Lafourche Parish was the direct landfall point of Hurricane Ida in 2021, which made landfall at Port Fourchon as a Category 4 storm. The parish is one of the most geographically vulnerable in the US — its southern communities sit on disappearing barrier islands and coastal marshland that is subsiding into the Gulf of Mexico. Port Fourchon is a critical hub for offshore oil and gas operations.
