Department of Forestry and Fire Protection spokesman Daniel Berlant said Monday that several days of rainfall helped the firefighters and that authorities are confident most of the wildfires will be contained this week.
He says the largest fires are more than 90 percent contained.
Officials are almost finished with their assessment of property damage. Berlant says their count of buildings destroyed may rise slightly.
