California Fire Map, Updates as Slater Fire More Than Quadruples in a Day

California wildfires have burned over 3.1 million acres of land, with at least 12 people reported dead and 3,900 structures destroyed, according to the latest report Thursday from the California Department of Forestry and Fire Protection (Cal Fire).

Firefighters continue to battle 29 major fires across the state, including the Slater Fire in Siskiyou County. The fire has grown from 30,000 acres reported Wednesday to 127,000 acres by Thursday, more than quadrupling in a day, according to the latest report Thursday from the Incident Information System of the National Wildfire Coordinating Group (NWCG).

More than half of the nearly 5.2 million acres burned by fires across the U.S. were reported to be in California. Six of the top 20 largest wildfires in California history were reported this year, Cal Fire confirmed.

Here are the latest updates on some of the current major fires across California.

August Complex Fire

  • Location: Mendocino, Glenn, Lake, Tehama, Trinity counties
  • Acres: 746,607
  • Containment: 25 percent

Many of the 37 different fires in the Mendocino National Forest that form the August Complex Fire have either been contained or merged, according to the latest report Friday from the NWCG.

"The largest active fire on the August Complex is the Doe Fire, currently at 471,185 acres at 24 percent contained burning in five counties: Glenn County, Mendocino County, Lake County, Tehama County and Trinity County. Actual acreage is subject to change as fire activity progresses throughout the day.

"South easterly winds will continue across the ridge tops through Friday. The winds for the lower elevation and mid-slopes will become terrain driven tonight and through Friday," the report noted.

Evacuation orders are in place for several counties. Contact the respective county sheriffs' offices for more information on evacuations, the Mendocino National Forest advised.

North Complex Fire

  • Location: Yuba, Plumas and Butte counties
  • Acres: 244,203
  • Containment: 23 percent
  • Fatalities: 3

The complex fire is spread across three areas—the North, South and West zones—which includes the Bear Fire, renamed by Cal Fire as the North Complex West Zone Fire. It has spread to 67,295 acres, with zero percent contained.

Seven more fatalities were reported from the North Complex West Zone Fire, bringing the total to 10, while 16 of the 124 people reported missing remain unaccounted for, the Butte County Sheriff's Office's confirmed.

"The weather continues to work in the firefighters favor with decreased winds, lower temperatures, and higher humidities...however the lack of visibility continues to be a factor, as heavy smoke in the area of the fire hampers the ability of aircraft to fight the fire from above," Cal Fire noted in its latest report Thursday.

Evacuation orders and warnings as well as road closures are in effect across several parts of Yuba, Plumas and Butte counties. See Cal Fire's full report for more details.

The #BearFire in Butte County has a new name. It will be referred to from now forward as the #NorthComplexWestZone. Here is the morning update and a Public Information map of the fire.

Creek Fire

  • Location: Fresno and Madera counties
  • Acres: 175,893
  • Containment: 6 percent

In Fresno County, winds will ease over the blaze as high pressure builds overhead, with temperatures returning to seasonal averages, while relative humidity will remain low, Cal Fire noted Thursday.

"On the southern fire flank, from Davis Mountain to the San Joaquin River, firefighters are monitoring for spotting as down-canyon winds develop. In the vicinity of Shaver Lake, there is potential for the fire to spread further east and south," Cal Fire added.

Over in Madera County, the department noted "a thick smoke layer continues to moderate fire activity on the west flank."

Evacuation orders remain in effect for Madera County's Bass Lake Basin, including Wishon, Bass Lake Annex, and Manzanita, the town of North Fork and surrounding area.

Evacuation warnings and road closures have been issued for several parts of Fresno and Madera counties. See Cal Fire's full report for details.

Slater Fire

  • Location: Siskiyou County
  • Acres: 127,000
  • Containment: 0 percent

The fire was reported to have been active throughout Thursday, "despite lower winds and a heavy smoke inversion that sat over the fire through most of the day," according to the latest report Thursday by the NWCG.

"A heat-detection flight yesterday showed a second fire burning east of the Slater Fire, north of Upper Devil's Peak on the Klamath National Forest. Estimated at 2000 acres this evening, the Devil Fire is currently unstaffed and uncontained. The cause of the fire is currently unknown," the report noted.

Evacuation warning has been issued for "the area along Highway 96 and north to the Oregon Border between O'Neil Creek Campground and the mouth of the Scott River.

Bobcat Fire

  • Location: Los Angeles County
  • Acres: 23,890
  • Containment: 6 percent

Winds were reported to have pushed the Bobcat Fire northeast on Thursday.

"The northern portion of the fire has reached up into ridges near Angeles Crest Highway where retardant drops have been made. Steep terrain and dry fuels, some of which haven't burned in the last 60 years, will create challenges for crews," according to the latest report Friday from the NWCG.

"Continued warm and dry conditions with poor humidity recovery along the ridgetops will allow active burning and fire growth through the night. Another trend toward abnormally high temperatures is expected through the weekend," while poor air quality due to smoke cover is expected to continue Friday, the NWCG report warned.

Evacuation warnings remain in place for the areas including Monrovia, Arcadia, Bradbury, Sierra Madre, Altadena, Duarte and Pasadena, the report noted.

The #BobcatFire is 23,890 acres with 0% containment. Overnight, fire crews saw heavy activity in the northeastern portion of the fire towards Crystal Lake. For more info visit:
