Hurricane Katrina
Category 5 Atlantic hurricane in 2005
Hurricane Katrina was an extremely powerful and catastrophic tropical cyclone that affected the Southeastern United States in late August 2005, particularly in and around the city of New Orleans. Katrina became the United States' costliest tropical cyclone, with an estimated $125 billion in damages. The hurricane killed 1,392 people, making it the deadliest American hurricane since the 1928 Okeechobee hurricane. Katrina was the twelfth tropical cyclone, the fifth hurricane, the third major hurricane, and the second Category 5 hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, as measured by barometric pressure.
This brief starts where responsible research should: with the source description of “Hurricane Katrina” as category 5 Atlantic hurricane in 2005. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as category 5 Atlantic hurricane in 2005. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 23, 2026. The first chronological checks are 2005 and 1928.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
