On Tuesday the Pioneer Fire in central Idaho continued its march to the north, adding another 16,000 acres to bring the total to over 157,000 acres. Burning 32 miles northeast of Boise and 23 miles west of Stanley, it has been creating huge convection columns rising 30,000 feet into the atmosphere for the last two days.

Most of the growth on Tuesday was on the north side while it was pushed by an 8 to 12 mph wind gusting at 18 to 24 that was variable, but mostly out of the south. As we write this at 2:50 p.m. on Wednesday, the wind so far today has been out of the west and northwest at 4 to 10 mph with gusts of 16 to 24. The smoke being pushed to the east will probably make the air quality rather unpleasant in Stanley, due east of the fire.

The fire was very active late into Tuesday night due to the low relative humidity which ranged from 24 to 30 percent during the night at the White Hawk weather station at 8,344 feet elevation. At 2:33 p.m on Wednesday it was 66 degrees with 21 percent humidity.

Soberanes Fire

This fire has been eating through the brush, grass, timber, and poison oak in the coastal mountains south of Monterey since July 22. In that time it has spread mostly to the south blackening over 91,000 acres.

The only large heat sources a satellite 200 miles overhead was able to detect in the last 24 hours were near the perimeter on the south and southeast sides. The Soberanes Fire is being fought by 1,4913 personnel including 21 hand crews; 65 engines; 12 helicopters; 21 dozers; and 14 water tenders.

The fire was caused by an illegal, unattended campfire on the Soberanes Canyon trail in the Garrapata State Park. The suppression costs to date are $160 million.

Poison oak is very prevalent in the area and some firefighters are saying it is the worst they have even seen. Five hundred have reported to the fire’s medical units for poison oak related ailments, with 200 cases in the past three days.

Rey Fire

The Rey Fire north of Santa Barbara has been working its way east over the last several days but that growth has slowed as firefighters make progress by constructing direct firelines on the fire’s edge and completing contingency lines out ahead of the fire.

The Rey Fire typically slows to a crawl late at night when the marine layer moves in, then the activity increases in the afternoon. The incident management team is calling it 33,006 acres. Approximately 1,976 personnel are assigned to the fire, including 57 hand crews, 99 engines, and 18 helicopters.

Chimney Fire

The Chimney Fire near the central California coast has continued to spread to the north over the last few days through very rough and remote country east of the Hearst Castle.

Over the last two days the Chimney Fire north of Cambria near the central California coast has grown by over 10,000 acres, and has now blackened a total of 40,800 acres. Most of that expansion has been on the north side where it has moved another mile and a half into Monterey County. Late Tuesday evening and into the night it was also very active on the southwest side spreading about a mile to the southwest. It is now 2.7 miles from the Hearst Castle. Some of the additional acres on the west side are a result of firing operations by firefighters.

CAL FIRE has updated the information about the impact the fire has had on structures, reporting that 45 residences and 20 other structures have been destroyed, while 7 have been damaged.

On Tuesday the fire behavior was described as extreme after the inversion broke as usual at about 2 p.m. Firefighters have taken advantage of favorable weather conditions at night to conduct firing operations to secure firelines. One of their priorities is burning out an area on the west side that would protect the Hearst Castle.

Evacuation orders are still in place for some areas in San Luis Obispo and Monterey Counties.

The Chimney Fire 7 miles north of Cambria near the central California coast was very active Sunday on the north and northwest sides where it spread 2.5 miles further north in about 24 hours. The fire is well established north of the western arm of Lake Nacimiento. It expanded by over 7,000 acres, growing to 31,664 acres.

There has been no update from CAL FIRE about the number of structures destroyed since they reported that 48 have burned and another 7 have been damaged.

Late in the day and Sunday night the fire behavior was extreme and continued to challenge the control lines. It is currently burning through the Rock Butte area and has crossed into Monterey County. After the Monday morning inversion dissipates, south and southwest winds will increase to 10 mph with gusts around 20. Snags continue to be a safety hazard for firefighters.

Evacuation orders are in place for Christmas Cove, Oak Shores, Lake San Antonio, and Bryson Hesperia affecting 2,448 people.

The spread of the fire was described as extreme on Saturday and Saturday evening. Drought-stressed timber, chaparral, and grass continue to challenge firefighters in the steep inaccessible terrain as the fire continues to move north and west.
