...FLOOD WATCH REMAINS IN EFFECT THROUGH THURSDAY AFTERNOON...

The Flood Watch continues for

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

* Through Thursday afternoon

* Rainfall totals of 2 to almost 5 inches have fallen over the
Olympic Mountains, with 1 to 4 inches at Mount Rainier and
around 1 to 3 inches further north over the Cascades. The snow
level is around 9000 feet. Rain will continue at times tonight
and Wednesday, though amounts will be less that what occurred
today. A second frontal system will bring another 1 to 4 inches
of rain Wednesday night and Thursday, with the snow level
falling from 7000 feet to 4000 feet as the system moves through.

* The two systems in close succession present a threat of flooding
on rivers in Western Washington. Flooding could begin tonight or
Wednesday. It looks like the threat is for a relatively minor
flooding episode. Some of the rivers to be at risk the earliest
include the Snoqualmie, Nooksack, White, Tolt, and Skykomish
Rivers. Many others are at risk as well. Check out our website
and the Advanced Hydrologic Prediction Service webpage for
details.

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.
