The Impact of Hurricane Katrina by: a 9th grade student

Hurricane Katrina may be the most memorable storm in New Orleans history, but its trajectory across the Pelican State was far from unique. Louisiana was hit by 49 of the 273 hurricanes that made landfall on the American Atlantic Coast between 1851 and 2004. In addition, eighteen of the ninety-two major hurricanes with Saffir-Simpson ratings of category 3 or above have struck the state (U.S. mainland hurricane strikes by state, 1851-2004). On average, one major storm crosses within 100 nautical miles of New Orleans every decade
How do hurricanes form? Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. The generic, scientific term for these storms, wherever they occur, is tropical cyclone.

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.

An estimated 80% of New Orleans was under water, up to 20 ft deep in places. Hurricane Katrina caused $81 billion in property damages, but it is estimated that the total economic impact in Louisiana and Mississippi may exceed $150 billion, earning the title of costliest hurricane ever in US history.
Hurricane Katrina Flooding

The economic effects of Hurricane Katrina, which hit Louisiana, Florida, and Mississippi in late August 2005, were far-reaching. 2006, the Bush Administration on sought $105 billion for repairs and reconstruction in the region, making it the costliest natural disaster in US history.

How much money was spent on Hurricane Katrina? In New Orleans alone, 134,000 housing units — 70% of all occupied units — suffered damage from Hurricane Katrina and the subsequent flooding. Recovery funding. Of the $120.5 billion in federal spending, the majority — approximately $75 billion — went to emergency relief, not rebuilding.
What is the environmental impact of a hurricane? Hurricanes generate strong winds that can completely defoliate forest canopies and cause dramatic structural changes in wooded ecosystems. Animals can either be killed by hurricanes or impacted indirectly through changes in habitat and food availability caused by high winds, storm surge, and intense rainfall.
