King County’s Flood Warning Center closed on Dec. 30 at 4:55 p.m. now that rivers have receded. During the three weeks of activation staff monitored and patrolled rivers, coordinated emergency actions and repairs with partners, and trained members of the National Guard deployed to provide reinforcements by Gov. Bob Ferguson. For a complete overview of operations and resources, read By the numbers: A look back at King County’s response to historic flooding.

The White River returned to flood phase 4 around 3 p.m. today as water releases from the Mud Mountain Dam have increased. Releases from the dam had been lowered by the U.S. Army Corps of Engineers the last several days. This was to help King County and partners make repairs to flood barriers in the city of Pacific. The higher releases from the dam are necessary to quickly increase flood-storage capacity for incoming storm systems.
Early in the morning of Tuesday, Dec. 16, floodwater spilled through a double-stacked wall of flood barriers lining the White River through the City of Pacific. This required evacuation of more than 200 homes for safety. We and other emergency responders have been working to reinforce the flood barriers and make improvements to reduce the chance of future breaches.
Flood conditions have held steady on the Cedar and Green rivers, with each river forecast to hold at flood phase 3. Our Flood Patrol crews are still actively monitoring conditions on the White, Cedar, and Green rivers and will be receiving additional support from 10 National Guard members.

Dec. 17, 2025 – 4:15 a.m. update
King County Flood Warning Center: Cedar River reaches Phase 4 flood alert level
The Cedar River has reached the Phase 4 flood alert level from controlled releases at Landsburg Dam east of Renton.
As of 4 a.m. Wednesday, Dec. 17, flows at Landsburg Dam were recorded at 5,060 cubic feet per second, just higher than the Phase 4 flood alert threshold of 5,000 CFS.
There is an extensive list of roads that could be affected by floodwaters when the Cedar River reaches this flood level, including several roads that are the sole access to neighborhoods where residents could become trapped by rising waters. Be sure to check the King County My Commute website for the latest information on road closures.
Elsewhere in King County, the Snoqualmie, Green, and White rivers all remain at Phase 3 flood alert levels, with some flooded roads possible along these rivers, too.
You can track current river levels at kingcounty.gov/flood, and visit kcemergency.com for urgent updates and resources.
Dec. 17, 2025 – 2:15 a.m. update
The Green River has reached Phase 3 flood alert level from controlled releases at Howard Hanson Dam in the Cascade foothills.
Dam managers say releases from the dam help create additional flood storage capacity, and are expected to keep the river high – but stable – for several days.
Meanwhile, the Snoqualmie River remains at a Phase 3 flood alert with some road closures expected into Wednesday. Increased rainfall across eastern King County sent flows along the Snoqualmie River higher.
At 2:15 a.m. on Wednesday, the sum of the Snoqualmie River’s three forks registered at 22,830 cubic feet per second (CFS) – comfortably past the Phase 3 flood alert threshold of 20,000 CFS, and slowly climbing.
Forecasts call for a steady decrease in the Snoqualmie’s flows once Wednesday’s elevated river levels subside. Until that happens, we could see flooding of varied depths across the Snoqualmie Valley, and numerous road closures are likely. Be sure to check the King County My Commute website for the latest information.
Elsewhere, the White River has been holding steady at a Phase 3 flood alert with controlled releases from Mud Mountain Dam expected to keep river levels elevated for several days.
Finally, the Cedar River has been holding steady at a Phase 3 moderate flood flow and was steadily dropping toward minor flood levels.
You can track current river levels at kingcounty.gov/flood, and visit kcemergency.com for urgent updates and resources.
Dec. 16, 2025, 10 p.m.
Additional rainfall across the Cascade foothills has pushed flows in the upper Snoqualmie River to minor flood levels, with the potential for brief impacts to roads and low-lying areas overnight Dec. 16 and early in the day on Dec. 17.
If rainfall intensifies, the Snoqualmie River could rise up to a moderate flood level early by tomorrow morning, with additional flood impacts along the river Wednesday. Widespread flooding is not expected because of this current storm, and river forecasts call for a steady decrease in river levels once Wednesday’s elevated flows subside.
Elsewhere tonight, flows remain high on the Cedar, Green and White rivers because of planned releases from upstream dams. As of 9 p.m. Tuesday, the Cedar River at Landsburg was at a Phase 3 moderate flood flow and was steadily dropping toward minor flood levels.
On the Green River, planned releases from Howard Hanson Dam are expected to hover right around the Phase 3 flood alert level for several days, as managers release water to create more flood storage capacity behind the dam.
Finally, the White River has also dropped into a Phase 3 flood alert level after a long stretch of higher river flows from planned releases out of Mud Mountain Dam southeast of Enumclaw.
As with Howard Hanson Dam on the Green River, Mud Mountain Dam is expected to maintain carefully managed but elevated releases from the dam so there’s enough capacity to store flows in the upper White River watershed for the next storm.
You can track current river levels at kingcounty.gov/flood, and visit kcemergency.com for urgent updates and resources.
Dec. 15, 2025, 8:59 p.m.
Emergency repairs were made this afternoon to a small breach in the Desimone Levee along the Green River in Tukwila. A full week of high flows can saturate levees and leave them weak and susceptible to leaking and other actions. As of this evening, the levee is stabilized from emergency work.
King County is working closely with cities and partners to respond to urgent situations like this levee breach. King County Flood Patrol staff continue monitoring conditions in river basins across the county, having made several emergency repairs on the Green and Cedar rivers and monitoring HESCO flood barriers on the White River.
Additional rain last night and into the morning briefly pushed the South Fork Skykomish River back to Flood Phase 2 and the Snoqualmie River has returned Flood Phase 2 as well. The Cedar and Green rivers have held steady at Phase 3, while the White River remained at Phase 4.
High river levels are likely to continue on the Green, and White rivers for several days as flood control dams in the upper watersheds continue to slowly release stored floodwaters. Residents should stay alert, track changing conditions, and follow official guidance to stay safe.
Track current river levels at kingcounty.gov/flood and visit kcemergency.com for urgent updates and resources. Stay ready and be vigilant.
Flood risks remain – stay alert and follow safety reminders
Dec. 14, 2025, 8:37 a.m.
Flood fighting continues in King County. While many rivers are receding, the Cedar, Green, and White rivers remain at severe and moderate flood phases. Rivers are expected to rise again from late Monday into Tuesday as rain returns to our area. This could cause flooding in urban areas and on small streams and rivers.
The King County Flood Warning Center is open, and Flood Patrols are operating continuously into next week to monitor and respond to conditions on the ground. If you have questions or information to share about flooding near you, please call the Flood Warning Center at 206-296-8200 or 1-800-945-9263.
Safety reminders
- If you are in immediate danger, call 911.
- Stay away from landslides and downed power lines.
- Road safety: Heavy rainfall and flooding have affected many roads and bridges across the county. Before you travel, check for updates:
- MyCommute: Road closures and restrictions in unincorporated King County
- WSDOT: Real-time travel across the region
- Metro and Sound Transit service impacts
- Stay healthy: Rainfall and flooding have caused sewage overflows in many areas across King County. Please avoid touching all surface water (including lakes, ponds, streams, rivers, and Puget Sound) at this time.
Returning to your home or business
- Never turn power on or off yourself while standing in water.
- Do not turn gas back on if your natural gas has been shut off at the meter. Call PSE to schedule a technician to inspect the natural gas piping and relight appliances.
- Open windows and doors and pump out water after flood waters recede. Mold can grow within 24-48 hours after a flood, which can cause health risks.
- When cleaning up, wear rubber gloves and boots, a mask, eye protection, long-sleeved shirts and long pants.
- If you have a flooded private water system or well, only use bottled, boiled, or treated water. If you boil your water, make sure it remains at a rolling boil for at least one minute. Then it is safe to drink.
- If you have a flooded septic system, do not use your septic system, and disinfect it after the flood. When flooding subsides, call a maintainer to check that the flooding did not damage your septic system. See a list of maintainers.
- Always wash your hands with soap before eating.

King County Flood Warning Center opens as the Snoqualmie River reaches Phase 2 with widespread flooding in the forecast
Dec. 8, 2025, 5 p.m.
King County’s Flood Warning Center opened at 4:35 p.m. on Monday, Dec. 8, to track flooding along the Snoqualmie river. A strong atmospheric river has brought moderate to heavy rainfall causing rivers across the region to rise.
As of 4:51 p.m. on Monday, Dec. 8, the sum of the Snoqualmie River’s three forks gauge was recorded at 12,710 cubic feet per second (CFS) – that’s slightly higher than the Phase 2 flood alert threshold of 12,000 CFS. At these flows, minor flooding could occur in low-lying areas along the river.
An atmospheric river is like a “river in the sky” that transports water vapor outside of the tropics. This atmospheric river is reported to be nearly 7,000 miles long, about three times longer than the average atmospheric river. Weather forecasts predict that our local rivers will continue to rise and more flooding across the region is expected.
King County Flood Warning Center employees are monitoring stream gauges and weather reports to provide updated information on river conditions as necessary. Real-time river level information is available online at kingcounty.gov/flood.
The Flood Warning Center is staffed twenty-four hours a day, seven days a week during flood events. The center serves as an information clearinghouse for the public and other agencies responsible for ensuring public safety during a flood event. Call the Flood Warning Center during an activation at 206-296-8200 or 1-800-945-9263 to ask questions about current flood conditions. There’s also a recorded message center with continuous updates of river gauge readings, flood phases, and other related information.
King County offers free KC Flood Alerts, an automated system with customized flood alerts on King County major river systems. When you sign up for KC Flood Alerts, you’ll get immediate notifications about pending high water via email, text or voicemail. This gives subscribers the maximum amount of warning about potential flooding.
Free sandbag materials are also available to the public. Sandbags can reduce damage from flooding when used correctly. Remember these tips if you need to use them during a flood:
- Give yourself enough time, sandbags take time to fill.
- Work in a team of three people and fill the bags halfway full.
- Stack them in a pyramid shape with overlapping seams to prevent water from getting through. Sandbags are only effective if placed correctly.
Find out which sandbag distribution location is nearest you and watch a video about how to use sandbags effectively at kingcounty.gov/sandbags. The North Bend sandbag distribution site at North Bend City Public Works (1155 E North Bend Way, North Bend WA 98045) will remain open over the night of Dec. 8 for people who need materials.
We’ll provide updated information on flood conditions throughout the duration of this flood event – be sure to check back frequently for the latest details.
