According to the National Interagency Coordination Center, today there are 50 large uncontained wildfires in the United States that are being aggressively suppressed. In addition, there are another 35 fires that are not being fully suppressed.

Very large numbers of firefighting resources are currently assigned across the United States, including 560 hand crews, 1,865 engines, and 222 helicopters, for a total of 27,256 personnel.

As of yesterday 7.9 million acres has burned this year nationally, which compares to the 10-year average of 5.4 million acres for this date.

Update on Chetco Bar Fire and other wildfires in the Northwest

The Chetco Bar Fire in Southwest Oregon has not been growing as quickly in recent days as it did earlier when it quadrupled in size over four days and crossed the 100,000-acre threshold. The most recent mapping puts it at almost 108,000 acres. The area is under a Red Flag Warning on through Tuesday for gusty southwest winds and low humidities which could result in increased burning intensity and rapid fire growth.

The 4,400-acre Jolly Mountain Fire in Central Washington is near a Red Flag Warning area. Fire officials’ expectations for Monday:

Southern and western flanks of the fire will become active with uphill crown runs both on the east and west sides of West Fork drainage. SE flank will continue to back downslope. Fire will become increasingly active as it spreads to the south, where it loses its downslope effect and in more exposed to general winds. Fire likely to cross Sasse Ridge to the west.

The 12,800-acre Liberty Fire has been burning northeast of Missoula, Montana since July 15 while the Rice Ridge Fire, not far away, has spread over 27,800 acres since it started two weeks later. Hot, dry weather on Monday could cause both blazes to become more active.

The wildfires in Southwest Oregon and Northwest California continue to grow at a fairly steady pace, with occasional large expansions during wind events.

The Chetco Bar Fire five miles northeast of Brookings, Oregon was mapped very early Thursday morning at 102,333 acres, moving past the 100,000-acre threshold into “megafire” territory. But it is still one-fifth the size of the Biscuit Fire that covered almost half a million acres in the same general area in 2002.

The red line was the perimeter of the Chetco Bar Fire at 12:16 a.m. PDT August 24, 2017. The white line was the perimeter two days before.

The map of the Chetco Bar Fire shows that while it continues to spread along much of the perimeter that growth has slowed since it quadrupled in size over a four-day period, August 18 to 22. It added 2,389 acres on Wednesday through minimal flanking, backing, and creeping fire behavior due to cooler temperatures and higher humidities.

More fighters have poured in to the Brookings, Oregon area which is five miles southwest of the fire. Over 1,100 personnel are now working on the blaze, including 21 hand crews, 118 engines, and 8 helicopters. The incident management teams report that 25 structures have burned.

Three teams are assigned to the Chetco Bar Fire: Livingston’s Type 1 team, Greer’s Type 2 team, and Houseman’s National Incident Management Organization (NIMO) team. (The NIMO folks need to come up with a better name for their teams.)

The fires in Northwest California do not receive much press coverage since they are in remote, sparsely populated areas. The largest is the Eclipse Complex of five fires 10 miles north of Happy Camp which has burned 40,500 acres. It is also known as “CA-KNF-006098 Complex”. On Wednesday the inversion that had been moderating fire behavior lifted over one of the five fires, the Prescott Fire, which became active and burned towards the Oak Fire. This produced a large smoke column that caused ash fall along the Hwy 96 corridor and throughout the Happy Camp area.

Chetco Bar Fire in Oregon quadruples in four days, approaches 100,000 acres

On July 13, 2002 the Biscuit Fire started in southwest Oregon. Under a limited suppression strategy 7,000 workers fought the fire as it spread into California. By November it had burned up nearly 500,000 acres and $150 million, becoming one of the largest wildfires in the recent history of the 48 contiguous states.

This summer another very large wildfire, the Chetco Bar Fire, is burning partially in the footprints of the Biscuit and another nearby blaze, the 1987 Silver Fire. Also under a limited suppression strategy, the 788 personnel assigned today are faced with the steep slopes in the Kalmiopsis Wilderness as well as brush and dangerous snags left in the previously burned areas.

Evacuations are in effect and Curry County Sheriff’s Office says at least five homes have been destroyed by the fire.

The Phoenix National Incident Management Organization (NIMO) Team with Incident Commander Bob Houseman, on the fire since July 29, explains their task:

Because of the risk to firefighter safety, low probability of success of a direct attack strategy and minimal values at risk, fire personnel are currently focused on constructing contingency lines, conducting reconnaissance for access, scouting safe entry points, locating natural features for containment opportunities, protecting wilderness values and developing a long term plan for safely engaging the fire.

On August 18 at 4 p.m. the Chetco Bar Fire covered 22,042 acres. Early Tuesday morning August 22 it was mapped at 97,758 acres, approaching the 100,000-acre threshold of becoming a “megafire”.

For the last several days it has been spreading rapidly to the southwest growing to within five miles of Brookings, a community on the Pacific coast. It is 14 miles southeast of Gold Beach.

The Team is using a mixture of direct, indirect and point protection tactics when and where they expect there is a high probability of success. The fire is burning in areas of fire scar and islands that were previously unburned, as well as areas west of the previous fires. The combination of down and dead fuels in the old burns and newly cured grass adds complexity for firefighters.
