SAN FRANCISCO (CBS SF) — A series of lightning-caused fires involving several Bay Area counties grew to 35,000 acres Tuesday night and forced more mandatory evacuation orders at the Santa Clara County line, according to fire authorities.

The East and South Bay fires have been grouped together by Cal Fire’s Santa Clara Unit into what is now known as the SCU Lightning Complex fires (map). As of Tuesday evening, the fires were 4 percent contained.

New mandatory evacuations orders issued at 10 p.m. Tuesday cover an area that includes north of 130 to the Santa Clara County line, west of San Antonio Valley Road, west of Mines Road to the Santa Clara County line, east of 3 Springs Road and Mount Hampton Road and the area south of the Santa Clara County line.

New evacuation warnings were issued for east of Ed Levin County Park, Felter Road, Sierra Road, Toyan Avenue and Mt. Hampton Road to 3 Springs Road, north of Mount Hamilton Road to 3 Springs Road, south of the Santa Clara County line and west of the fire perimeter.

The group is comprised of approximately 20 different fires that were sparked by lightning on Sunday and are spread across five separate counties: Alameda, Contra Costa, San Joaquin, Santa Clara, and Stanislaus.

Earlier Tuesday afternoon, there was zero containment on the fires, which are burning in steep, inaccessible terrain, Cal Fire reported. Low humidity and triple-digit daytime temperatures have challenged more than 500 firefighters working the fires; an excessive heat warning is in effect until Wednesday.
