Watches & Warnings

Areal Flood Watch
Issued: 3:39 PM PDT Oct. 20, 2017 – National Weather Service

... Flood Watch now in effect from Saturday afternoon through late
Sunday night...

The Flood Watch is now in effect for

* portions of northwest Washington and west central Washington,
including the following counties, in northwest Washington,
Clallam, Grays Harbor, Jefferson, Kitsap, Mason, Skagit, and
Whatcom. In west central Washington, King, Lewis, Snohomish,
and Thurston.

* From Saturday afternoon through late Sunday night

* heavy rain is forecast to fall Saturday afternoon through
Sunday afternoon. The period of heaviest rain will be Saturday
night with the focus of rainfall in the Cascades from about
Stevens Pass southward. Less rain is forecast for the north
Cascades and Olympics. There is still a chance the heavy rain
could spread to the northern Cascades and Olympics. The Flood
Watch remains in effect for all counties in western Washington
with the exception of island and San Juan counties.

* Minor flooding is forecast on most rivers flowing out of the
Cascades from the Skykomish river southward, with a few rivers
cresting in the moderate flood category. Other rivers in the
area could also flood. In addition, urban and small stream
flooding is possible beginning Saturday night.

* The headwaters of Greenwater river is in the Norse Peak fire
burn scar and could see greater than normal flows with heavy
rain.

* Soil moisture is still relatively dry below the surface since
there has not been enough rainfall accumulation over a long
enough period yet this wet season. While an isolated landslide
is possible in western Washington with any rainstorm, and
especially with high intensity rain, soil moisture conditions
have not yet significantly increased the landslide threat. This
storm will bring conditions close to that threshold.

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.
