Emergency officials have had to shut down several roads Thursday in Snoqualmie Valley due to flooding along the Snoqualmie River. Two roads in the city of Snoqualmie and several roads in unincorporated King County have been topped by floodwater.

No injuries related to the flooding have been reported.

The localized flooding is the result of heavy rains in recent days falling on already saturated ground.

In Snoqualmie, portions of Boalch Avenue Southeast and Southeast North Street have been closed. Outside the city, King County officials have closed parts of Southeast Reinig Road, Southeast Mill Pond Road and Southeast David Powell Road. The Meadowbrook Way Bridge over Snoqualmie River has also been closed.

All roads in the upper Snoqualmie Valley are expected to re-open by Friday morning, according to city and county officials.

Several roads in the lower Valley have also been closed. They include 

415th Way Southeast (between Uplands Way Southeast and Southeast 141st Street), 308th Avenue Southeast (between state Route 202 and Southeast 31st Street), West Snoqualmie River Road Northeast (between Southeast 24th Street and near Northeast Tolt Hill Road) and Neal Road Southeast (near state Route 203).

The three forks of Snoqualmie River crested shortly after noon Thursday, according to the National Weather Service. NWS gauges recorded a crest of nearly 30,000 cubic feet per second. That is well above the 20,000 cfs threshold for King County’s Flood Phase III.

Snoqualmie emergency officials don’t get worried until the flow tops 40,000 cfs at Snoqualmie Falls, according to Snoqualmie Fire Chief Bob Rowe.

The peak at Snoqualmie Falls was forecast to hit about 32,000 cfs at 5 p.m. Thursday, according to the National Weather Service.

In the lower Valley, the Snoqulamie is forecasted to crest at about 35,000 cfs early Friday morning.

While more rain is forecast for Friday night, the river is not expected to flood again at ths point, according to the NWS.
