"Major" atmospheric river storm hits California amid "relentless" rains"
"The most powerful in a "relentless parade" of atmospheric rivers is bearing down on California today through Wednesday. It brings with it the likelihood of widespread flash flooding, river flooding, mudslides and staggeringly high mountain snowfall totals. Why it matters: The whiplash from a bone dry to flood-prone state is a demonstration of how human-caused climate change is accentuating California's naturally fickle precipitation patterns. While flooding, power outages and landslides threaten Californians in the near-term, these storms are boosting reservoir levels, severely depleted by the Southwest's megadrought. State of play: Late Sunday, President Biden approved California's emergency declaration due to the atmospheric river storms, as requested by California Gov. Gavin Newsom. This will allow federal aid to begin flowing to the state. An estimated 133,000 customers were without power on Monday morning, as the Office of Emergency Management issued evacuation warnings for several areas in Santa Barbara County "due to potential flooding and debris flows." Flash flood warnings are in effect for Santa Cruz and Monterey Counties. Evacuation orders have been issued for some communities, including locations along the San Lorenzo River in Felton, which has quickly climbed to major flood stage."
