Flood Forecast for Snoqualmie River: Rising Waters Early Sunday

No significant flooding is expected; some lowland flooding may occur.

The Snoqualmie River near downtown Snoqualmie is currently flowing at approximately 5,200 cubic feet per second* (cfs). Flows are forecast to remain steady through Saturday night, cresting at approximately 35,000 cfs (flood phase 3) on Sunday, December 20 at 10 a.m. according to the NOAA Northwest River Forecast Center.

No significant flooding is expected. Downtown Snoqualmie flooding does not occur until well over flood phase 4, generally toward 60,000 cfs.

Some lowland flooding may occur, such as on SE Reinig Road and Mill Pond Road, which could result in temporary road closures. Residents in areas that experience higher waters during early flood stages are advised to move vehicles to higher ground, such as the parking lot by Snoqualmie Community Park, 35016 SE Ridge St (next to the YMCA).
