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 theĀ 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.
