Hurricane Katrina was the costliest and one of the five deadliest hurricanes in the history of the United States.Knabb, Richard D; Rhome, Jamie R.; Brown, Daniel P (December 20, 2005; updated August 10, 2006). Tropical Cyclone Report: Hurricane Katrina: 23-30 August 2005 (PDF). National Hurricane Center. Retrieved on 2006-05-30. It was the sixth-strongest Atlantic hurricane ever recorded and the third-strongest hurricane on record that made landfall in the United States. Katrina formed on August 23 during the 2005 Atlantic hurricane season and caused devastation along much of the north-central Gulf Coast. The most severe loss of life and property damage occurred in New Orleans, Louisiana, which flooded as the levee system catastrophically failed, in many cases hours after the storm had moved inland. The hurricane caused severe destruction across the entire Mississippi coast and into Alabama, as far as 100 miles (160 km) from the storm\'s center. Katrina was the eleventh tropical storm, fifth hurricane, third major hurricane, and second Category 5 hurricane of the 2005 Atlantic season.
It formed over the Bahamas on August 23, 2005, and crossed southern Florida as a moderate Category 1 hurricane, causing some deaths and flooding there, before strengthening rapidly in the Gulf of Mexico and becoming one of the strongest hurricanes on record while at sea. The storm weakened before making its second and third landfalls as a Category 3 storm on the morning of August 29 in southeast Louisiana and at the Louisiana/Mississippi state line, respectively.
The storm surge caused severe damage along the Gulf Coast, devastating the Mississippi cities of Waveland, Bay St. Louis, Pass Christian, Long Beach, Gulfport, Biloxi, Ocean Springs, and Pascagoula. In Louisiana, the federal flood protection system in New Orleans failed in more than fifty places. Nearly every levee in metro New Orleans breached as Hurricane Katrina passed east of the city, subsequently flooding 80% of the city and many areas of neighboring parishes for weeks.Swenson, Dan D; Marshall, Bob (May 14, 2005). Flash Flood: Hurricane Katrina\'s Inundation of New Orleans, August 29, 2005 (SWF). Times-Picayune.
At least 1,836 people lost their lives in Hurricane Katrina and in the subsequent floods, making it the deadliest U.S. hurricane since the 1928 Okeechobee Hurricane. The storm is estimated to have been responsible for $81.2 billion (2005 U.S. dollars) in damage, making it the costliest natural disaster in U.S. history. The catastrophic failure of the flood protection in New Orleans prompted immediate review of the Army Corps of Engineers, which has, by congressional mandate, sole responsibility for design and construction of the flood protection. There was also widespread criticism of the federal, state and local governments\' reaction to the storm, which resulted in an investigation by the U.S. Congress, and the resignation of Federal Emergency Management Agency director Michael D. Brown. Conversely, the National Hurricane Center and National Weather Service were widely commended for accurate forecasts and abundant lead time.

Storm path
Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005 as the result of an interaction of a tropical wave and the remains of Tropical Depression Ten. The system was upgraded to tropical storm status on the morning of August 24 and at this point, the storm was given the name Katrina. The tropical storm continued to move towards Florida, and became a hurricane only two hours before it made landfall between Hallandale Beach and Aventura, Florida on the morning of August 25. The storm weakened over land, but it regained hurricane status about one hour after entering the Gulf of Mexico.
The storm rapidly intensified after entering the Gulf, partly because of the storm\'s movement over the warm waters of the Loop Current.Leben, Robert; Born, George; Scott, Jim. "CU-Boulder Researchers Chart Katrina\'s Growth In Gulf Of Mexico." University of Colorado at Boulder. September 15, 2005. Retrieved on 2006-06-05. On August 27, the storm reached Category 3 intensity on the Saffir-Simpson Hurricane Scale, becoming the third major hurricane of the season. An eyewall replacement cycle disrupted the intensification, but caused the storm to nearly double in size. Katrina again rapidly intensified, attaining Category 5 status on the morning of August 28 and reached its peak strength at 1:00 p.m. CDT that day, with maximum sustained winds of 175 mph (280 km/h) and a minimum central pressure of 902 mbar. The pressure measurement made Katrina the fourth most intense Atlantic hurricane on record at the time, only to be surpassed by Hurricanes Rita and Wilma later in the season; it was also the strongest hurricane ever recorded in the Gulf of Mexico at the time (a record also later broken by Rita).
Hurricane Katrina just after its third landfall, but still at hurricane status
Katrina made its second landfall at 6:10 a.m. CDT on August 29 as a Category 3 hurricane with sustained winds of 125 mph (205 km/h) near Buras-Triumph, Louisiana. At landfall, hurricane-force winds extended outward 120 miles (190 km) from the center and the storm\'s central pressure was 920 mbar. After moving over southeastern Louisiana and Breton Sound, it made its third landfall near the Louisiana/Mississippi border with 120 mph (195 km/h) sustained winds, still at Category 3 intensity.
Katrina maintained strength well into Mississippi, finally losing hurricane strength more than 150 miles (240 km) inland near Meridian, Mississippi. It was downgraded to a tropical depression near Clarksville, Tennessee, but its remnants were last distinguishable in the eastern Great Lakes region on August 31, when it was absorbed by a frontal boundary. The resulting extratropical storm moved rapidly to the northeast and affected eastern Canada.
Flanked by Michael Chertoff, Secretary of Homeland Security, left, and Secretary of Defense Donald Rumsfeld, President George W. Bush meets with members of the White House Task Force on Hurricane Katrina Recovery on August 31, 2005, in the Cabinet Room of the White House.
On the morning of August 26, at 10 a.m. CDT (1500 UTC), Katrina had strengthened to a Category 3 storm in the Gulf of Mexico. Later that afternoon, the NHC realized that Katrina had yet to make the turn toward the Florida Panhandle and ended up revising the predicted track of the storm from the panhandle to the Mississippi coast.Spann, James. "Models Shifting West," "NHC Shifting Track To MS Coast" and "Late Katrina Thoughts" from the ABC33/40 Weather Blog August 26, 2005. URL accessed July 23, 2006Stewart, Stacy (August 26, 2005). Hurricane Katrina Discussion No. 14, 5:00 p.m. EDT. National Hurricane Center. Retrieved on 2006-09-16. The NHC issued a hurricane watch for southeastern Louisiana, including the New Orleans area at 10 a.m. CDT August 27. That afternoon the NHC extended the watch to cover the Mississippi and Alabama coastlines as well as the Louisiana coast to Intracoastal City.

President George W. Bush declared a state of emergency in Louisiana, Alabama, and Mississippi two days before the hurricane made landfall.Bush, George W. "Statement on Federal Emergency Assistance for Louisiana." White House. August 27, 2005. Retrieved on 2006-06-05. (These declarations later proved to be a point of controversy; see below.) That same evening, the NHC upgraded the section of the hurricane watch from Morgan City, Louisiana to the Alabama-Florida border to a hurricane warning, 12 hours after it was issued, and also issued a tropical storm warning for the westernmost Florida Panhandle.
During video conferences involving the President on August 28 and 29, the director of the National Hurricane Center at the time, Max Mayfield, expressed concern that Katrina might push its storm surge over the city\'s levees and flood walls. In one conference, he stated, "I do not think anyone can tell you with confidence right now whether the levees will be topped or not, but that\'s obviously a very, very great concern.""Transcripts, tape show Bush, Brown warned on Katrina", CNN.com, March 2, 2006. Retrieved on 2007-04-22.
On August 28, as the sheer size of Katrina became clear, the NHC extended the tropical storm warning zone to cover most of the Louisiana coastline and a larger portion of the Florida Panhandle. The National Weather Service\'s New Orleans/Baton Rouge office issued a vividly-worded bulletin predicting that the area would be "uninhabitable for weeks" after "devastating damage" caused by Katrina, which at that time rivaled the intensity of Hurricane Camille."NWS bulletin." National Weather Service/New Orleans, Louisiana. August 28, 2005. Retrieved on 2007-07-30.
Voluntary and mandatory evacuations were issued for large areas of southeast Louisiana as well as coastal Mississippi and Alabama. About 1.2 million residents of the Gulf Coast were covered under a voluntary or mandatory evacuation order.
In a September 26, 2005 hearing, Michael Brown was questioned by Republican members of Congress about FEMA\'s response. During that hearing, Representative Stephen Buyer (R-IN) inquired as to why Bush\'s declaration did not include Orleans, Jefferson, or Plaquemines parishes."Former FEMA Director Testifies Before Congress", nytimes.com, 2005-09-27. Retrieved on 2007-09-01. (In fact, the declaration did not include any of Louisiana\'s coastal parishes, whereas the coastal counties were included in the declarations for MississippiBush, George W.

Brown testified that this was because Governor Blanco had not included those parishes in her initial request for aid, a decision that he found "shocking." After the hearing, though, Blanco released a copy of her letter, which requested assistance for "all the southeastern parishes including the New Orleans Metropolitan area and the mid state Interstate I-49 corridor and northern parishes along the I-20 corridor that are accepting [evacuated citizens].""[1]."

On August 26, the state of Mississippi activated its National Guard in preparation for the storm\'s landfall. Additionally, the state government activated its Emergency Operations Center the next day, and local governments began issuing evacuation orders. By 7:00 p.m. EDT on August 28, 11 counties and eleven cities issued evacuation orders, a number which increased to 41 counties and 61 cities by the following morning. Moreover, 57 emergency shelters were established on coastal communities, with 31 additional shelters available to open if needed.United States Congress (February 19, 2006). A Failure of Initiative: Final Report of the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina (PDF), Washington, DC: Government Printing Office. Retrieved on 2006-04-10. Louisiana\'s hurricane evacuation plan calls for local governments in areas along and near the coast to evacuate in three phases, starting with the immediate coast 50 hours before the start of tropical storm force winds. Persons in areas designated Phase II begin evacuating 40 hours before the onset of tropical storm winds and those in Phase III areas (including New Orleans) evacuate 30 hours before the start of such winds.Louisiana Homeland Security and Emergency Preparedness. Louisiana Citizen Awareness and Disaster Evacuation Guide. Retrieved on 2006-07-20.
Many private care-taking facilities that relied on bus companies and ambulance services for evacuation were unable to evacuate their charges. Fuel and rental cars were in short supply and many forms of public transportation had been shut down well before the storm arrived.Rulon, Malia; Scott, Katerine Hutt. "Evacuation plan failed to consider those without transportation." Burlington Free Press. March 11, 2006. Retrieved on 2006-06-05. Some estimates claimed that 80% of the 1.3 million residents of the greater New Orleans metropolitan area evacuated, leaving behind substantially fewer people than remained in the city during the Hurricane Ivan evacuation.Brown, Aaron.

By August 26, the possibility of unprecedented cataclysm was already being considered. Many of the computer models had shifted the potential path of Katrina 150 miles (240 km) westward from the Florida Panhandle, putting the city of New Orleans right in the center of their track probabilities; the chances of a direct hit were forecast at 17%, with strike probability rising to 29% by August 28."Hurricane Katrina Probabilities Report Number 15," & "Hurricane Katrina Probabilities Report Number 21." National Hurricane Center. August 26, 2005. Retrieved on 2006-06-05. This scenario was considered a potential catastrophe because some parts of New Orleans and the metro area are below sea level. Since the storm surge produced by the hurricane\'s right-front quadrant (containing the strongest winds) was forecast to be 28 feet (8.5 m), emergency management officials in New Orleans feared that the storm surge could go over the tops of levees protecting the city, causing major flooding.Drye, Willie. "Hurricane Katrina Pulls Its Punches in New Orleans." National Geographic. August 29, 2005. Retrieved on 2006-06-05.
At a news conference at 10:00 a.m. on August 28, shortly after Katrina was upgraded to a Category 5 storm, New Orleans mayor Ray Nagin ordered the first ever mandatory evacuation of the city, calling Katrina "a storm that most of us have long feared."Staff Writer. "Katrina Heads for New Orleans." Fox News/Associated Press. August 29, 2005. Retrieved on 2006-06-05. The city government also established several "refuges of last resort" for citizens who could not leave the city, including the massive Louisiana Superdome, which sheltered approximately 26,000 people and provided them with food and water for several days as the storm came ashore.Staff Writer."26,000 shelter at Superdome." Times-Picayune. August 28, 2005. Retrieved on 2006-06-05.
Many people living in the area were unaware when Katrina strengthened from a tropical storm to a hurricane in one day and struck southern Florida near the Miami-Dade – Broward county line. The hurricane struck between the cities of Aventura, in Miami-Dade County, and Hallandale, in Broward County, on August 25, 2005. However, National Hurricane Center (NHC) forecasts had correctly predicted that Katrina would intensify to hurricane strength before landfall, and hurricane watches and warnings were issued 31.5 hours and 19.5 hours before landfall, respectively — only slightly less than the target thresholds of 36 and 24 hours.
Florida Governor Jeb Bush declared a state of emergency on August 24 in advance of Hurricane Katrina\'s landfall in Florida. Shelters were opened and schools closed in several counties in the southern part of the state. A number of evacuation orders were also issued, mostly voluntary, although a mandatory evacuation was ordered for at-risk housing in Martin County.Staff writer.

On August 29, Katrina\'s storm surge caused 53 different levee breaches in greater New Orleans submerging eighty percent of the city. A June 2007 expert report stated that two-thirds of the flooding were due to levee breaches [2]. The storm surge also devastated the coasts of Mississippi and Alabama, making Katrina the most destructive and costliest natural disaster in the history of the United States, and the deadliest hurricane since the 1928 Okeechobee Hurricane. The total damage from Katrina is estimated at $81.2 billion (2005 U.S. dollars), nearly double the cost of the previously most expensive storm, Hurricane Andrew, when adjusted for inflation.United States Department of Commerce (June 2006).

Federal disaster declarations covered 90,000 square miles (233,000 km²) of the United States, an area almost as large as the United Kingdom. The hurricane left an estimated three million people without electricity. On September 3, 2005, Homeland Security Secretary Michael Chertoff described the aftermath of Hurricane Katrina as "probably the worst catastrophe, or set of catastrophes," in the country\'s history, referring to the hurricane itself plus the flooding of New Orleans."The Aftermath of Katrina: Transcript of CNN Live Saturday."

Hurricane Katrina first made landfall on August 25, 2005 in South Florida where it hit as a Category 1 hurricane, with 80 mph (130 km/h) winds. Rainfall was heavy in places and exceeded 14 inches (350 mm) in Homestead, Florida, and a storm surge of 3 – 5 feet (1.5 m) was measured in parts of Monroe County. More than 1 million customers were left without electricity, and damage in Florida was estimated at between 1 and 2 billion dollars, with most of the damage coming from flooding and overturned trees. There were 14 fatalities reported in Florida as a result of Hurricane Katrina.
Most of the Florida Keys experienced tropical-storm force winds from Katrina as the storm\'s center passed to the north, with hurricane force winds reported in the Dry Tortugas. Rainfall was also high in the islands, with 10 inches (250 mm) falling on Key West. On August 26, a strong F1 tornado formed from an outer rain band of Katrina and struck Marathon. The tornado damaged a hangar at the airport there and caused an estimated 5 million dollars in damage.Devenas, Andy "Marathon Tornado Survey Report." NWS Key West. Retrieved on 2006-06-05.
Although Hurricane Katrina stayed well to the north of Cuba, on August 29 it brought tropical-storm force winds and rainfall of over 8 inches (200 mm) to western regions of the island. Telephone and power lines were damaged and around 8,000 people were evacuated in the Pinar del Río Province. According to Cuban television reports the coastal city of Surgidero de Batabano was 90% underwater.Staff Writer. "Hurricane Katrina batters western Cuba."
Flooding in Venice, Louisiana
On August 29 Hurricane Katrina made landfall near Buras, Louisiana with 125 mph (205 km/h) winds, as a strong Category 3 storm. However, as it had only just weakened from Category 4 strength and the radius of maximum winds was large, it is possible that sustained winds of Category 4 strength briefly impacted extreme southeastern Louisiana. Although the storm surge to the east of the path of the eye in Mississippi was higher, a very significant surge affected the Louisiana coast. The height of the surge is uncertain because of a lack of data, although a tide gauge in Plaquemines Parish indicated a storm tide in excess of 14 feet (4.3 m) and a 12 foot (3 m) storm surge was recorded in Grand Isle.
Hurricane Katrina also brought heavy rain to Louisiana, with 8 – 10 inches (200 – 250 mm) falling on a wide swath of the eastern part of the state. In the area around Slidell, the rainfall was even higher, and the highest rainfall recorded in the state was approximately 15 inches (380 mm). As a result of the rainfall and storm surge the level of Lake Pontchartrain rose and caused significant flooding along its northeastern shore, affecting communities from Slidell to Mandeville. Several bridges were destroyed, including the I-10 Twin Span Bridge connecting Slidell to New Orleans. Almost 900,000 people in Louisiana lost power as a result of Hurricane Katrina.Staff Writer.

Hard-hit St. Bernard Parish was flooded due to breaching of the levees that contained a navigation channel called the Mississippi River Gulf Outlet (MR-GO). The search for the missing was slow. According to an interview in the New Orleans Times-Picayune, the coroner was still trying to get a list of missing from the Red Cross in November 2005. While there were some victims on this list whose bodies were found in their homes, the vast majority were tracked down through word-of-mouth and credit card records. As of December 2005, the official missing list in the Parish stood at 47.Cannizaro, Steve. "List of Missing Residents Down to 47, and More..." St. Bernard Parish Government (press release).

As the eye of Hurricane Katrina swept to the northeast, it subjected the city to hurricane conditions for hours. Although power failures prevented accurate measurement of wind speeds in New Orleans, there were a few measurements of hurricane-force winds. From this the NHC concluded that it is likely that much of the city experienced sustained winds of Category 1 or Category 2 strength.
Katrina\'s storm surge led to 53 levee breaches in the federally built levee system protecting metro New Orleans. Failures occurred in New Orleans, Louisiana and surrounding communities especially St. Bernard Parish. The Mississippi River Gulf Outlet (MR-GO) breached its levees in approximately 20 places, flooding much of east New Orleans, most of Saint Bernard Parish and the East Bank of Plaquemines Parish. The major levee breaches in the city included breaches at the 17th Street Canal levee, the London Avenue Canal, and the wide, navigable Industrial Canal, which left approximately 80% of the city flooded.Murphy, Verity. "Fixing New Orleans\' thin grey line." BBC News. October 4, 2005. Retrieved on 2006-06-05.
Most of the major roads traveling into and out of the city were damaged. The only routes out of the city were the westbound Crescent City Connection and the Huey P. Long Bridge, as large portions of the I-10 Twin Span Bridge traveling eastbound towards Slidell, Louisiana had collapsed. Both the Lake Pontchartrain Causeway and the Crescent City Connection only carried emergency traffic.Gordon, Meghan. "Causeway closed but hardly damaged." Times Picayune. August 31, 2005.

The Gulf coast of Mississippi suffered massive damage from the impact of Hurricane Katrina on August 29, leaving 238 people dead, 67 missing, and billions of dollars in damage: bridges, barges, boats, piers, houses and cars were washed inland.Haley Babour (January 6, 2006). Information Relating to the Federal Appropriations for Katrina Recovery. Office of the Governor, Mississippi. Retrieved on 2006-09-27. Katrina traveled up the entire state, and afterwards, all 82 counties in Mississippi were declared disaster areas for federal assistance, 47 for full assistance.
After making a brief initial landfall in Louisiana, Katrina had made its final landfall near the state line, and the eyewall passed over the cities of Bay St. Louis and Waveland as a Category 3 hurricane with sustained winds of 120 mph (195 km/h). Katrina\'s powerful right-front quadrant passed over the west and central Mississippi coast causing a powerful 27 foot (8.2 m) storm surge, which penetrated 6 miles (10 km) inland in many areas and up to 12 miles (20 km) inland along bays and rivers; in some areas, the surge crossed Interstate 10 for several miles. Hurricane Katrina brought strong winds to Mississippi which caused significant tree damage throughout the state. The highest unofficial reported wind gust recorded from Katrina was one of 135 mph (217 km/h) in Poplarville, in Pearl River County.
Damage to Long Beach, Mississippi following Hurricane Katrina
The storm also brought heavy rains with 8 – 10 inches (200 – 250 mm) falling in southwestern Mississippi and rain in excess of 4 inches (100 mm) falling throughout the majority of the state. Katrina caused eleven tornadoes in Mississippi on August 29, some of which damaged trees and power lines.
Battered by wind, rain and storm surge, some beachfront neighborhoods were completely leveled. Preliminary estimates by Mississippi officials calculated that 90% of the structures within half a mile of the coastline were completely destroyed,Staff Writer. "Mississippi Coast Areas Wiped Out."

One apartment complex with approximately thirty residents seeking shelter inside collapsed. More than half of the 13 casinos in the state, which were floated on barges to comply with Mississippi land-based gambling laws, were washed hundreds of yards inland by waves.
A number of streets and bridges were washed away. On U.S. Highway 90 along the Mississippi Gulf Coast, two major bridges were completely destroyed: the Bay St. Louis - Pass Christian bridge, and the Biloxi - Ocean Springs bridge. In addition, the eastbound span of the I-10 bridge over the Pascagoula River estuary was damaged. In the weeks after the storm, with the connectivity of the coastal U.S. Highway 90 shattered, traffic traveling parallel to the coast was reduced to two lanes on the remaining I-10 span.

All three coastal counties of the state were severely affected by the storm. Katrina\'s surge was the most extensive, as well as the highest, in the documented history of the United States; large portions of both Hancock, Harrison, and Jackson Counties were inundated by the storm surge, in all three cases affecting most of the populated areas.Federal Emergency Management Agency (November 2005). Mississippi Hurricane Katrina Surge Inundation and Advisory Base Flood Elevation Map Panel Overview (PDF). FEMA. Retrieved on 2006-07-16. Surge covered almost the entire lower half of Hancock County, destroying the coastal communities of Clermont Harbor and Waveland, much of Bay St. Louis, and flowed up the Jourdan River, flooding Kiln. In Harrison County, Pass Christian was completely inundated, along with a narrow strip of land to the east along the coast, which includes the cities of Long Beach and Gulfport; the flooding was more extensive in communities such as D\'Iberville, which borders Back Bay. Biloxi, on a peninsula between the Back Bay and the coast, was particularly hard hit, especially the low-lying Point Cadet area. In Jackson County, storm surge flowed up the wide river estuary, with the combined surge and freshwater flooding cutting the county in half. Remarkably, over 90% of Pascagoula, the easternmost coastal city in Mississippi, and about 75 miles (121 km) east of Katrina\'s landfall near the Louisiana-Mississippi border, was flooded from surge at the height of the storm. Other large Jackson County neighborhoods such as Porteaux Bay and Gulf Hills were severely damaged with large portions being completely destroyed, and St. Martin was hard hit; Ocean Springs, Moss Point, Gautier, and Escatawpa also suffered major surge damage.
Mississippi Emergency Management Agency officials also recorded deaths in Forrest, Hinds, Warren, and Leake counties. Over 900,000 people throughout the state experienced power outages.
Mobile, Alabama: Downtown flood waters came up Mobile\'s Federal Courthouse steps 29-Aug-2005.
Although Hurricane Katrina made landfall well to the west, Alabama and the Florida Panhandle were both affected by tropical-storm force winds and a storm surge varying from 12 to 16 ft (3-5 m) around Mobile Bay, with higher waves on top. Sustained winds of 67 mph (107 km/h) were recorded in Mobile, Alabama, and the storm surge there was approximately 12 feet (3.7 m). The surge caused significant flooding several miles inland along Mobile Bay. Four tornadoes were also reported in Alabama. Ships, oil rigs, boats and fishing piers were washed ashore along Mobile Bay: the cargo ship M/V Caribbean Clipper and many fishing boats were grounded at Bayou La Batre.
An oil rig under construction along the Mobile River broke its moorings and floated 1.5 miles (2 km) northwards before striking the Cochrane Bridge just outside Mobile. No significant damage resulted to the bridge and it was soon reopened. The damage on Dauphin Island was severe, with the surge destroying many houses and cutting a new canal through the western portion of the island. An offshore oil rig also became grounded on the island. As in Mississippi, the storm surge caused significant beach erosion along the Alabama coastline. More than 600,000 people lost power in Alabama as a result of Hurricane Katrina and two people died in a traffic accident in the state.
Along the Florida Panhandle the storm surge was typically about five feet (1.5 m) and along the west-central Florida coast there was a minor surge of 1 – 2 feet (0.3 – 0.6 m). In Pensacola, Florida 56 mph (90 km/h) winds were recorded on August 29. The winds caused damage to some trees and structures and there was some minor flooding in the Panhandle. There were two indirect fatalities from Katrina in Walton County as a result of a traffic accident. In the Florida Panhandle, 77,000 customers lost power.Associated Press, "Katrina at a Glance" (August 31, 2005), page 4A, Mobile Register, web: MobileRegister-083105-PDF.

Northern and central Georgia were affected by heavy rains and strong winds from Hurricane Katrina as the storm moved inland, with more than 3 inches (75 mm) of rain falling in several areas. At least 18 tornadoes formed in Georgia on August 29, the most on record in that state for one day in August. The most serious of these tornadoes was a F2 tornado which affected Heard County and Carroll County. This tornado caused 3 injuries and one fatality and damaged several houses. In addition this tornado destroyed several poultry barns, killing over 140,000 chicks. The other tornadoes caused significant damages to buildings and agricultural facilities. In addition to the fatality caused by the F2 tornado, there was another fatality in a traffic accident.Westbrook, Robby; WFO Peachtree City Staff.

Hurricane Katrina weakened as it moved inland, but tropical-storm force gusts were recorded as far north as Fort Campbell, Kentucky on August 30, and the winds damaged trees in New York. The remnants of the storm brought high levels of rainfall to a wide swath of the eastern United States, and rain in excess of 2 inches (50 mm) fell in parts of 20 states.Staff Writer.

The remnants of Katrina were absorbed by a new cyclone to its east across Pennsylvania. This second cyclone continued north and affected Canada on August 31. In Ontario there were a few isolated reports of rain in excess of 100 mm (4 inches) and there were a few reports of damage from fallen trees.Perreault, Bob. "Brockville May Have Set Rain Record."

The Impact of Hurricane Katrina on Biological Resources (PDF). Congressional Research Service. Retrieved on 2006-06-05. The total loss to the forestry industry from Katrina is calculated to rise to about $5 billion. Furthermore, hundreds of thousands of local residents were left unemployed, which will have a trickle-down effect as fewer taxes are paid to local governments. Before the hurricane, the region supported approximately one million non-farm jobs, with 600,000 of them in New Orleans. It is estimated that the total economic impact in Louisiana and Mississippi may exceed $150 billion.Burton, Mark L.; Hicks, Michael J.
