Hurricane Katrina

What do you remember about Hurricane Katrina? Most everyone, at least in the United States, remembers Katrina, one of the deadliest unforeseen weather events in history on August 29, 2005. No one expected it to become the nightmare storm that it became --- one of the deadliest in the United States. Over 1800 people lost their lives not only from the hurricane itself but also from the rising floodwaters that happened afterwards. There were literally millions of people who became homeless across the Gulf Coast including New Orleans.

According to the NOAA (National Oceanic and Atmospheric Administration), it caused $108 billion in damage, the costliest storm in U.S. history. And it all started from a simple tropical depression near the Bahamas. It became a hurricane category 1 and then was reduced back down to a tropical storm after moving across Florida. When it got into the Gulf of Mexico, it began to re-strengthen into a large upper-level anticyclone that totally covered the entire Gulf. By August 28, it had become a category 5 hurricane with winds of 175 mph. When it made landfall across the Louisiana-Mississippi border, it had slowed to a category 3 but still had sustained winds of 120 mph. Among the cities most affected by this monster hurricane were Gulfport and Biloxi in Mississippi and New Orleans in Louisiana.
