YREKA, Calif. (AP) — Crews battling the largest wildfire so far this year in California braced for thunderstorms and hot, windy conditions that created the potential for more fire growth as they sought to protect remote communities. The McKinney Fire was burning out of control in Northern California’s Klamath National Forest, with thunderstorms a major concern on Sunday. The blaze had grown to more than 80 square miles just two days after erupting in a largely unpopulated area near the Oregon line. In northwest Montana, a blaze sparked in grasslands near the community of Elmo grew to more than 17 square miles after advancing into forest. Crews also are fighting a fire in Idaho.
