Courtney Carpenter from the National Weather Service stated, 'This one ... will kind of stall out along Northern California and bring many days of moderate to steady rainfall.' They do not expect widespread flooding but anticipate rain to cause issues across the northern part of the state.
The National Oceanic and Atmospheric Administration explains that atmospheric rivers are long, narrow regions in the atmosphere transporting most water vapor outside the tropics, comparing their flow to that of the Mississippi River.
When atmospheric rivers make landfall, they often release powerful moisture as precipitation. NOAA warns, 'Those that contain the largest amounts of water vapor and the strongest winds can create extreme rainfall and floods.'
As the storm approaches Northern California on November 19, meteorologists note the possibility of bombogenesis, a phenomenon leading to the formation of a bomb cyclone, which may exacerbate the storm's effects.
