The SCU Lightning Complex of fierce blazes, as of 7 p.m. Sunday was at 92 percent control, after having burned 396,624 sections of land in Santa Clara, Alameda, Contra Costa, San Joaquin, Stanislaus, Merced and San Benito provinces, Cal Fire said.

Full control of the fire, which has presently broken off into two fundamental “branches,” isn’t anticipated until Sept. 12.

The fires started Aug. 16 in several locations by lightning strikes. No one has died in any of the fires, but five people have been injured, and 136 homes and other structures have been destroyed.

Cal Fire said hot, dry conditions allowed for increased smoldering of hot material in the interior portions of the fire complex, now mostly in the Santa Clara, San Joaquin and Stanislaus County areas east of San Jose and into the Central Valley.

Temperatures above 105 degrees, and humidity being in the low teens and single digits, will make fire conditions more critical, Cal Fire said, and excessive heat warnings remain in effect in the fire zone.
