Summary

A series of powerful storms making their way through the region is prompting flooding and road closures along the swollen Snoqualmie River this afternoon.

Story

A series of powerful storms making their way through the region is prompting flooding and road closures along the swollen Snoqualmie River this afternoon. 

Moderate flooding is already occurring along the Snoqualmie River, with minor flooding occurring on the Tolt River. County road crews continue to monitor road problems and will post additional closures, as necessary. As the higher flows make their way downstream, drivers should be prepared for significant closures, depending on the severity of flooding.

State Route 203 and Woodinville-Duvall Road, key routes providing access to the Duvall, Lake Margaret, Lake Marcel-Stillwater, Lake Joy communities and points east, may need to be closed in the next 24 - 48 hours due to high river flows. These closures could affect the Carnation area as water flows move down river. Closure of these roads would mean virtually all key access routes would be closed for the Snoqualmie Valley.

Depending on conditions, it is possible access could be lost for a day or more. Residents should plan for limited or no access in or out of these communities for  several days as it can take a couple of days or more for water to recede from roadways before they can be safely reopened. Finally, another word of caution: Do not drive around road closure signs or through deep standing water. Driving through flood water can cause your vehicle to stall or lose control, which can have life-threatening consequences.
