Snoqualmie joins Tolt River at Phase II flood alert; King County Flood Warning Center monitoring flows

Additional rainfall Sunday evening prompted the King County Flood Warning Center to issue a Phase II flood alert level for the Snoqualmie River. A Phase II flood alert level was issued for the Tolt River late Sunday morning.

A Phase II flood alert level means minor flooding can be expected in low-lying areas with the possibility of road closures along the identified rivers.

At 9:30 p.m., the sum of the Snoqualmie River’s three forks was 12,210 cubic feet per second (cfs). A Phase II flood alert on the Snoqualmie is issued when the sum flow of the forks reaches 12,000 cfs.

At 9:30 p.m., the Tolt River was flowing at 2,900 cfs at a gauge near Carnation. A Phase II flood alert on the Tolt is declared when flows reach 2,500 cfs.

A Phase II warning on any major King County river is the level of the county's four-phase warning system at which the Flood Warning Center is activated to monitor lowland flooding.

The Flood Warning Center opened at 11:30 a.m. Sunday and will remain open and continue to monitor the river flooding until conditions improve. Flood Warning Center staff will monitor stream gauges and weather reports and provide updated information on river conditions as necessary.

Real-time river level information is available online by visiting: http://dnr.metrokc.gov/wlr/flood/flood.htm.

King County is advising residents living or traveling in flood-prone areas to continue to monitor weather conditions and be on the look out for road closures. Motorists are reminded never to drive through standing water or around barricades; this is how most lives are lost during flooding.
