Re: [Paddlewise] Seiche

    This sounds like a description of what happens in Back Bay at Virginia Beach. We
were told the winds had blown all of the water out of the north part of the bay  a
week or so before we arrived and that only a couple of days before we got there the
wind had changed and blown it back in.
    We didn't test it but I'd guess this is a very shallow bay. It is totally non
tidal because it is 70 miles in from the mouth of the bay so all the movement is
wind induced. I'm kind of glad we didn't know about this being a possiblity or it
would have given me one more thing to worry about for our vacation. We lucked out.
The winds were quite strong the first day. 15+ k from the s,se. The next day as
totally calm. When we ran into the flies I found myself wishing the wind back.
