3.2 Factors that intensify storm surges

Storm surges are pronounced:

  • over shallow water bodies
  • persistent strong winds
  • persistent low atmospheric pressure.

Resulting in coastal flooding that may impact many kilometers inland.

Storm surges are particularly pronounced:

  • in areas having a large tidal range
  • when occurring at high tide

Under such circumstances, the resulting surge is called a storm tide that includes the accumulative sea level elevation arising from the:

  • storm
  • tide
  • wave run-up
  • freshwater flooding.
