Featured Article Summary #222

Hurricane Camille was one of the strongest hurricanes to hit the United States, making landfall in southern Mississippi in August 1969. It reached Category 5 strength, with maximum sustained winds of at least 157 mph, and was the third named storm of the 1969 Atlantic season. Camille formed as a tropical depression south of Cuba, strengthened as it moved toward and over Cuba, and then became a Category 5 hurricane in the Gulf of Mexico before striking near Bay St. Louis, Mississippi. At landfall, it had peak winds of 175 mph and a minimum pressure of 900 millibars, and it caused widespread death and damage across the United States, killing at least 343 people and causing at least $1.42 billion in damage. In Cuba, the hurricane brought dangerous winds and flooding, and in Mississippi it produced a record storm surge at the time, flattening much of the coastline. After moving inland, Camille quickly weakened, but its heavy rainfall caused severe flooding in parts of the Appalachians, and the name “Camille” was later retired. Camille formed from a tropical wave that left West Africa near Dakar on August 5, 1969, then moved across the Atlantic and Caribbean without an obvious closed circulation until a tropical depression formed around 00:00 UTC on August 14, roughly halfway between Jamaica and the Cayman Islands. It rapidly intensified into a tropical storm and then a hurricane by August 15, reaching Category 5 strength late on August 16 with peak winds of 175 mph and record-low central pressures measured by reconnaissance flights. Camille struck western Cuba, crossed into the Gulf of Mexico, and later made landfall near Waveland, Mississippi, on August 18 with peak winds of 175 mph and a reanalyzed minimum pressure near 900 mb, before weakening quickly inland. It weakened to a tropical depression over Tennessee, then moved northeast across the eastern U.S., regained tropical storm strength after reaching the Atlantic near Norfolk, and eventually became an extratropical cyclone after interacting with colder, drier air and a cold front south of Newfoundland. Camille had an extremely low landfall pressure of 900 mb, estimated maximum sustained winds of about 175 mph, and was one of only four Category 5 Atlantic hurricanes to hit the continental United States at that strength. When it made landfall in Mississippi, it caused the highest storm surge in the U.S. at the time, with tides reaching about 24.6 ft in Pass Christian, later surpassed by Hurricane Katrina in 2005. After crossing inland, Camille also brought record tropical cyclone rainfall to central Virginia, with the highest observed total reaching 27 inches. In the 1960s, Atlantic hurricanes used four repeating lists of women’s names, and retired names were supposed to come back after about ten years. After the name Carla was retired in 1961 and later replaced by Carol (which had originally been retired in 1954), scientists asked in 1969 to permanently retire Carol, Edna, and Hazel because research papers about the storms were still in progress. The committee agreed and needed another “C” name, and Banner Miller suggested Camille, after the daughter of an NHC worker—later noting that the choice was kept quiet for years. After Hurricane Camille formed, the National Hurricane Center warned people in the Isle of Pines and western Cuba to expect strong winds, heavy rain, and dangerous tides, leading officials to evacuate thousands to higher ground and move thousands of livestock to safety. In the United States, warnings and hurricane watches spread along parts of Florida, Mississippi, and Louisiana, prompting extensive preparations like securing buildings, moving ships to safer harbors, and evacuating about 200,000 people across Alabama, Mississippi, and Louisiana as shelters filled. Evacuation efforts sometimes faced confusion and disbelief about the storm’s severity, and some people chose not to leave. As the storm weakened inland, local weather offices still tried to monitor and warn communities about flooding, but limited radar, broken phone lines, and missing real-time rainfall data made alerts harder—so many warnings came through local police, volunteers, and river-gauge systems.
