People living near California’s damaged Oroville Dam can return home, but coming storms could send them packing again. Authorities reduced the mandatory evacuation orders to an “evacuation warning,” meaning they could be forced to evacuate again if the risk increases. A possible threat are storms that could start as soon as tomorrow and last through the weekend. Butte County Sheriff Kory Honea said evacuating nearly 200-thousand people from areas beneath the dam was the right call because it allowed authorities to take action that reduced the level of Lake Oroville. That prevented damage to the emergency spillway that was in danger of failing and will allow the dam hold the runoff from the coming storms.
