I took a peek at the seas from the beach and with the short reach and WNW direction of travel the waves coming ashore are not that bad as far as something that might damage the pier. The waves are not very organized - really choppy. That may change in a few hours when the south wind hits, but I hope not.
I may be wrong, but I think the pier should be fine.
Edit: 8:00 pm - Ouch. Winds are dropping, but moving to the south. Wave heights are still building and the surge is increasing at Perdido Pass.
