An atmospheric river moving into the region this week is expected to make for heavy rainfall along the Cascades. Runoff from this rain, combined with lowland rain, will make for rises along area rivers. These rivers are expected to at least reach Minor and Moderate stage this week. Many rivers are expected to peak Wednesday through Thursday, with a few exceptions like Yakima at Kiona continuing to peak through Saturday. Area Flooding is expected across portions Yakima and Kittitas Counties. Flooding of rivers, creeks, streams, and other low-lying and flood-prone locations is imminent or occurring. The major concern is with flooding in the vicinity of the rivers in both counties more than the area flooding. Flooding along rivers will be swift moving, cold, and erode along the edges of the flow. Debris across roads/bridges may also occur. Practice safe driving habits if encountering a flooded road and remember the saying, "turn around and don't drown!"
