The Fly and Dixie Fires burning in remote parts of Butte and Plumas counties merged together overnight near the town of Twain as emergency crews expect fire conditions to worsen and increase chances of lightning storms Sunday, CalFire officials said.

Almost two weeks after it broke out near the fire-ravaged town of Paradise in Butte County, Dixie Fire spokesman Mitch Matlow said Sunday the blaze is about 21% contained after burning about 190,625 acres and continues to threaten over 10,000 homes.
