California Wildfires Update on LNU, SCU, CZU August Lightning Complex Fires

California is currently experiencing three collections of wildfires—the LNU Lightning Complex, the SCU Lightning Complex, and the CZU August Lightning Complex—as well as several other fires.

The three Lightning Complex groups are made up of multiple fires burning thousands of acres across several counties in California, with thousands of residents under evacuation orders and warnings.

Governor Gavin Newsom has secured two Fire Management Assistance Grants  (FMAGs) from FEMA, ensuring the availability of resources to suppress  the LNU Lightning Complex Fire burning in Napa County, as well as the Jones Fire in Nevada County.

Newsom declared a statewide emergency on Tuesday, saying in a statement: "We are deploying every resource available to keep communities safe as California battles fires across the state during these extreme conditions.

"California and its federal and local partners are working in lockstep to meet the challenge and remain vigilant in the face of continued dangerous weather conditions."

Cal Fire said: "Extreme fire behavior with short and long-range spotting are continuing to challenge firefighting efforts.

"Fires are making runs in multiple directions and impacting multiple communities. A critically dry airmass is moving over the area bringing strong winds."

So far, 70 structures have been damaged and 105 destroyed by the fires in the LNU Lightning Complex. There are two agencies, nine crews and 587 personnel working to control the fires in the LNU Complex.

SCU Lightning Complex

The SCU Lightning Complex is made up of several fires burning in Santa Clara County, Alameda County, Contra Costa County, San Joaquin County, and Stanislaus County.

The fires are broken into three zones; the Canyon Zone, the Calaveras Zone, and the Deer Zone. They have collectively burned 102,000 acres and are 5 percent contained.

On Wednesday night, Cal Fire said that the fires "continue to burn in steep, rugged terrain and are influenced by extreme temperatures and low relative humidity. Some of the terrain has little to no fire history with decadent fuels conducive to extreme fire growth.

"Today, smoke and haze kept the inversion in place for much of the day. Westerly winds increased throughout the day with gusts up to 30 mph observed. "

Cal Fire also said that: "Crews were actively engaged in structure defense all day. Fire perimeter and control efforts have been hampered by extreme fire behavior and accessibility issues.

"Tonight, crews will continue to scout for safe access points and build direct and indirect fire line where possible. Crews will also look to strengthen and patrol existing containment lines on the smaller lightning fires."

Cal Fire says that firefighting resources are limited due to the number of fires burning throughout California and that they are also facing poor visibility due to smoke hampering aircraft operations.

Cal Fire is encouraging all residents of California to get ready to leave their homes in case of a wildfire. Cal Fire spokesperson Lynnette Round said on Wednesday: "My recommendation is that all the citizens in California be ready to go if there is a wildfire.

"Residents have to have their bags packed up with your nose facing out your driveway so you can leave quickly. Everybody should be ready to go, especially if you're in a wildfire area."
