The King County Flood Warning Center closed at 6 a.m. on Friday, Nov. 24, after about 60 hours of round-the-clock operation in response to flooding on several rivers.
The Flood Warning Center opened at 7:15 on Tuesday, Nov. 21, when the Snoqualmie River spilled its banks and caused minor flooding following several hours of heavy rainfall. The Snoqualmie River eventually rose to a moderate Phase 3 flood alert level, with flooding throughout much of the Snoqualmie Valley.
The South Fork Skykomish, Tolt, White and Green rivers all reached Phase 2 flood alert levels, with minor flooding occurring in low-lying areas.
Flood Warning Center employees will continue to monitor stream gauges and weather reports. Real-time river level information is available online at kingcounty.gov/flood.
King County offers free access to KC Flood Alerts, an automated system that allows subscribers to receive customized alerts of potential flooding for any or all of King County’s seven major river systems.
Immediate notifications about pending high water are sent to email, smart phone text or voicemail, providing subscribers with the maximum amount of warning about potential high water.
Find the KC Flood Alerts link at kingcounty.gov/flood. This website is a valuable preparedness resource, with all of the latest information about river levels and road conditions, plus weather reports and other critical links.
Updated information on flooding is also posted on the King County website at kingcounty.gov.
