Early reports are that the water is washing up to the dunes in most areas, even Grayton. The one thing that will be interesting to watch is whether those waves will be strong enough to carve into the dunes substantially, or if they will be depositing sand from the front part of the beach to the toe of the dune. In storms like these, we often see a narrowing of the beach, but a slight build up of sand at the toe of the dune and the burying of a few boardwalk steps. My thoughts are that we will see both, with some slight "carving" occurring in eastern Walton County where the beach is narrower, and "redistribution" where the beach is wider. That's what happened the last time a big storm hit New Orleans.
