... Flood Watch in effect from Saturday afternoon through late
Sunday night for much of southwestern Washington and northwestern

The National Weather Service in Portland has issued a

* Flood Watch for portions of northwest Oregon and southwest
Washington, including the following areas, in northwest
Oregon, central Columbia River gorge, central Willamette
Valley, Coast Range of northwest Oregon, greater Portland
Metro area, lower Columbia, north Oregon coast, northern
Oregon Cascade foothills, northern Oregon Cascades, and
western Columbia River gorge. In southwest Washington, central
Columbia River gorge, Greater Vancouver area, I-5 corridor in
Cowlitz County, South Washington Cascade foothills, South
Washington Cascades, South Washington coast, western Columbia
River gorge, and Willapa Hills.

* From Saturday afternoon through late Sunday night.

* Heavy rain expected on Saturday and Saturday night, with
significant rises expected on many streams and rivers.

* Total rainfall Coast Range and Willapa Hills... 4 to 8 inches.
South Washington and north Oregon Cascades... 3 to 7 inches.
Coastal areas... 3 to 6 inches, heaviest north of Lincoln City.
Columbia River gorge... 3 to 6 inches, including Eagle Creek.
Interior lowlands... 1 to 3 inches.

* Rainfall intensity may be enough to trigger flooding and debris
flows downstream of burn scars, particularly near The Eagle
creek fire in the Columbia River gorge.

* While significant rises are expected on many area rivers,
flooding on the Willamette or Columbia River is not expected.
Flooding threat is for smaller rivers, such as the Wilson river
near Tillamook and Johnson Creek in southeast Portland.

* In addition, expect areas of urban flooding due to clogged storm
drains and ponding of water in low areas.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on
current forecasts.

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.

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.
