Does anyone have any data indicating what would happen if the Bluffton area took a direct hit from a large hurricane? How far inland would the water come? Could storm surge make it all the way to I-95?
TIA

Here's an interactive map by the National Hurricane Center that has projections of how far the storm surge could go. It does not look good for the Bluffton area. https://experience.arcgis.com/experi...ge/Category-5/

Actually that shows a 9 foot storm surge. That would be a heckuva storm.

That site is the official source for the answer to your question from NOAA/NHC. There are tabs at the top to change category of hurricane from 1 to 5. These maps are considered accurate down to the 'neighborhood' street level. Best viewed on pc/tablet, if on mobile turn phone sideways so can hide the menu bar that otherwise blocks the map. This doesn't mean all those areas flood if a storm came, just at each point what could the water realistically reach given the right circumstances (ie: angle of approach of storm, at certain movement speed, at certain wind speed, at high tide, etc, etc).

That region and down into Georgia is extremely flat with overall coastline shape helping create a bowl like shape as well. In general, likely greatest surge flooding impact would be a storm coming perpendicular into the coast, with worst surge on the North side of that. But typically storms nearing here are in process of re-curving up so typically don't receive direct hit as much as say S FL or Eastern NC do. Per NHC statistics that area see a Cat1 or 2 Hurricane eye/center *on average* within 57miles every 9 or 10yrs, and Cat3 or higher about every 35yrs. Water can flood to i95 in some areas of the region (Ref that map link) and insurance rates likely reflect this as well.
