Seattle, WA – The National Weather Service (NWS) has issued urgent alerts for coastal flooding and dangerously high surf along the northern Washington coast, with conditions expected to worsen from Wednesday morning through Thursday night. Waves reaching up to 25 feet and rising water levels could lead to flooding, road closures, and hazardous beach conditions.
The Incident: Coastal Flooding and High Surf Threat
The NWS Seattle office announced a Coastal Flood Warning in effect from 7 a.m. Wednesday to 10 p.m. Thursday, warning that water levels could rise 2 to 3 feet above ground level in low-lying coastal zones. In addition, a High Surf Advisory will remain in effect from 4 a.m. to 7 p.m. Thursday, with waves expected to reach 20 to 25 feet.
Officials say that these conditions will make many areas unsafe for travel or outdoor activity, particularly during high tide. Westport, La Push, and Grays Harbor County are expected to face the most significant flooding and storm surge impacts.
“The combination of high surf and elevated tides may cause widespread flooding of roads, beaches, and nearby structures,” NWS forecasters cautioned.
Investigation and Forecast Details
Meteorologists explain that the extreme wave activity is being driven by a strong Pacific storm system moving inland. The system’s onshore winds and low atmospheric pressure are expected to create storm surge conditions, pushing seawater into coastal zones and river mouths.
Peak flooding and surf impacts are forecast to occur on Thursday afternoon, when high tide coincides with strong wind gusts. This could cause erosion, inundation of homes, and dangerous debris movement along the shoreline.
The Grays Harbor Emergency Management Department warned that some areas could see water levels comparable to—or even higher than—earlier floods reported this week.
Preparedness Measures and Official Guidance
Emergency officials urge residents in vulnerable areas to prepare now and avoid coastal zones until the warnings expire.
Key safety recommendations include:
- Move vehicles and valuables away from flood-prone areas.
- Avoid walking or driving through floodwaters, as just a few inches of moving water can sweep away a car.
- Stay off driftwood and rocks near the water’s edge — sneaker waves can appear suddenly and pull people into the ocean.
- Follow local evacuation alerts if issued.
“If you live in a low-lying coastal area, take action before water rises,” the NWS advised. “Floodwaters can arrive quickly and create life-threatening conditions.”
Statements and Community Reactions
Residents along the coast have expressed growing concern as tides continue to rise. Local authorities are coordinating with the U.S. Coast Guard and emergency response teams to monitor conditions and assist with evacuations if necessary.
“We’re expecting heavy surf and dangerous conditions across beaches,” said a Grays Harbor County emergency official. “We’re asking everyone to stay off the coast and let first responders do their work safely.”
Businesses in Westport and Ocean Shores have begun securing property, while local marinas are advising boat owners to reinforce moorings and avoid launching during the storm period.
Background Context: Recent Coastal Impacts
This week’s flooding alert follows a series of Pacific storms that have battered the Washington coast, causing beach erosion, power outages, and minor flooding in coastal communities. Experts say the current storm pattern could persist into the weekend, increasing the risk of repeated high surf events.
According to NWS records, waves reaching 20 to 25 feet are among the highest observed this season, with storm surges posing long-term challenges for coastal infrastructure and marine operations.
Ongoing Developments and Next Steps
The NWS Seattle will continue to update forecasts as the system develops. Officials emphasize that residents should monitor weather alerts through the NOAA Weather Radio, the NWS website, or local media broadcasts.
Flooding and hazardous surf conditions are expected to subside by Friday morning, though cleanup and recovery efforts could take days in the hardest-hit areas.
Conclusion
With the potential for moderate to major flooding and waves up to 25 feet, authorities across Washington’s coastline are urging residents to take precautions immediately. Coastal communities remain on high alert as emergency teams prepare for rising tides and dangerous surf expected to peak on Thursday.
