will result in sharp rises on area creeks, streams and rivers and
will likely result in flooding.

* Impacts include enhanced runoff and associated flooding in low
lying areas and waterways, rising water levels and flooding on
area streams, creeks and rivers. Other impacts include increased
risk of rock/mud slides in steep terrain, downed trees and power
lines, and damaged to or washed out roadways.

Special Statement
Issued: 3:19 AM PST Feb. 20, 2017 – National Weather Service

... Potent storm system and atmospheric river likely to result in
widespread flooding, strong winds and increased threat for
rock/mud slides, shallow landslides and potential debris flows in
hilly terrain and recent burn scar areas through today...

Rainfall and winds continue to increase in coverage and intensity
early this Monday morning and will continue to do so through this
afternoon. Rainfall will be heavy at times, especially in the
North Bay region and along the southwest facing coastal slopes
resulting in the potential for life-threatening flooding. If you
have experienced flooding at any time this winter season, either
near your home or on your daily commute, the potential exists for
additional flooding in these areas during the next 12 to 18
hours.

In addition, southerly winds will increase this afternoon and
result in a heightened threat for downed trees and power lines
with the potential for isolated to scattered power outages. The
combination of heavy rainfall and strong winds will also give way
to widespread rock/mud slides, shallow landslides and potential
debris flows in hilly terrain and recent burn scar areas.

Residents are urged to remain vigilant and encouraged to stay up-
to-date with the lastest weather information throughout the day.
Those taking to area roadways should also check the latest
information from the California Highway patrol and California
Department of Transportation for potential Road closures.
Remember, "turn around, don't drown" when encountering flooded
roadways. It is never safe to drive or walk into flood waters.
