Firefighters put out fires and clear brush in Hidden in the Hidden Valley area of Ventura Country on May 3rd, 2013.
Update 4:07 p.m.: Firefighters continue to get a handle on containing the 28,000-acre Springs Fire burning in Ventura County.
Ventura County Fire Dept. Spokesman Tom Piranio says crews are working to improve control lines and mop up hot spots in the area.
The eight firefighters treated for minor injuries have all been released, and crews from out of the area continue to demobilize and head back to their cities of origin, Piranio said.
All roads in the area are open and all evacuation orders have been lifted, he said.
7:36 a.m.: Cal Fire reports that the Springs Fire is 80 percent contained. Full containment is expected late Tuesday. Total acreage burned remains at 28,000 acres.
Monday's forecast calls for half an inch of rain in Ventura County, and even less in the burn areas.
"Mudslides are not a big concern at this point, because the rainfall is not heavy enough," said Capt. Mike Lindbery of the Ventura County Fire Department. "Our concern with rain is basically due to rocks, logs and things falling in the area where there is no longer vegetation holding things up."
Still, firefighters building containment lines around a huge Southern California wildfire are now dealing with muddy and slippery conditions as rain moves in.
Ventura County Fire spokesman Tony McHale said Monday that the wet weather has significantly reduced fire activity, but it's also caused crews to work more slowly and methodically.
Investigators have ruled out arson as the cause of the fire that has charred 44 square miles at the western end of the Santa Monica Mountains.
At its peak, the fire threatened some 4,000 houses as it moved through neighborhoods of Camarillo Springs and Thousand Oaks. It damaged 15 homes.
East of Los Angeles, a fire that burned 510 acres in Riverside County is fully contained.
