Cal Fire said its latest tally confirmed that 567 homes or other structures were destroyed in the blaze, with 427 of them in Butte County. Of the 51 structures damaged by the Park Fire, 46 were in Butte County.

Damage inspection teams have completed 94% of their assessments, Cal Fire said.

Now that hot, dry weather has returned to the area, containment lines that have been constructed "are being tested. Spot fires and active fire behavior are expected to present challenges for fire crews the next several days.

Thunderstorms are expected to continue today and could be more widespread in coverage. Higher temperatures, lower relative humidity and gusty winds could lead to critical fire behavior and plume development," said Cal Fire in its report.In Shasta County, smoke from the Park Fire and other wildfires burning in the region hurt air quality on Saturday, pushing pollution levels into the moderate zone, according to AirNow.
