HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
538 AM PST Sun Feb 24 2019

...Significant Rainfall from Monday through Tuesday Night May
Result in Flooding, Especially in the North Bay...

* WHAT...A strong Pacific storm with very moist air (Atmospheric
  River) is expected to bring moderate to heavy rain to Northern
  California. Heavy rain on saturated soil will lead to rapid
  rises of area rivers, streams, and creeks. Flooding may result
  if heavy rain develops as expected. A Flood Watch is in
  effect for the North Bay counties of Sonoma, Napa, and Marin
  from Monday afternoon through Wednesday Night.

* WHERE...Areas from Santa Cruz County northward will probably see
  the the heaviest rainfall, while the most prolonged heavy rain
  is most likely to impact the North Bay. Smaller streams and
  creeks throughout the San Francisco Bay Area will likely
  experience significant rises and may flood. Flash Flooding
  potential is highest for the North Bay. In addition, some larger
  rivers such as the Russian River may flood.

* WHEN....Monday through Wednesday. Heaviest rain and flash
  flooding potential is expected from Monday afternoon through
  Tuesday night, but flooding potential on larger rivers such as
  the Russian River will persist through Wednesday night, well
  after heavy rain has ended.

* ADDITIONAL DETAILS...In addition to the flood potential, mud,
  rock, and debris flows could occur in areas of steep terrain,
  including across recent burn scars. Locally strong and gusty
  winds may result in downed trees, and power outages will be
  possible.
