Red Flag warnings for the critical combination of low humidity and strong winds expired for a swath of Southern California at midmorning but a new warning was scheduled to go into effect Saturday in the fire area due to the predicted return of winds. The so-called Thomas Fire, the fourth-largest in California history, was 35 percent contained after sweeping across more than 394 square miles (1,020 sq. kilometers) of Ventura and Santa Barbara counties since it erupted Dec. 4 a few miles from Thomas Aquinas College.
