A furious storm unleashed from a "bomb cyclone" over the Pacific Ocean slammed ashore Sunday in drought-plagued Northern California, blasting a wide swath of the West Coast with heavy rain, damaging winds, flooding and mudslides. Over 160,000 homes and businesses in California, more than 170,000 in Washington, and over 28,000 in Oregon were left without power on Sunday due to the extreme weather. Flooding across the San Francisco Bay Area closed streets in Berkeley and inundated the Bay Bridge toll plaza in Oakland, with some roads under two feet of water in San Rafael. The National Weather Service in Sacramento warned of "potentially historic" rain for the city's downtown. North of the state capitol in Butte County, California's Highway Patrol closed down State Route 70 due to mudslides and debris flows near the now-contained Caldor Fire, which scorched more than 346 square miles of the Sierra Nevada and burned hundreds of homes. Although the fire is now 100% contained, wildfires strip away vegetation and prevent the soil from absorbing water, leaving the burned area vulnerable to mudslides and flash flooding. "If you are near a burn scar, it may be too late to evacuate," the weather service in Sacramento said on Twitter. "Do not attempt to cross a debris flow. Take shelter in the highest floor of your home." The storm was forecast to pound some areas with a foot of rain while dumping up to 8 feet of snow over the mountains, forecasters said.
