Hurricane storm surge can reach multiple meters in height and be life-threatening to coastal areas and ground-floor facilities, potentially requiring relocation of vulnerable patients and assets to higher floors.

descriptive
Typical risks from storm surge associated with major hurricanes affecting coastal infrastructure and health facilities.
Very flat coastal delta terrain with land elevations in places less than 10 feet above the high-tide line is highly vulnerable to storm-driven ocean inundation because water can spread far inland.

temporal
Low-relief coastal deltas allow storm surge and floodwaters to propagate inland over large areas.
Coastal storms and storm surge can produce ocean overwash that floods and closes low-lying coastal roads and barrier-island highways and can undermine or collapse beachfront structures.
high
general
Overwash and surge occur when waves and elevated water levels transport water and sediment across normally dry land, damaging transportation routes and buildings.
