Hurricane Katrina was a large and destructive Category 5 Atlantic hurricane that caused over 1,800 fatalities and $125 billion in damage in late August 2005, especially in the city of New Orleans and the surrounding areas. It was at the time the costliest tropical cyclone on record and is now tied with 2017's Hurricane Harvey.
Early in the morning on August 29, 2005, Hurricane Katrina struck the Gulf Coast of the United States. When the storm made landfall, it had a Category 3 rating on the Saffir-Simpson Hurricane Scale‐it brought sustained winds of 100–140 miles per hour–and stretched some 400 miles across.
While the storm itself did a great deal of damage, its aftermath was catastrophic. Levee breaches led to massive flooding, and many people charged that the federal government was slow to meet the needs of the people affected by the storm. Hundreds of thousands of people in Louisiana, Mississippi and Alabama were displaced from their homes, and experts estimate that Katrina caused more than $100 billion in damage.
Hurricane Katrina: Before the Storm
The tropical depression that became Hurricane Katrina formed over the Bahamas on August 23, 2005, and meteorologists were soon able to warn people in the Gulf Coast states that a major storm was on its way. By August 28, evacuations were underway across the region. That day, the National Weather Service predicted that after the storm hit, “most of the [Gulf Coast] area will be uninhabitable for weeks… perhaps longer.”
New Orleans was at particular risk. Though about half the city actually lies above sea level, its average elevation is about six feet below sea level‐and it is completely surrounded by water. Over the course of the 20th century, the Army Corps of Engineers had built a system of levees and seawalls to keep the city from flooding. The levees along the Mississippi River were strong and sturdy, but the ones built to hold back Lake Pontchartrain, Lake Borgne and the waterlogged swamps and marshes to the city’s east and west were much less reliable.
Before the storm, officials worried that surge could overtop some levees and cause short-term flooding, but no one predicted levees might collapse below their designed height. Neighborhoods that sat below sea level, many of which housed the city’s poorest and most vulnerable people, were at great risk of flooding.
The day before Katrina hit, New Orleans Mayor Ray Nagin issued the city’s first-ever mandatory evacuation order. He also declared that the Superdome, a stadium located on relatively high ground near downtown, would serve as a “shelter of last resort” for people who could not leave the city. (For example, some 112,000 of New Orleans’ nearly 500,000 people did not have access to a car.) By nightfall, almost 80 percent of the city’s population had evacuated. Some 10,000 had sought shelter in the Superdome, while tens of thousands of others chose to wait out the storm at home.
By the time Hurricane Katrina struck New Orleans early in the morning on Monday, August 29, it had already been raining heavily for hours. When the storm surge (as high as 9 meters in some places) arrived, it overwhelmed many of the city’s unstable levees and drainage canals. Water seeped through the soil underneath some levees and swept others away altogether.
By 9 a.m., low-lying places like St. Bernard Parish and the Ninth Ward were under so much water that people had to scramble to attics and rooftops for safety. Eventually, nearly 80 percent of the city was under some quantity of water.
Hurricane Katrina: The Aftermath
Many people acted heroically in the aftermath of Hurricane Katrina. The Coast Guard rescued some 34,000 people in New Orleans alone, and many ordinary citizens commandeered boats, offered food and shelter, and did whatever else they could to help their neighbors.
Yet the government–particularly the federal government–seemed unprepared for the disaster. The Federal Emergency Management Agency (FEMA) took days to establish operations in New Orleans, and even then did not seem to have a sound plan of action.
Officials, even including President George W. Bush, seemed unaware of just how bad things were in New Orleans and elsewhere: how many people were stranded or missing; how many homes and businesses had been damaged; how much food, water and aid was needed. Katrina had left in her wake what one reporter called a “total disaster zone” where people were “getting absolutely desperate.”
Failures in Government Response
For one thing, many had nowhere to go. At the Superdome in New Orleans, where supplies had been limited to begin with, officials accepted 15,000 more refugees from the storm on Monday before locking the doors. City leaders had no real plan for anyone else. Tens of thousands of people desperate for food, water and shelter broke into the Ernest N. Morial Convention Center complex, but they found nothing there but chaos.
Meanwhile, it was nearly impossible to leave New Orleans: Poor people especially, without cars or anyplace else to go, were stuck. For instance, some people tried to walk over the Crescent City Connection bridge to the nearby suburb of Gretna, but police officers with shotguns forced them to turn back.
Katrina pummeled huge parts of Louisiana, Mississippi and Alabama, but the desperation was most concentrated in New Orleans. Before the storm, the city’s population was mostly black (about 67 percent); moreover, nearly 30 percent of its people lived in poverty. Katrina exacerbated these conditions and left many of New Orleans’s poorest citizens even more vulnerable than they had been before the storm.
In all, Hurricane Katrina killed nearly 2,000 people and affected some 90,000 square miles of the United States. Hundreds of thousands of evacuees scattered far and wide. According to The Data Center, an independent research organization in New Orleans, the storm ultimately displaced more than 1 million people in the Gulf Coast region.
Political Fallout From Hurricane Katrina
In the wake of the storm's devastating effects, local, state and federal governments were criticized for their slow, inadequate response, as well as for the levee failures around New Orleans. And officials from different branches of government were quick to direct the blame at each other.
“We wanted soldiers, helicopters, food and water,” Denise Bottcher, press secretary for then-Gov. Kathleen Babineaux Blanco of Louisiana told the New York Times. “They wanted to negotiate an organizational chart.”
New Orleans Mayor Ray Nagin argued that there was no clear designation of who was in charge, telling reporters, “The state and federal government are doing a two-step dance.”
President George W. Bush had originally praised his director of FEMA, Michael D. Brown, but as criticism mounted, Brown was forced to resign, as was the New Orleans Police Department Superintendent. Louisiana Governor Blanco declined to seek re-election in 2007 and Mayor Nagin left office in 2010. In 2014 Nagin was convicted of bribery, fraud and money laundering while in office.
The U.S. Congress launched an investigation into government response to the storm and issued a highly critical report in February 2006 entitled, “A Failure of Initiative.”
Changes Since Katrina
The failures in response during Katrina spurred a series of reforms initiated by Congress. Chief among them was a requirement that all levels of government train to execute coordinated plans of disaster response. In the decade following Katrina, FEMA paid out billions in grants to ensure better preparedness.
Meanwhile, the Army Corps of Engineers built a $14 billion network of levees and floodwalls around New Orleans. The agency said the work ensured the city's safety from flooding for the time. But an April 2019 report from the Army Corps stated that, in the face of rising sea levels and the loss of protective barrier islands, the system will need updating and improvements by as early as 2023.
August 23, 2005
August 31, 2005
- The storm initially formed as a tropical depression southeast of the Bahamas on August 23. By the evening of August 25, when it made landfall north of the Broward-Miami-Dade county line, it had intensified into a category 1 hurricane. With top winds of around 80 mph, the storm was relatively weak, but enough to knock out power for about 1 million and cause $630 million of damage.
- After passing over Florida, Katrina again weakened, and was reclassified as a tropical storm. But over the Gulf of Mexico, some 165 miles west of Key West, the storm gathered strength above the warmer waters of the gulf. On August 28, the storm was upgraded to a category 5 hurricane, with steady winds of 160 mph.
- By some estimates, between 80 and 90 percent of New Orleans’ population was able to evacuate the city prior to Katrina. Still, about 100,000 people were trapped in the city when the storm hit, and many took last-ditch refuge in the New Orleans Superdome and the Ernest J. Morial Convention Center as the storm approached. Some 25,000 crowded into the convention center, while more than 25,000 filled the Superdome.
- The Data Center, a New Orleans-based research organization, estimated that the storm and subsequent flooding displaced more than 1 million people, leaving hundreds of thousands of people homeless. It damaged more than a million housing units in the region. According to the National Oceanic and Atmospheric Administration (NOAA), Katrina is the costliest U.S. hurricane on record, inflicting some $125 billion in total damages.
