Flooding continues to impact region

Updated 5:17 p.m. Feb. 7, 2020

With a forecast of rain through Saturday, communities throughout the region continue deal with the impacts of flooding.

Flooding update

  • The Cedar River is still at Phase 4, which is the highest it has been since 2009. Flows continue to increase. Seattle Public Utilities is planning to take “pulsing” flows of water from above the dam, adding more water to the river.
  • The Snoqualmie River waters in the Carnation area are beginning to recede. The flood that is occurring this week is expected to decrease slowly along the lower Snoqualmie River.
  • Crews prepared for the worst, anticipating possible closure of Route 203. That has not occurred to date and hopefully the worst is behind us.
  • Lake Sammamish is rising with all the outflow from area creeks and rivers. King County is partnering with the City of Bellevue to provide information to local residents about how to obtain sandbags.
  • Issaquah Creek is at Phase 2 and water levels continue to drop.
  • A Washington National Guard high clearance vehicle is in place to use for emergency life/safety evacuation of folks who may become isolated.  
  • The King County Flood Warning Center will remain open as needed over the weekend.

Landslides

All this rain raises the risk of landslides. Check landslide hazards:

During dangerous weather: Reduce your risk of landslides

  • Seek out advisories and warnings during and after intense rainfall events. Check the NOAA Weather Radio, your local TV stations and social media.
  • Don’t assume that highways are safe—watch for collapsed pavement, mud, fallen rock, or other debris on the roadway.
  • Listen for loud or unusual sounds. These can be indicators of an imminent landslide. If you think there is danger, evacuate immediately.
  • Keep away from landslide-prone areas.
