The question is…did the Currents data provider (Copernicus) include the Puget Sound in their data?
Probably not (But this needs to be checked).
Therefore Windy cannot create this data and extend the visualization of the currents in this arm of the sea. In addition it is obvious that in narrow bays the prediction of currents is very difficult without taking into account precisely the seabed and the tides. It is therefore better to refer to the tide calculation itself.
