Hazards and Resilience and Climate Change

King tides return to Washington shores

December 12, 2024

The highest tides of the year return to Washington state this weekend, with areas like Shelton and Olympia expecting high tides over 16 feet.

King tides, extreme-high tides that occur when Earth experiences increased gravitational pull from the moon and sun, are an annual yet dramatic feature of Washington winters. Alone, they can cause flooding conditions in low-lying areas. Combined with other factors–like high winds and wave action, especially during coastal storms–flooding can become more ...

Federal funding will build capacity in Washington coastal Tribes and communities to address hazards due to climate change

August 22, 2024

Coastal Tribes and communities in Washington are on the front lines of climate change. Many are already grappling with associated coastal hazards, including sea level rise and flooding. However, all too often, these communities lack the capacity to adequately address the increasing climate risks that they face. 

Washington Sea Grant (WSG) and the Climate Impacts Group (CIG) — both based at the University of Washington College of the Environment — collectively received $8.1 million in ...

New modeling tool shows impacts of sea level rise, coastal flooding to Whatcom County

February 27, 2024

Created by the United States Geological Survey (USGS) and supported by Washington Sea Grant, the Coastal Storm Modeling System (CoSMoS) will soon be available for use across Washington state

From rising seas to eroding shorelines and more frequent, intense storms, the hazards faced by coastal communities are only projected to grow. Recognizing these threats, planners and managers around Washington are assessing the vulnerability of their communities and planning for impacts – in particular, the impacts ...

Drone videos show height of tsunami based on UW modeling

An evacuation route in Westport, Washington gets a “tsunami eye” view

October 20, 2022

It started with a question: How can emergency managers and educators make tsunami evacuation maps and routes easier to remember for coastal communities?

That’s when Washington Sea Grant Coastal Hazards Specialist Carrie Garrison-Laney came up with an idea.

“Some people are visual in terms of how they understand things,” she said.

“Being able to see video of how high a tsunami could be on a familiar landscape is a ...

Monitoring the Damage in the Heat Wave’s Wake

From the Autumn 2022 Sea Star

Washington Sea Grant rapidly provided funding to two projects to survey the impacts of the historic June 2021 heat wave on intertidal marine life

By Samantha Larson, WSG Science Writer

In June 2021, the peak of an unprecedented heat wave coincided with extremely low tides in the Salish Sea, wreaking havoc on intertidal ecosystems. As a “heat dome” settled above the Pacific Northwest for several days and the temperatures climbed well above 100 degrees Fahrenheit, many ...

Sea Levels are Rising in Washington. What will the Shorelines of the Future be like?

July 22, 2022

A new report from the Washington Coastal Resilience Project evaluates the trade-offs between various strategies to manage the impacts of sea level rise

As sea levels continue to rise, coastal hazards such as flooding and erosion will become increasingly common. According to recent assessments, over 14,000 homes and structures in Washington State — representing a current value of over 8 billion dollars ...

How can we better prepare for natural hazards on our coasts? Inter-organizational collaboration to assist local efforts may be key

March 24, 2022

A newly completed project lays the foundation for a team to help Washington’s coastal communities be better prepared for floods, erosion and other coastal hazards

Floods. Erosion. Sea level rise. Tsunamis. All of these hazards threaten Washington State’s coasts — with potentially dire consequences. Although there have been many efforts and investments to respond to disaster events, geographically isolated communities on the state’s Pacific coast often lack sufficient capacity to undertake comprehensive planning efforts to ...

New story map unites sea gardens around the Pacific and shows the importance of revitalizing Indigenous mariculture practices for food sovereignty and resilience

February 17, 2022

See the interactive, “living” story map at www.seagardens.net

Indigenous People have been stewarding the ocean for thousands of years. This stewardship has appeared in many different forms around the world, all of which represent a reciprocal relationship between humans and the sea rooted in deep place-based knowledge. From octopus houses in Haida Gwaii to fish ponds in Hawaiʻi, an Indigenous mariculture renaissance is making waves as groups across the Pacific seek to ...

Impacts from the Summer 2021 Heatwave on Washington Shellfish

July 21, 2021

The record-breaking heat that hit the Pacific Northwest from June 23 to 28, 2021, caused harm to many intertidal shellfish and invertebrate species on Washington beaches.

On many beaches, species such as cockles, varnish clams, butter clams, and native littleneck clams—normally buried out of sight—popped to the surface of the substrate in large numbers. Manila clams were also impacted in some areas. Surfaced clams were observed to be gaping, a sign of stress, or had already died from the ...
