After another round of heavy rains soaked parts of California, Gov. Jerry Brown declared a state of emergency late Monday for several counties dealing with an estimated tens of million dollars in damage from flooding, erosion, and mud flows. The governor’s order cited the destruction to roads and highways from the so-called atmospheric river that has pummeled Southern California, the Central Coast, the San Joaquin Valley and the Bay Area since early January. A second emergency declaration was also issued for a spate of Northern California counties battered by rainstorms.
