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

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

* WHERE...Portions of northwest Washington and west central
  Washington, including the following areas, in northwest
  Washington, Clallam, Jefferson, Mason, Skagit and Whatcom. In west
  central Washington, Snohomish Counties.

* WHEN...Through Thursday morning.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Creeks and streams may rise out of their banks. Most likely rivers
  to watch at this time include the Nooksack, Skagit, Stillaguamish,
  Bogachiel, and Skokomish Rivers. Any flooding that does occur will
  likely be minor.

* ADDITIONAL DETAILS...
  - Moderate to heavy rain, along with warm temperatures, breezy
    winds, and high relative humidities will increase snow melt,
    though there is less than normal low and mid elevation snow
    available to melt. Rainfall up to 2 to 4 inches in the
    mountains and 1 to 2 inches in the lowlands, combining with
    snow levels above 10,000 feet, will have rivers rising in the
    watch area and they could see minor flooding. With this
    decently strong atmospheric river just to our north, should
    it slide in a little more to the south, there would be
    potential for flooding on the more northerly rivers to be
    moderate severity instead of minor.
    The additional rain on saturated soils will increase the
    landslide threat as well.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
