Lightning and arson sparked several new blazes as wildfires raged Tuesday through national forests from central California down to San Diego, threatening more than 100 homes and prompting evacuations.
Fires since Saturday have burned 10 homes and nearly 20,000 acres of chaparral and timberland and injured about two dozen firefighters, most suffering from heat exhaustion.Two large fires that began Saturday were more than 90 percent contained early Tuesday. Eight others, including six that started Monday, remained out of control.
A 2,430-acre fire in Riverside County east of Los Angeles threatened about 100 homes Tuesday, said Capt. Mike Gray of the California Department of Forestry.
Federal, state and local crews working 12-hour shifts in heavy protective gear sweltered in temperatures that topped 100 degrees in some spots Monday. More high temperatures were expected.
