The minimal storm surge from Hurricane Hugo grounded a ferry in Fajardo, illustrating the storm's impact despite estimates of only 500,000 cubic meters of sand washing ashore along the Piñones shoreline. Understanding terminology such as storm surge, storm tide, and high water levels is essential for grasping the dynamics of hurricanes. This introduction explores how storm physical characteristics and coast shape influence water levels during storms. A profile of storm surge levels along the South Carolina coast complements the significance of Hurricane Hugo's impact.

Storm surge from Hurricane Hugo was minimal, but enough to ground this ferry in Fajardo.
Sand washover along the Piones shoreline after Hurricane Hugo. An estimated 500,000 cubic meters of sand was washed ashore along this stretch (Bush, 1991).
Terminology • Storm surge—water above normal astronomical tide • High water level—maximum still water height reached during storm • Storm tide—NOAA term for high water level
Storm Surge • Storm physical characteristics • Movement of the storm • Shape of the shoreline
