...FLOOD WATCH IN EFFECT FROM SUNDAY MORNING THROUGH LATE TUESDAY
NIGHT...

* WHAT...Flooding caused by excessive rainfall is possible.

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

* WHEN...From Sunday morning through late Tuesday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Flooding may occur in poor drainage and urban areas. Area creeks
  and streams are running high and could flood with more heavy rain.
  Landslide risk will also increase through this period.

* ADDITIONAL DETAILS...
  - A series of storms via an atmospheric river will produce
    periods of rain, heavy at times, over western Washington from
    Friday into Tuesday. The heaviest of the rain will be
    concentrated over the Olympics and Cascades, where rain
    totals through this period will range from 3 to 5 inches,
    with locally higher amounts possible. Snow levels will
    increase to above 7,000 feet Saturday evening. These
    conditions could result in flooding in a number of rivers.
