The National Weather Service expects that we'll still see heavy rains in Cowlitz County for another 3-4 hours. After that, it should lessen but streams may still rise. There is an Urban Stream and Flood Advisory for Minor Flooding for our area until 1215 today. That means that you can expect small streams to continue to rise with localized rural and urban flooding possible. Excessive runoff from heavy rainfall will cause ponding of water on highways, streets and underpasses, in urban areas with poor or overwhelmed drainage and will also cause elevated levels on small creeks and streams. The National Weather Service warns that in hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to travel across flooded roads. Instead, find alternative routes. It takes only a few inches of swiftly flowing water to carry vehicles away.
Pacificorps has released water twice into the Lewis River and the affected lowland homeowners have been notified. The Cowlitz River at Castle Rock is now anticipated to crest below flood stage this evening. The Cowlitz River at Kelso is still anticipated to crest a little above flood stage.
