Flood watch in effect from late tonight through Friday evening for portions of west-central and northwest Oregon... The national weather service in Portland has issued a flood watch for a portion of northwest Oregon, including the following areas, cascade foothills in lane county, central coast range of western Oregon, central Oregon coast, central Willamette valley, and south Willamette valley.
From late tonight through Friday evening rivers are already running high from periods of heavy rainfall and snowmelt this week. Additional heavy rain Wednesday night and Thursday may be enough to push a few rivers above flood stage. At this point, rivers of most concern include the Siuslaw River in western lane county and the Mohawk River in eastern lane county.
Any flooding that occurs is expected to be relatively minor. Note that the mainstream Willamette will be running high through the weekend, but is expected to stay below flood stage.
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.
More information... Flooding possible for some rivers in the central and south Willamette valley and central coast range of western Oregon...another round of heavy rain Wednesday night and Thursday will cause additional rises on northwest Oregon rivers. With several rivers already running high due to rainfall and snowmelt this week, minor flooding is possible Thursday and Friday.
