Were there any mountains or hills around? It could have been a
mountain wave.


I don't think he had problems with mountains or hills at St Simons
Island,...it's a island off the coast of Georgia. A tool bridge away
from Brunswick , GA . Really flat land. Maybe winds coming ashore?

Here in NC you can get mountain waves a few hundred miles downwind from the
Appalachians, though I've never experienced anything as severe as the OP
describes. I think St Simons is too far south for Appalachian mountain waves,
though.
