A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at5.shtml?ripCurrents

Storm surge. The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…

Cape Lookout to Duck, North Carolina…2 to 4 ft

The deepest water will occur along the immediate coast where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
