Southern California firefighters continue to patrol the big wildfire burn area near Camarillo and Thousand Oaks.
The Ventura County Fire Department said Wednesday that as vegetation dries out following light rain, hot spots are igniting and producing smoke in the interior of the burn area.
The fire erupted May 2 along U.S. 101 about 50 miles west of Los Angeles and threatened about 4,000 homes before weather turned damp.
The fire was estimated to have scorched nearly 44 square miles, but firefighters have now more accurately measured, reducing it to nearly 38 square miles.
In Northern California, a 10.7-square-mile wildfire in Tehama County is 90 percent contained and expected to be fully surrounded Thursday. The fire began last week northwest of Butte Meadows, about 200 miles north of San Francisco.
