In Big Basin State Park south of San Francisco — may be a holdover from the fire 9 months ago
Basin Fire at 12:25 PDT May 2, 2021. From PG&E camera.
On Monday firefighters suppressed a fire that burned within the perimeter of the CZU Lightning Complex of fires. The blaze was in Big Basin Redwoods State Park south of San Francisco and could be a holdover from the 86,502-acre blaze from August, 2020.
When firefighters hiked into the fire it was less than two acres, but with the assistance of aircraft they stopped the spread after it burned about seven acres.
In January several other holdover fires were found in the footprint of the same fire.

There is a chance that considering the numerous very large fires that spread through California and Oregon last year, and with lower than normal precipitation during the winter, other similar holdover fires will be discovered. In many cases since they are within the burn perimeter, they may not be a serious problem. But if they are in a large unburned island, burning embers lofted into the air could ignite spot fires some distance away, perhaps outside the perimeter where there is an abundance of available fuel.
The Park has been closed for the last 9 months after the fire destroyed most of the infrastructure. On August 28, 2020 the Park released a list of the structures that were known to have been destroyed at that time:
Historic Park Headquarters
Historic (Main) lodge
Ranger Station
Nature Museum
Store
Maintenance Shop
Multiple park residences, including some Saddle Mountain Property structures
Multiple campground bathrooms
Gatehouse
Bridge between North Escape Road and Gazos Creek Road

Cooler weather has slowed some fires, but the August Complex grew by over 16,000 acres Tuesday
Updated August 26, 2020 | 11:38 a.m. PDT
California Fires August 26, 2020.
The growth of the big complexes of fires in California, LNU, CZU, and SCU, has slowed in recent days, but the LNU and SCU Lightning Complexes still gained 4,509 and 5,717 acres respectively in the last 24 hours. The August Complex southwest of Red Bluff increased by 16,097 acres.
(To see all articles on Wildfire Today about the lightning fires in California, including the most recent, click HERE.)
The blazes have charred more than 1.32 million acres, killed seven people, and destroyed nearly 2,000 structures. The fires are being fought by 280 hand crews, 2,400 fire engines, 300 dozers, and 370 water tenders for a total of 15,000 personnel.
In addition to the National Multi-Agency Coordinating Group working on a request for firefighting assistance from Australia and Canada, California activated the National Guard for help containing the blazes. On August 23 CAL FIRE issued equipment to 270 soldiers as they were beginning basic fire training at Camp Roberts. Another group of 300 soldiers will arrive next week for training. CAL FIRE will embed with each 20-person crew a Captain and two firefighters for supervision.
Below are updates on some of the largest incidents in California, with data from CAL FIRE and the U.S. Forest Service.
LNU Lightning Complex
Updated August 26, 2020 at 1:13 p.m. PDT
Location: North Bay
Counties: Napa, Lake, Yolo, Solano, Sonoma
Administrative Unit: CAL FIRE Sonoma-Lake-Napa
Acres: 357,046. The largest fire in the complex is the Hennessey Fire, 299,763 . The Walbridge Fire west of Healdsburg is 54,923, and the Meyers Fire on the coast north of Jenner is 2,360.
Notes: Fire activity has lessened due to favorable weather conditions and increased humidity across the complex. Deep seated heat still remains in the bottom of the steep, inaccessible drainages. During the evening fire crews held existing control line around the fire perimeter continuing to both reinforce and add new containment lines. When weather and conditions are favorable there will be a controlled burn operation inside the control line. This controlled burn will widen the buffer and consume fuel between the edge of the fire and the control line.
CZU August Lightning
Updated August 26, 2020 at 1:13 p.m. PDT
Location: South Bay
Counties: San Mateo, Santa Cruz
Administrative Unit: CAL FIRE San Mateo-Santa Cruz
Notes: It is burning in Southern San Mateo County and Northern Santa Cruz County actively above the marine layer in the heavy timber and thick undergrowth. Approximately 77,000 people have been evacuated.
River and Carmel Fires
Updated August 26, 2020 at 1:13 p.m. PDT
Location: Five miles south of Salinas, near Pine Canyon Rd. and River Rd.
Notes: Firefighters patrolling the fire Tuesday confirmed that the fire remained within containment lines. The onshore winds from the northwest allowed the fire to travel very slowly to the south with in containment lines.The Carmel Fire 2 miles southwest of the River Fire has burned 6,901 acres and destroyed 37 structures.
Dolan Fire
Updated August 26, 2020 at 1:13 p.m. PDT

Notes: Fire behavior was moderate throughout Tuesday night. Crews performed structure defense in the Julia Pfeiffer Burns State Park and continued to protect private property and clear roadways around Partington and along Hwy. 1. Crews continued to secure direct and indirect lines to keep the fire out of Hermitage, Lucia and Morning Glory. Progress is slow due to rough terrain and lack of available crews. On Wednesday, crews will continue to focus on the northern and southern edges of the fire by constructing and enhancing control lines, with the priority being lines along McWay ridge and above Lucia northeast to Twin Peaks.
August Complex
Updated August 26, 2020 at 1:13 p.m. PDT

Structure protection is continuing when it is safe to do so. Line construction is continuing on the Glade Fire (18,307 acres 0% contained). Firefighters are working in coordination with Crane Mills Timber and using dozers to tie in the north portion of the Tatham fire (8,958 acres 11% contained). .
Red Flag Warning in effect for Northern California Sunday and Monday
August 24, 2020 | 7:45 a.m. PDT

As if firefighters and residents evacuating or battling lightning-caused wildfires in California didn’t already have enough to worry about, another round of dry lightning is in the forecast for Sunday and Monday.
Thunderstorms with little or no rain is what ignited over 500 fires earlier last week. Now scattered or isolated dry thunderstorms could hit northern California and portions of Nevada, Utah, Wyoming, and Colorado through Monday.
Nick Nauslar, a Fire Meteorologist at the National Interagency Fire Center in Boise, wrote about the forecast in a tweet at 11:30 p.m. Saturday:
Hundreds of new fires are likely if this event pans out. And thunderstorm outflow winds will impact some ongoing fires which would lead to an increase of fire spread/behavior. I hope I'm wrong and this forecast busts. But for now, data points to another big event.
So it’s not just the potential for new fires that that is cause for concern — the strong outflow winds associated with the thunderstorms could greatly increase the rate of spread of the existing fires. It can also put firefighters in even greater danger as the winds can shift 180 degrees very quickly changing the direction a fire is moving, possibly overrunning personnel.
(To see all articles on Wildfire Today about the lightning fires in California, including the most recent, click HERE.)
Check out this video showing the effect the passage of a thunderstorm had on the just-ignited Hennessey Fire August 17 in Napa Valley. That fire has now burned 287,811 acres. The effect of outflow winds is temporary, but a blaze that is suddenly much larger can outstrip the ability of firefighters to quickly suppress it.
Red Flag Warnings are in effect for the northern half of California through Monday evening. The highest threat of dry lightning is Sunday afternoon through Monday morning.
With existing shortages of personnel, equipment, engines, and firefighting aircraft, more fires would put further strain on the systems that are already being managed at the highest planning level nationally, Preparedness Level 5. In PL 5 over 80% of the nation’s incident management teams and wildland firefighting personnel are committed to incidents. Resource orders are being prioritized to fires across California and the west.
Aircraft that can map a fire using infrared imagery have not yet flown all of the large incidents and some maps and acreages are estimates. One of the two mapping aircraft owned by the U.S. Forest Service, N144Z which is the most capable, has not successfully mapped a fire since November 16, 2018 because an avionics issue has not been repaired. The Forest Service has hired privately owned mapping aircraft in an attempt to fill the void.
Below are updates on the largest incidents in California.
LNU Lightning Complex
Updated August 24, 2020 at 7:38 p.m. PDT
Location: North Bay
Counties: Napa, Lake, Yolo, Solano, Sonoma
Administrative Unit: CAL FIRE Sonoma-Lake-Napa
Acres: 350,030. The largest fire in the complex is the Hennessey Fire, 293,602. The Walbridge Fire west of Healdsburg is 54,068, and the Meyers Fire on the coast north of Jenner is 2,360.
Notes: The fires continue to actively burn above the marine layer in the heavy timber and thick undergrowth. Damage Inspection Teams have begun to survey areas where fire activity has diminished and it is safe to do so. The number of destroyed structures reflected may change as teams continue to make progress. Firefighting resources are limited due to the number of fires burning throughout California. Limited visibility due to smoke is hampering aircraft operations. Approximately 77,000 people have been evacuated.

River and Carmel Fires
Updated August 24, 2020 at 7:44 a.m. PDT
Location: Five miles south of Salinas, near Pine Canyon Rd. and River Rd.
Notes: The Carmel Fire 2 miles southwest of the River Fire has burned 6,695 acres and destroyed 37 structures.
Dolan Fire
Updated August 23, 2020 at 9:31 a.m. PDT
Location: on the coast 10 miles south of Big Sur
Counties: Monterey
Administrative Unit: U.S. Forest Service, Los Padres NF
Acres: 19,287
Structures destroyed: 0
Personnel assigned: 488
Evacuation information:
Notes: On private land and the Los Padres National Forest, threatening the communities of Hermitage, Partington Ridge, and Lucia. Multiple businesses, communications sites, parks and recreational sites are also threatened. On Saturday crews continued to focus on point protection operations around Hermitage and Lucia to the South, and Partington Ridge and Anderson Peak communications infrastructure to the North. As the threat diminishes these priorities will shift. After more resources arrive the plan will expand to include additional perimeter control operations. The fire was mapped for the first time Saturday night with a fixed wing aircraft. This accurate method is the reason for the large increase in the known acreage.

Saturday, on the seventh day after a 72-hour lightning bust started hundreds of wildfires in California, firefighters are stretched thin attempting to suppress the blazes and protect residents and property. Shortages of personnel, fire apparatus, and aircraft are showing up statewide.
(To see all of the articles on Wildfire Today about the lightning-caused wildfires in California, including the most recent, click HERE.)
Nearly 12,000 firefighters are battling over 20 major fires and complexes of fires in California, most of which were started by about 12,000 lightning strikes. There have been 560 new fires in the last week, primarily a result of the lightning. Firefighters contained a large majority of the blazes, but in spite of their best efforts, over 771,000 acres had burned through Friday prompting evacuations of 175,000 residents. About 96 percent of CAL FIRE’s engines are committed throughout the state. The fires have killed at least five people and injured 33.
Governor Gavin Newsom said in a news conference Friday that he has requested the assistance of Australian and Canadian firefighters.
We’ve also reached out across the border into Canada for resources and support. And many of you up here recall, I think it was 2017, the support that we were provided and the support we provided in turn of some of the best wildfire firefighters in the world from Australia. We also have requests out for that talent as well.
The ability for the U.S. to send firefighters to assist Australia and New Zealand is authorized in a formal agreement under the Emergency Wildfire Suppression Act. Last winter the U.S. sent over 150 firefighters to assist with bushfires in Australia, and has been the recipient of assistance from down under on several occasions.
The Monterey Herald reported that due to the River and Carmel Fires prospective visitors to Monterey County have been asked to delay their travel plans. A joint statement released from U.S. Rep. Jimmy Panetta and four local politicians said, “We also ask anyone considering travel to Monterey County to delay your travel plans. This will ensure that already limited local resources are not strained.”

Firefighters in northern California are struggling for the sixth day with the aftermath of 10,800 lightning strikes that hit the area during a 72-hour period that began Sunday. Since there was not much rain with the lightning, over 300 fires started. Most of the blazes are under control, but still remaining are over 450,000 acres on active fires, and in some areas, the remains of structures that were destroyed. CAL FIRE spokesperson Jeremy Rahn described the situation as a “historic lightning siege.”
(To see all of the articles on Wildfire Today about the lightning-caused wildfires in California, including the most recent, click HERE.)
At least four people have died; a pilot whose helicopter crashed while dropping water on a fire near Coalinga, a PG&E worker, and two other civilians.
The fires are so numerous that three groups of fires have been formed, called “complexes”. This simplifies the organization and reduces confusion and duplication of personnel.
According to CAL FIRE more than 50,000 residents in California have evacuated because of the fires. On the four largest fires and complexes, CAL FIRE reports that 540 structures have burned, a number that includes residences, commercial, and outbuildings.
All non-essential personnel at Travis Air Force Base south of Vacaville were told Wednesday night to evacuate. They were ordered to not exit through the Main or Hospital Gates, but to instead use the North and South Gates.
The 50 patients that were at the 151-bed St. Helena Hospital northeast of St. Helena were ordered to evacuate.
Shortages of aircraft and firefighters are hampering the suppression of the fires. The dry, windy, and very hot weather conditions which are expected to continue through the weekend make control of any vegetation fire difficult even when an adequate number of resources are available.
The largest of the complexes is the LNU Lighting Complex. As of Thursday it had burned 215,000 acres in Napa, Lake, Yolo, Solano, and Sonoma Counties. The Hennessey Fire within the complex stretches for 45 miles north to south. It spread into the outskirts of Vacaville and crossed Interstate 80 between the city and Fairfield. As of Thursday night firefighters had been able to limit the burned area south of the Interstate.
Two other complexes are in the South Bay area, and the River Fire is south of Salinas.
The information below is updated when the data is provided by CAL FIRE.
