Hurricane Katrina <=SEP=> Hurricane Katrina was the costliest natural disaster and one of the five deadliest hurricanes in the history of the United States . The storm is currently ranked as the third most intense United States landfalling tropical cyclone , behind only the 1935 Labor Day hurricane and Hurricane Camille in 1969 . Overall , at least 1,245 people died in the hurricane and subsequent floods , making it the deadliest United States hurricane since the 1928 Okeechobee hurricane . Total property damage was estimated at $ 108 billion ( 2005 USD ) , roughly four times the damage wrought by Hurricane Andrew in 1992 in the United States .   The eleventh named storm and fifth hurricane of the 2005 Atlantic hurricane season , Katrina originated over the Bahamas on August 23 from the interaction between a tropical wave and the remnants of Tropical Depression Ten . Early the following day , the new depression intensified into Tropical Storm Katrina . The cyclone headed generally westward toward Florida and strengthened into a hurricane only two hours before making landfall at Hallandale Beach and Aventura on August 25 . After very briefly weakening to a tropical storm , Katrina emerged into the Gulf of Mexico on August 26 and began to rapidly deepen . The storm strengthened to a Category 5 hurricane over the warm waters of the Gulf of Mexico , but weakened before making its second landfall as a Category 3 hurricane on August 29 in southeast Louisiana .   The storm caused severe destruction along the Gulf coast from central Florida to Texas , much of it due to the storm surge and levee failure . Severe property damage occurred in coastal areas , such as Mississippi beachfront towns ; over 90 percent of these were flooded . Boats and casino barges rammed buildings , pushing cars and houses inland ; water reached 6 - from the beach .   Over fifty breaches in New Orleans 's hurricane surge protection were the cause of the majority of the death and destruction during Katrina on August 29 , 2005 . Eventually 80 % of the city and large tracts of neighboring parishes became flooded , and the floodwaters lingered for weeks . According to a modeling exercise conducted by the U.S. Army Corps of Engineers ( USACE ) , two-thirds of the deaths in Greater New Orleans were due to levee and floodwall failure . All of the major studies concluded that the USACE , the designers and builders of the levee system as mandated by the Flood Control Act of 1965 , is responsible . This is mainly due to a decision to use shorter steel sheet pilings in an effort to save money . In January 2008 , Judge Stanwood Duval , U.S. District Court , ruled that despite the Corps ' role in the flooding , the agency could not be held financially liable because of sovereign immunity in the Flood Control Act of 1928 . Exactly ten years after Katrina , J. David Rogers , lead author of a new report in the official journal of the World Water Council concluded that the flooding during Katrina `` could have been prevented had the corps retained an external review board to double-check its flood-wall designs . ''   There was also an investigation of the responses from federal , state and local governments , resulting in the resignation of Federal Emergency Management Agency ( FEMA ) director Michael D. Brown , and of New Orleans Police Department ( NOPD ) Superintendent Eddie Compass . Many other government officials were criticized for their responses , especially New Orleans Mayor Ray Nagin , Louisiana Governor Kathleen Blanco , and President George W. Bush . Several agencies including the United States Coast Guard ( USCG ) , National Hurricane Center ( NHC ) , and National Weather Service ( NWS ) were commended for their actions . They provided accurate hurricane weather tracking forecasts with sufficient lead time .

Florida <=SEP=> Florida -LSB- ˈflɒrᵻdə -RSB- ( Spanish for `` land of flowers '' ) is a state located in the southeastern region of the United States . It is bordered to the west by the Gulf of Mexico , to the north by Alabama and Georgia , to the east by the Atlantic Ocean , and to the south by the Straits of Florida and Cuba . Florida is the 22nd-most extensive , the 3rd-most populous , and the 8th-most densely populated of the U.S. states . Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States . The Miami metropolitan area is Florida 's most populous urban area . The city of Tallahassee is the state capital .   A peninsula between the Gulf of Mexico , the Atlantic Ocean , and the Straits of Florida , it has the longest coastline in the contiguous United States , approximately 1350 mi , and is the only state that borders both the Gulf of Mexico and the Atlantic Ocean . Much of the state is at or near sea level and is characterized by sedimentary soil . The climate varies from subtropical in the north to tropical in the south . The American alligator , American crocodile , Florida panther , and manatee can be found in the Everglades National Park .   Since the first European contact was made in 1513 by Spanish explorer Juan Ponce de León -- who named it La Florida ( -LSB- la floˈɾiða -RSB- `` land of flowers '' ) upon landing there in the Easter season , Pascua Florida -- Florida was a challenge for the European colonial powers before it gained statehood in the United States in 1845 . It was a principal location of the Seminole Wars against the Native Americans , and racial segregation after the American Civil War .   Today , Florida is distinctive for its large Cuban expatriate community and high population growth , as well as for its increasing environmental issues . The state 's economy relies mainly on tourism , agriculture , and transportation , which developed in the late 19th century . Florida is also renowned for amusement parks , orange crops , the Kennedy Space Center , and as a popular destination for retirees .   Florida culture is a reflection of influences and multiple inheritance ; Native American , European American , Hispanic and Latino , and African American heritages can be found in the architecture and cuisine . Florida has attracted many writers such as Marjorie Kinnan Rawlings , Ernest Hemingway and Tennessee Williams , and continues to attract celebrities and athletes . It is internationally known for golf , tennis , auto racing and water sports .

Atlantic hurricane <=SEP=> An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean , usually in the summer or fall . A hurricane differs from a cyclone or typhoon only on the basis of location . A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean , a typhoon occurs in the northwestern Pacific Ocean , and a cyclone occurs in the south Pacific or Indian Ocean .   Tropical cyclones can be categorized by intensity . Tropical storms have one-minute maximum sustained winds of at least 39 mph ( 34 knots , 17 m/s , 63 km/h ) , while hurricanes have one-minute maximum sustained winds exceeding 74 mph ( 64 knots , 33 m/s , 119 km/h ) . Most North Atlantic tropical storms and hurricanes form between June 1 and November 30 . The United States National Hurricane Center monitors the basin and issues reports , watches , and warnings about tropical weather systems for the North Atlantic Basin as one of the Regional Specialized Meteorological Centers for tropical cyclones , as defined by the World Meteorological Organization .   In recent times , tropical disturbances that reach tropical storm intensity are named from a predetermined list . Hurricanes that result in significant damage or casualties may have their names retired from the list at the request of the affected nations in order to prevent confusion should a subsequent storm be given the same name . On average , in the North Atlantic basin ( from 1966 to 2009 ) 11.3 named storms occur each season , with an average of 6.2 becoming hurricanes and 2.3 becoming major hurricanes ( Category 3 or greater ) . The climatological peak of activity is around September 11 each season .   In March 2004 , Catarina was the first hurricane-intensity tropical cyclone ever recorded in the Southern Atlantic Ocean . Since 2011 , the Brazilian Navy Hydrographic Center has started to use the same scale of the North Atlantic Ocean for tropical cyclones in the South Atlantic Ocean and assign names to those which reach 35 kn .
