 Greg Clugston, Washington. Crews are fighting around a dozen wildfires in California, including one that's forced people to flee their homes in Oroville in northern California. The fires are burning in the midst of a stubborn heat wave that shows no sign of letting up. The heat in the west in particular looks to persist through the week, and if you look at the extended outlooks, the overall pattern favors above normal temperatures even going out a couple weeks from now.
