Weather.com claims a 15 to 20 foot storm surge possible.
Now imagine that, I can't imagine that at my boat slip. I am in Seaford Va, lower Chesapeake bay. I can not even contemplate what 10 foot more of water would do here.
If you hauled out, imagine what 15 to 20 foot of surge would do to boats up on stands at your marina. Where I am the parking lot actually goes under water at very high normal tides. Seaford is very low land area.
High tide that I saw was unusually high today at my slip, a few inches below the finger pier. neighbors pier was covered in sea grass, which means it went under water.
My prep, I tied my bimini top shut. And added a large fender to the finger pier.
Anyone ever ride out a hurricane on the boat? I did that for a cat 1 over 10 yrs ago. Was not a bad experience. The eye came right over us, so calm, then the winds reversed. that was at the Salt Ponds in Hampton Va. Huge breaking waves were visible at the inlet. We had some white water in the harbor.
