  • An estimated 16 million people in California are under flood watch ahead of an incoming storm that could dump five to six inches of rain over central and northern parts of the state, including the San Francisco Bay Area.
  • The impending system is expected to carry with it an atmospheric river (a long, narrow band of moisture carrying warm air and water vapor from tropical climates) into the heart of the state, compounding the already-increased threat of flooding due to recent snowstorms, according to CNN.
