CHICO, Calif. (AP) — Firefighters made progress Saturday against California’s largest wildfire of the year ahead of expected thunderstorms that could unleash fire-starting lightning and erratic winds and erode progress made over the past week. Dry, hot conditions posed similar threats across the fire-stricken West.

“We’re not completely out of the woods yet, but we’re looking very, very good,” CalFire official Mark Brunton said in a video update Saturday. “This is moving at a very fast pace.”
