A new storm dumped more rain on already waterlogged parts of Northern California on Monday, causing minor road flooding, scattered power outages and airport delays. The rain was coming down hard in the Bay Area early Monday, making for a treacherous commute. A landslide closed both directions of a highway in Fremont. At San Francisco International Airport, the Federal Aviation Administration reported arrival delays of almost two hours. The storm was expected to drop between an inch and 2 inches of rain throughout the morning in the Bay Area and Sacramento regions before heading to Southern California, National Weather Service forecaster Bob Benjamin said. But it and another weather system later in the week won't be nearly as powerful as the storm that dumped as much as 8 inches of rain in parts of Northern California last week and up to 6 feet of snow in the high elevations of the Sierra Nevada. That storm caused widespread flooding and power outages, including in downtown San Francisco. While the storms help, much more rain is needed to pull the state out of its severe drought, forecasters say. The Sierra Nevada is expected to receive a few inches of snow by Monday morning at elevations above about 5,000 feet, a height that includes most ski resorts, said Eric Kurth, a meteorologist in the weather service's Sacramento office. The second weather front is expected to dump yet more rain Wednesday in the Bay Area, Benjamin said. Southern California may get more precipitation Thursday.
