Description
California was impacted by an atmospheric river in late-January, in which more than 7 inches of rain fell from southern California to the central California coast. Rainfall totals exceeded 15 inches in Monterey and San Luis Obispo counties. These heavy rains caused flooding and mudslides in some of the same areas burned by wildfires in late-2020. This combination caused dozens of slides and debris flows damaging homes, vehicles and businesses and infrastructure. Highway 1 south of Big Sur was washed out while the Sierra Nevada range received several feet of snow, closing major highways. In addition to significant rain and snow, high winds also caused extensive power outages across parts the region.
