...THREAT OF RIVER FLOODING REMAINS SATURDAY MORNING THROUGH SUNDAY
FOR PORTIONS OF NORTHWEST WASHINGTON AND THE OLYMPIC PENINSULA...

A stronger storm system will move though the area over much of the
weekend that could produce enough rainfall to drive a few rivers in
western Washington above flood stage. This Flood Potential Outlook
has been issued for Skagit, Snohomish, and Whatcom Counties. It has
been upgraded to a Flood Watch for Mason County.

There is still a fair amount of uncertainty regarding flooding since
the precipitation forecasts have been quite variable. Rainfall
forecasts at this time are for 3 to as much as 5 inches in the
central and north Cascades. The rainfall forecasts have increases
over the north Cascades and especially in Snohomish County and the
Stillaguamish River Basin. Snow levels will remain quite high during
the bulk of the heavy
precipitation, ranging between 7000 and 9000 feet. This will enable
most of the precipitation to turn into storm runoff.

Please monitor the latest river forecasts from the National Weather
Service for additional information.
