Areal Flood Watch
Issued: 10:03 AM PST Jan. 17, 2017 – National Weather Service

... Flood Watch remains in effect through late Wednesday night for
parts of northwest Oregon and southwest Washington...

The Flood Watch continues for

* portions of northwest Oregon and southwest Washington...
including the following areas... in northwest Oregon... Coast
Range of northwest Oregon... greater Portland Metro area...
lower Columbia and north Oregon coast. In southwest
Washington... Greater Vancouver area... I-5 corridor in Cowlitz

* with dramatically rising snow levels Tuesday and the onset of
heavy rain Tuesday night... expect moderate to sharp rises on
rivers and creeks draining the Coast Range... Willapa Hills...

flooding that occurs is expected to have minor impacts. The
heavy rain will likely cause urban flooding in the Portland/
Vancouver Metro area as the rain will help melt the existing
snow and ice. Blocked storm drains may also contribute to
ponding of water on streets.

* Rainfall amounts through Thursday... 1 to 2 inches Portland/
Vancouver Metro area... 3 to 6 inches north Coast Range/Willapa
Hills... and 3 to 6 inches South Washington Cascades foothills.

* Rivers and creeks of greatest concern include Johnson Creek in
southeast Portland... the Nehalem in Clatsop and Tillamook
County... and the Grays in Wahkiakum County. However... all of
these are currently forecast to crest just below flood stage.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
