Darrol Haug from Edmonds measures the height of the water to the top of the seawall on the Edmonds waterfront during a very high tide on December 28, 2022. Haug is concerned about global warming and the Army Corps of Engineers' estimate that he thinks says the water could rise somewhere around two feet to four feet by 2040 or something like that. Haug estimates that the seawall will not hold back the rising tides if their estimates are correct and logs, debris, and water could come over. A coastal flood warning remains in effect in the Puget Sound region. Significant coastal flooding is expected until 1 p.m. Wednesday, according to the National Weather Service.
