  Multnomah, Polk, Tillamook, Washington, and Yamhill.

Counties in Washington: Clark, Cowlitz, Pacific, Skamania, and

* WHEN...Through Thursday afternoon.

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

  Landslides and debris flows are possible during this flood event.
  People, structures, and roads located below steep slopes, in
  canyons, and near the mouths of canyons may be at serious risk
  from rapidly moving landslides.

* ADDITIONAL DETAILS...
  - Over the past 24 hours, around 2.5 to 5 inches of rain has
    fallen over the north Oregon Cascades, south Washington
    Cascades, Willapa Hills, north Oregon Coast Range, south
    Washington coast, and northern and central Oregon coast. 1.0
    to 3.0 inches of rain has fallen over the Lower Columbia,
    Cowlitz Valley, and greater Portland/Vancouver metro. This
