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

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

  Flooding may occur in poor drainage and urban areas. Storm drains
  and ditches may become clogged with debris. Area creeks and
  streams are running high and could flood with more heavy rain.

* ADDITIONAL DETAILS...
  - An atmospheric river will continue to impact the area through
    much of the week and bring periods moderate to heavy rain to
    the region. Sharp rises are occurring on area rivers,
    especially those flowing off the Olympics and Cascades.

    Urban and small stream flooding is possible for areas with
    poor drainage.

    Saturated soils will bring increased potential for landslides
    and debris flows on burn scars.
