(1) More than 100 homes have been evacuated over fears of mud slides near Los Angeles after the Pacific storm, dubbed a "bombogenesis" or "weather bomb," parked itself over southern California, opening sinkholes and cutting power to thousands of people.
    More than 300 flights at Los Angeles international airport have also been cancelled or delayed. The storm stretched far out into the ocean and was at its strongest late on Friday afternoon. (2) It is expected to last until Saturday afternoon.
    Amtrak cancelled services for much of California’s southern and central coast, and several stretches of road were closed by flooding.
    There were several traffic deaths on wet and flooded roads, but it was difficult to determine which were a direct result of the storm.
    Ryan Maue, a meteorologist for WeatherBELL Analytics, told the LA Times 10 trillion gallons of rain would fall on California in the next week, enough to fill 15 million Olympic-sized swimming pools or to power Niagara Falls for 154 days.
