The complex, sparked Aug. 16 by lightning in various spots, has burned 396,624 acres in seven counties, including three in the Bay Area -- Contra Costa, Alameda and Santa Clara counties.

Recent temperatures between 103 and 110 degrees hampered firefighters and hot and dry conditions remain in the forecast through mid-week.
