Update (1:30 p.m. 8/10 from CAL FIRE): The Canyon Fire is 62% contained with 5,370 acres burned and seven structures destroyed.

Message from CAL FIRE: Firefighters continue to make good progress on the Canyon Fire located to the east of the city of Piru. Crews worked through the night to monitor and extinguish isolated heat sources. Minimal fire activity allowed crews to continue improving control lines. Overnight infrared flights along the northeast portion of the fire identified areas of remaining heat which are being used to guide today’s suppression priorities.

The northeast section continues to have the highest concentration of remaining heat. Infrared mapping taking place today will further help crews locate and extinguish hot spot areas, prevent flare-ups and protect the fire perimeter. Dozer lines on the eastern edge of the fire will be strengthened to minimize the chance of spread. Across the incident, firefighters remain prepared to respond quickly to any flare-ups while suppression repair and backhaul will continue to address impacts from firefighting operations.

Hot, dry conditions will persist today with high temperatures ranging from 96–104°F, relative humidity dropping to 15–20%, and wind gusts up to 20 mph.

Update (6:22 p.m. 8/8): The Canyon Fire is 28% contained with no additional acreage at 5,370 acres, according to the Ventura County Fire Department (VCFD).

After an explosive size-up on Thursday, growth was limited to just over 500 acres on Friday despite “challenging” weather and terrain, VCFD officials said. Three firefighters suffered minor injuries during the firefight and were transported to a local hospital out of precaution and are expected to recover.

Approximately 400 personnel are assigned to this fire, and the cause remains under investigation.
