was about three miles northeast of the community of Sage and was still east of Sage Road.

Fairview Fire
The Fairview Fire was very active September 8 at 3:41 a.m., as seen looking WSW from the Idyllwild camera.

The east side continued growing east across Bautista Road and when last mapped had reached Forest Road 5S15 about a mile from Highway 74.

Three large helicopters from the Quick Reaction Force worked the fire during the night, dropping retardant aided by their intelligence gathering helicopter.

The spot weather forecast issued Wednesday at 5:27 p.m. predicts for the fire area on Thursday 94 to 100 degrees, 21 percent relative humidity, and winds out of the west at 4 mph. There is a small chance for wetting rains Friday afternoon which will increase to about 40 percent by late Saturday morning.
