All of the shoreline areas of Puget Sound are under a Tsunami Advisory in anticipation of some impact from the massive overnight earthquake in Chile.
The National Weather Service put out the advisory on Saturday morning for the entire Washington Coast, the Strait of Juan de Fuca, all of the San Juan Islands and all the inland waters in and around Puget Sound and Hood Canal.
The West Coast Tsunami Warning Center in Palmer, Alaska estimates that the waves will enter Puget Sound just after 4 p.m. and get to Seattle around 4:41 p.m. The waves will continue to come into the sound for a few hours after that, with the strongest waves coming about two hours after the first waves come in.
The main issues will not be the waves themselves, as they will likely be not even a foot above normal on average. But the concern is for the currents that will get much stronger than normal, especially as they wash up onto shore. There is also a worry about surges in bays, inlets and harbors along the sound.
So be careful when you're near the water today. Or just watch from a safe distance.
