Hurricane Katrina was a major tropical cyclone that was the cause of catastrophic damage in the southeastern United States and will likely become the worst natural disaster ever to hit the United States with major global economic consequences caused by the severe disruption of oil supplies, exports, and imports.
Disaster relief plans are in operation in the affected communities. Some experts predict one million people could become homeless as a result of the storm. Currently five million people are without power in the Gulf Coast, and it may be two months before all power is restored.
Katrina is the deadliest hurricane in the United States of America since at least 1969, when Hurricane Camille killed at least 256 people, left tens of thousands homeless and may become the deadliest named hurricane in the U.S. on record (surpassing Hurricane Audrey in 1957, which killed at least 390, with up to 160 never accounted for). The deadliest hurricane in U.S. history (by far) is the Galveston Hurricane of 1900, which killed around 8,000 (possibly up to 12,000) people. The death estimates of Katrina so far are "in the thousands", stated by the New Orleans mayor Ray Nagin on August 31, but it will take weeks before accurate numbers are known. Katrina is also expected to be the costliest natural disaster in United States history.
