The green river levee flash flood warning remains a major public safety concern today as confirmed flooding continues along the Green River corridor in King County, Washington, following a levee failure that forced evacuations and disrupted daily life across several communities.
As of December 16, 2025, emergency officials confirm that water continues to pressure flood defenses near Tukwila, Kent, and Renton. Crews are actively reinforcing vulnerable areas while residents in designated zones remain under evacuation orders due to unstable river and ground conditions.

How the Flood Emergency Unfolded
Days of persistent, heavy rainfall caused the Green River to rise rapidly, pushing it beyond normal seasonal levels. The prolonged rain saturated surrounding soil, weakening flood protection systems designed to hold back high water.
Late Monday morning, a section of the Desimone Levee failed. Once the structure gave way, river water flowed into nearby low-lying neighborhoods and industrial areas. Emergency alerts were issued almost immediately, warning residents of fast-developing and dangerous conditions.
Officials described the flooding as sudden and severe, with limited time for response once the breach occurred.
Communities Affected by the Levee Failure
The flood impact has been concentrated in areas closest to the river and the damaged levee. The most affected locations include:
- Tukwila
- Renton
- Kent
- Nearby river-adjacent neighborhoods and industrial zones
At the peak of the emergency, tens of thousands of people were included in the warning area. As crews gained better visibility on water movement, the focus narrowed to residents and businesses closest to the breach.
Despite the adjustment, officials stress that flood risks remain serious for anyone near the river.
Evacuation Orders and Emergency Alerts
Authorities issued Level 3 evacuation orders, meaning residents were told to leave immediately without delay. These alerts were sent through emergency notification systems, mobile alerts, and local warning channels.
Residents were advised to:
- Move to higher ground as soon as possible
- Avoid floodwaters and riverbanks
- Leave the area if instructed by emergency officials
- Follow road closure and access restrictions
Emergency managers emphasized that ignoring evacuation orders could put lives at risk, as water levels can rise quickly with little notice.
Conditions at the Desimone Levee
The Desimone Levee was already under stress before the failure due to rising river levels and saturated ground. Emergency crews had attempted temporary reinforcement efforts, but continued rainfall reduced their effectiveness.
Once the levee failed, water pressure and erosion increased rapidly. Crews are now focused on stabilizing the area, monitoring seepage, and preventing further breaches.
While progress has been made, officials confirm that the levee remains vulnerable until water levels recede and permanent repairs can begin.
Emergency Response and State Support
Emergency response efforts escalated quickly after the levee failure. Multiple agencies coordinated to protect residents and infrastructure.
Response actions include:
- Sandbag placement and temporary barriers
- Traffic control near flooded corridors
- Assistance for evacuees and displaced workers
- Continuous monitoring of river levels
State resources were also deployed to support local crews, manage logistics, and assist with safety operations during the flood response.
Road Closures and Travel Disruptions
Floodwaters have forced closures of several major and secondary roadways, particularly near river crossings and industrial districts. Access to certain highways and surface streets has been restricted to prevent accidents and allow emergency operations.
Drivers are strongly urged to avoid flooded roads. Even shallow water can hide damage, debris, or strong currents capable of moving vehicles.
Officials continue to adjust traffic restrictions as conditions change.
Shelters and Assistance for Evacuees
Temporary shelters have been opened in nearby communities to provide safe housing for those displaced by flooding. These shelters offer space for families, individuals, and in some cases, pets.
Evacuees are encouraged to bring essential items, medications, and identification when possible. Emergency staff remain on-site to assist with basic needs and information.
Local authorities stress that shelters will remain open as long as evacuation orders stay in effect.
Ongoing Flood Risks and Monitoring
The green river levee flash flood warning remains active as officials continue to monitor rainfall patterns and river behavior. While some stabilization has occurred, the risk has not passed.
Additional rainfall could cause renewed pressure on flood defenses or expand flooded areas. Residents near the river are advised to stay alert and prepared to act quickly if conditions worsen.
Officials are providing frequent updates to ensure the public remains informed.
Why This Flood Event Is Significant
This flooding event highlights the challenges facing river communities during extended periods of heavy rain. Aging infrastructure, saturated soil, and rising water levels combine to increase flood risks.
Emergency managers note that early warnings and public cooperation are critical in preventing injuries and loss of life during such events.
The situation also underscores the importance of long-term flood planning and infrastructure maintenance.
What Residents Should Do Now
Officials continue to urge residents to take the situation seriously and follow guidance closely. Key steps include:
- Monitor emergency alerts and local advisories
- Avoid restricted or flooded areas
- Assist neighbors who may need help evacuating
- Do not return to evacuated areas until cleared
Emergency crews remain active around the clock, working to protect lives and property.
Looking Ahead
While immediate efforts focus on safety and stabilization, recovery planning will follow once water levels drop and conditions improve. Authorities stress that patience and cooperation will be essential during the coming days.
Residents are reminded that flood dangers can persist even after water recedes, including damaged roads and weakened ground.
Conditions along the Green River continue to evolve, so stay alert and share your thoughts or updates as this situation develops.
