Tropical Depression 13 was the thirteenth and deadliest tropical cyclone in the 2013 Atlantic hurricane season. The system was infamous for its mass destruction and fatalities it caused. A grand total of 347 fatalities were reported throughout Louisiana and Mississippi. It also flooded major sections of the New Orlans parish from a severe storm surge although a 5.8 magnitude earthquake over the southeastern Gulf of Mexico was partially responsible for the catastrophic damages.
