Flood alerts issued for some rivers after heavy rainfall

An atmospheric river brought an intense amount of rain to Western Washington from Thursday to Friday, which has prompted river flood alerts for the region. 

As of 10:30 a.m. Friday. the National Weather Service said a Flood Warning is extended for the Skokomish River at Potlatch, affecting Mason County. 

A Flood Warning continues for the Snoqualmie River near Snoqualmie Falls in King County. 

Flood Warnings have been canceled for both the Stillaguamish and Skykomish rivers. 

On Thursday night, the King County Flood Warning Center issued Phase 3 flood alerts for Snoqualmie and Tolt river, as heavy rainfall pushes rivers higher. Phase 3 means moderate to severe flooding is expected, with numerous road closures. Some levee overtopping can be expected. A Flood Warning was also issued, which remains in effect. 

Meanwhile, the Tolt River was flowing at 5,290 CFS at 6:30 p.m. Thursday, just above the Phase 3 flood alert threshold of 5,000 CFS for the Tolt. At these flows, minor flooding could be expected in low-lying areas upstream of Carnation, including areas along Tolt River Road Northeast.

Officials are warning people to proceed with caution when walking near rivers. Also, if a roadway is flooded, do not drive through it. Turn around and seek alternative routes. 

Rain is expected to clear up Friday.
