Crews worked into the night Wednesday to shore up the emergency spillway at troubled Oroville Dam, racing to fortify the structure before the next series of storms, the first of which was forecast to hit before midnight. Three storm systems will move into Northern California during the next six days, according to the National Weather Service. The first system will drop about an inch of rain in the Oroville area. Greater amounts of precipitation will fall in the mountains northeast of the reservoir.
