• What actions did the U.S. Coast Guard take in preparation for and response to Hurricane Katrina?: The U.S. Coast Guard pre-positioned resources, activated reservists, and staged aircraft before the storm. Post-landfall, they conducted extensive search and rescue operations, saving over 33,500 people stranded in New Orleans and along the coastlines. Their efforts were recognized with a Presidential Unit Citation for their critical role.
• How many people did the U.S. Coast Guard rescue during Hurricane Katrina?: The U.S. Coast Guard executed extensive search and rescue operations, saving in excess of 33,500 individuals stranded in New Orleans and adjacent coastal areas during Hurricane Katrina. Their critical contributions were acknowledged with a Presidential Unit Citation.
• Which government entities faced criticism for their response to Hurricane Katrina, and which were commended?: The emergency response efforts by federal, state, and local governments were subjected to widespread criticism due to perceived mismanagement and delayed interventions, leading to significant repercussions for officials, including the resignation of FEMA Director Michael D. Brown. In contrast, entities such as the United States Coast Guard, National Hurricane Center, and National Weather Service received commendations for their effective operational performance, with the NHC particularly recognized for its accurate forecasting.

• Why was the name "Katrina" retired, and when did this decision occur?: The designation "Katrina" was officially retired by the World Meteorological Organization in April 2006, a decision prompted by the storm's substantial fatality count and extensive property devastation along the U.S. Gulf Coast. This nomenclature retirement precludes its future use for Atlantic tropical cyclones, with "Katia" designated as its successor for the 2011 season.
• What were the primary impacts of Hurricane Katrina, and how does it rank in terms of cost and intensity for Atlantic basin hurricanes?: Hurricane Katrina was a catastrophic tropical cyclone responsible for 1,392 fatalities and an estimated $125 billion in damages, with profound impacts on New Orleans and adjacent regions. It ranks as the costliest tropical cyclone in the Atlantic basin (tied with Hurricane Harvey) and was the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States by barometric pressure. Its intensity peaked at Category 5 in the Gulf of Mexico.
• How did Hurricane Katrina rank in terms of intensity for Atlantic hurricanes making landfall in the contiguous United States?: Katrina was the fourth-most intense Atlantic hurricane on record to make landfall in the contiguous United States, measured by barometric pressure. It was surpassed only by the 1935 Labor Day hurricane, Hurricane Camille (1969), and Hurricane Michael (2018).

• What was the estimated extent of flooding in New Orleans caused by Hurricane Katrina's storm surge?: The storm surge from Hurricane Katrina caused 53 breaches in the levee system protecting the greater New Orleans area, submerging approximately 80% of the city. A significant portion of this flooding, about two-thirds, was attributed to failures of the city's floodwalls.

Related Concepts:

• What were the findings of studies concerning the mental health of Hurricane Katrina evacuees?: Studies investigating the psychological well-being of Hurricane Katrina evacuees revealed substantial psychosocial needs. For instance, a study conducted among evacuees in Dallas indicated that over one-quarter met the diagnostic criteria for major depressive disorder, and approximately one-third were referred for mental health services addressing depression and post-traumatic stress disorder (PTSD).

• How did Hurricane Katrina affect birth outcomes, according to a study conducted years after the disaster?: A study investigating birth outcomes following Hurricane Katrina found associations between experiencing significant damage during the event and adverse outcomes, suggesting long-term impacts on pregnancy.

Related Concepts:

• How did the U.S. media's coverage of Hurricane Katrina evolve, particularly regarding online platforms?: The media's coverage of Hurricane Katrina underwent a significant evolution, with online platforms such as NOLA.com assuming a critical role. In the context of widespread communication infrastructure failures, journalists functioned as essential conduits of information, and the website emerged as a vital nexus for coordinating rescue operations and facilitating family reunification, marking a pivotal moment in journalistic practice that influenced Pulitzer Prize categories.
