In August 2016, prolonged rainfall from an unpredictable storm resulted in catastrophic flooding in the state of Louisiana, United States; thousands of houses and businesses were submerged. Louisiana's governor, John Bel Edwards, called the disaster a "historic, unprecedented flooding event" and declared a state of emergency. Many rivers and waterways, particularly the Amite and Comite rivers, reached record levels, and rainfall exceeded 20 inches (510 mm) in multiple parishes.
