The King County Flood Warning Center has issued a Phase 2 flood alert for the Green River, where some minor flooding could be expected in low-lying areas upstream of Auburn.


The King County Flood Warning Center, whichFlood Control Zone District Logo has been operating continuously since the evening of Tuesday, Nov. 21 to monitor rain-swollen rivers across the county, has issued a Phase 2 flood alert for the Green River.

• The Snoqualmie River remains at a Phase 3 flood alert level, with moderate and widespread floodwaters still affecting areas along the river from Carnation through Duvall;
• The South Fork Skykomish River in the northeastern corner of the county is at a Phase 2 flood alert level;
• The White River also remains at a Phase 2 flood alert level, with minor flooding in low-lying areas along the river in the Auburn-Pacific area.
