King County Flood Warning center closes as immediate flood risk passes with declining rainfall

Oct. 31, 2:15 p.m.
King County closed the Flood Warning Center at noon today following more than 10 hours of operation to monitor rising flows on the Snoqualmie River from a full day of steady rainfall across the eastern portion of the county.

While flows in the lower Snoqualmie River will continue to rise for a few more hours in communities such as Carnation and Duvall as the flood crest makes its way downstream, heavy rainfall in the upper Snoqualmie Watershed has been replaced by more intermittent showers and cooler weather, signaling an end to the threat of additional flooding.

That’s the good news. The not-so-good news is that we’ve got another potential atmospheric river headed toward King County later this week that could lead to another round of river flooding. This next storm’s development is something King County employees will keep an eye on for the next several days.

The lull between storms is the perfect time to make sure you’re set up to get real-time updates on flooding in King County through KC Flood Alerts at kingcounty.gov/flood, where detailed flood preparedness information is available, including the latest on river levels and road conditions, plus weather reports and more.
