On Monday, August 29, 2005 Hurricane Katrina hit the American coast near New Orleans. The storm had formed over the Caribbean Sea almost a week earlier. It became the fourth largest storm that has ever been recorded in the Atlantic Ocean. Winds reached speeds of over 340 km an hour. Although the centre of the hurricane did not pass directly over New Orleans most of the city was flooded by the storm. New Orleans is located in a really dangerous area. It lies above the Gulf of Mexico where many storms and hurricanes pass through. The Mississippi River also runs through the middle of the city. Katrina brought along heavy rainfall and about 80% of the city was flooded. Most of the city's population was evacuated, but about one hundred thousand had to stay behind, mostly poor people and blacks who had no cars and couldn’t get out. They were trapped in the floods for days without food and water. As a result thousands of people died in one of the biggest catastrophes in American history.
