Central Louisiana is facing catastrophic flooding after the remnants of Tropical Storm Arthur dumped nearly two feet of rain over 48 hours, triggering what local officials are calling a "1,000-year flood." The storm, the first named system of the 2026 Atlantic hurricane season, made landfall near Matagorda, Texas, on June 18, 2026, before weakening and stalling over the central Gulf Coast. Avoyelles Parish, about 70 miles northwest of Baton Rouge, has been hardest hit, with up to 20 inches of rain swelling Bayou Rouge and other tributaries, inundating non-flood-zone communities and prompting amphibious rescues of dozens of residents and pets.
