A storm surge is an onshore gush of water associated with a low pressure weather system. Storm surges can cause beach accretion and erosion. [1] Historically notable storm surges occurred during the North Sea Flood of 1953, Hurricane Katrina, and the 1970 Bhola cyclone.
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves.
The more gradual the slope, the higher the storm surge. "The height of the storm surge is also dictated by the shape of the coast," Kottlowski said, citing differences between a concave coast ...
The storm surge caused substantial beach erosion, in some cases completely devastating coastal areas. In Dauphin Island (a barrier island ), approximately 90 mi (140 km) to the east of the point where the hurricane made landfall, the sand that comprised the island was transported across the island into the Mississippi Sound , pushing the island ...
Northeast Florida could get 3 to 5 feet of storm surge, the hurricane center projects. Storm surge is a serious concern with any major hurricane, which NOAA classifies as Category 3 or above. But ...
The largest surge occurred in the right-front quadrant of the hurricane in Mississippi. Though the total destruction of buildings and infrastructure in coastal communities made post-storm assessments of surge heights difficult, a maximum high water mark of 27.8 ft (8.5 m) was found in Pass Christian.

Storm surge at those levels is likely to cause flash flooding in areas including Cherry Grove in North Myrtle Beach, and the continued erosion of sand can leave nearby properties more vulnerable ...
Across much of western Alaska's coastline, the storm caused widespread erosion and coastal flooding from a combination of storm surge and waves estimated between 30 and 40 ft (9.1 and 12.2 m). [1] [7] [8] The most significant effects were felt in and around Nome where sea levels rose 8.73 ft (2.66 m) above normal, flooding low-lying areas. The ...
