Katrina was the earliest 11th named storm on record before being surpassed by Tropical Storm Kyle on August 14, 2020. Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005, as the result of the merger of a tropical wave and the remnants of Tropical Depression Ten four days earlier.

Katrina was so catastrophic primarily because the very high storm surge overtopped the levee system in Orleans and St. Bernard parishes, leading to levee failures and breaches.

There were these barriers all around the City of New Orleans that were supposed to protect against flooding. But it had been so long since they had had a flood that many of the levies were in disrepair and they failed. So in a lot of ways, it was considered a preventable disaster.
