Flood Watch Upgraded to Advisory

A flood advisory is now in effect for Cowlitz County until noon tomorrow. The Portland National Weather Service expects light urban and small stream flooding to occur in areas of poor drainage in the south part of Cowlitz County. Rain will continue to fall steadily thorough out the night and into tomorrow. They also advise that landslides and debris flows are possible throughout this event. Structures and roads located below steep slopes, in canyons and near the mouths of canyons may be at risk from rapidly moving landslides. We will monitor later forecasts and watch for a flood warning. At this time, no rivers in Cowlitz County are above flood stage. Another forecast will be issued at 5:00 a.m. tomorrow.
