SAN FRANCISCO (AP) — Fire officials braced on Saturday for the possibility of lightning-sparked fires across a wide area of Northern California as a number of thunderstorms move into the region.
The California Department of Forestry and Fire Protection increased staffing and was on high alert because of the increased fire danger from so-called dry thunderstorms, agency spokesman Daniel Berlant said.
Fire officials believed lightning sparked two small fires totaling 650 acres, or a square mile, in the Piute Mountains of the Sequoia National Forest.
