Covington said crews would remain on scene throughout the day to extinguish the remaining fire and monitor hot spots and ensure increasing winds did not reignite the flames, which were still burning in some vegetation and tree stumps. “The elevated temperatures and the heavy winds is what we’ll be watching for,” Covington said. Evacuation orders were still in effect on Saturday as of 11 a.m. for residents in zones OKL-E176, OKL-E177 and OKL-E203. Real time evacuation maps can be viewed here. Covington said the fire department was working to get residents back in their homes by the end of the day, but did not want to send people back in the face of increasing winds, only to have to order them to leave again. Wind speeds were forecast to be between 8-11 mph on Saturday, with gusts up to 20 mph, according to the National Weather Service. The wind, combined with dry conditions, contributed to the Red Flag Warning, which is issued when fire conditions are dangerous. The University of California, Berkeley said it would be taking precautions related to the Red Flag Warning at its football game on Saturday, including suspending live cannon fire and pyrotechnics. Outdoor barbeques will be banned on campus and other food service will be modified with fire safety in mind, according to the University. Two homes were damaged and about a dozen were threatened at the height of the fire. No injuries were reported.
