432 PM PDT Thu Mar 19 2026



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



* WHAT...Flooding caused by excessive rainfall continues to be 

  possible.



* WHERE...Portions of northwest and west central Washington, 

  including the following counties, in northwest Washington, Skagit 

  and Whatcom. In west central Washington, King and Snohomish.



* WHEN...Through Friday afternoon.



* IMPACTS...Excessive runoff may result in flooding of rivers, 

  creeks, streams, and other low-lying and flood-prone locations.



* ADDITIONAL DETAILS...

  - An additional 2 to 4 inches of rain are expected over the

    North and Central Cascades through Friday. Rainfall rates in

    the mountains will peak into Friday. This will create a

    double (or even triple) crest scenario on Friday, pushing

    some rivers back above flood stage. The Snoqualmie and

    Snohomish Rivers will likely remain above flood stage. The

    rivers most likely to go back above flood stage Friday are

    the Skykomish and Tolt Rivers. New rivers likely to exceed

    flood stage are the Stillaguamish and Skagit Rivers, with the

    latest forecast showing the Skagit River to rise into

    Moderate Flood stage and just below Major Flood stage.
