NOAA’s National Weather Service has released a coastal flood warning for southwest Washington. The warning will remain in effect from midnight 1/17/2018 to midnight 1/18/2017. Significant surf and beach erosion are expected.
Increasing Resiliency of Salmon and Steelhead using the Lower Columbia River by Enhancing Areas of Cold Water
By Catherine Corbett, Lower Columbia Estuary Partnership
The importance of cold water refuges to Pacific salmon and steelhead migrating through the Columbia River Basin recently has been well documented. Summertime water temperatures in the mainstem Columbia River have steadily increased over the last few decades, as has the length of these warm periods. Annual peak temperatures routinely exceed 21°C in most years and have been as high as 24°C. The warmest period typically occurs in July to early September, coincident with late-migrating summer Chinook and sockeye salmon and substantial portions of the fall Chinook salmon and summer steelhead runs. Water temperatures in the 19-22°C range are a significant concern because these temperatures can cause behavioral changes and a variety of sub-lethal effects on physiology, disease susceptibility, reproduction, and survival.

After a hot, dry summer, Washington communities were beset with a series of wildfires. Now Western Washington prepares for rain and catastrophic flooding. Along the coast, sea level continues to rise despite tectonic uplift while erosion changes the shoreline.
In recent years, NOAA has been hearing from coastal communities about their interest in being better prepared for coastal hazard impacts. We’re also noticing a growing recognition of the role that natural infrastructure (such as preserved open space) can play in helping to reduce risk to residents, businesses, and infrastructure. What communities might not know, is they can also take advantage of FEMA programs that provide insurance incentives and support adaptation planning and flood mitigation.
