Storm Surge/Tide — Jackson, Mississippi

2005-08-29 · Jackson, Mississippi

Wider weather episode

Storm surge damage across coastal Mississippi was catastrophic and approached or exceeded the surge associated with Hurricane Camille and impacted a much more extensive area. Almost total destruction was observed along the immediate coast in Hancock and Harrison Counties with storm surge damage extending north along bays and bayous to Interstate Highway 10 in some instances. Thousands of homes and businesses were destroyed by the storm surge. Most tide gages were destroyed by the storm surge so storm surge was determined primarily by post storm high water mark surveys conducted by FEMA. An estimated storm surge of approximately 23.0 feet occurred at the Hancock County EOC operations area in Waveland, and the high water mark measured on the Jackson County EOC building in Pascagoula was 16.1 feet. Preliminary estimates of storm surge along the Mississippi Coast include Hancock County 19-25 ft, Harrison County 19-25 feet, Jackson County 17-21 ft. Wave action on top of the storm surge enhanced the damage in many area. All storm surge heights are still water elevations referenced to NAVD88 datum.
