“On 18 August, Hurricane Camille made landfall on Mississippi between Bay St. Louis and Pass Christian as an incredibly powerful hurricane. The precise wind speed at landfall will never be known because all measuring instruments were destroyed during the hurricane’s impact (it is estimated that gusts reached 322 km/h [200 mph]). Electricity also went out as the storm approached.
As Hurricane Camille came ashore, it caused a great amount of destruction. A 7.5 m (24.6 ft) storm surge inundated 860,000 acres of land in Louisiana and overtopped seawalls along the Mississippi shore, pushing water three to four blocks inland along the state’s entire coast. U.S. Highway 90, which runs along the shore, flooded as the storm surge crested seawalls and was badly broken and covered in much debris. The barrier islands along the Gulf Coast were badly damaged. The storm surge inundated 70% of Dauphin Island, a 22.5 km (14 mi) long island along the Alabama coast. A combination of strong winds and rain split Ship Island, off the coast of Mississippi, into two separate islands.”
