Several major hurricanes have caused catastrophic damage along the Gulf Coast throughout history. Notable examples include:

  • Galveston hurricane of 1900: Striking Texas as a category 4 storm, this remains the deadliest natural disaster in U.S. history, claiming at least 8,000 lives and devastating the low-lying port city.123
  • Hurricane Katrina: In 2005, this storm caused massive destruction across Louisiana, Mississippi, and Alabama. It is recognized as the costliest natural disaster in U.S. history, with severe flooding in New Orleans caused by the failure of the levee system.423
  • Hurricane Harvey: This 2017 storm was uniquely destructive due to its slow movement, which resulted in record-breaking rainfall and catastrophic flooding in the Houston area.5
  • Hurricane Helene: Making landfall in Florida’s Big Bend region in 2024 as a category 4 hurricane, Helene caused widespread damage and loss of life across multiple states due to extreme storm surge and inland flooding.6

These storms highlight the vulnerability of the Gulf Coast to intense tropical cyclones, which are often fueled by the warm waters of the Gulf of Mexico.14562
