King County Flood Warning Center opens to monitor possible minor flooding on Snoqualmie River
Dec. 10 – 10:45 a.m.
Persistent rainfall across eastern King County early Sunday morning has brought the Snoqualmie River up to a minor flood level, and the King County Flood Warning Center opened at 10:15 a.m. to monitor conditions.
As of 10:30 a.m. on Tuesday, Dec. 5, the sum of the Snoqualmie River’s three forks had just exceeded the Phase 2 flood alert threshold of 12,000 cubic feet per second, which means it’s possible we could see some minor flooding in low-lying areas along the Snoqualmie River. Some roads could overtop with floodwaters, including Neal Road Southeast, Reinig Road, West Snoqualmie River Road, Snoqualmie Meadowbrook Road and Mill Pond Road.
Sunday’s minor flooding along the Snoqualmie River comes on the heels of more significant and widespread flooding last week on a handful rivers in King County following a series of heavy rainstorms. Additional river flooding is not expected at this time, with only isolated and intermittent showers expected over the next few days.
