# Hurricane Katrina

## What is a Hurricane?

A hurricane is a large mass of moving air that moves in a counterclockwise direction. A hurricane is also a very destructive storm; it can have winds up to 157 mph or higher. Now you may be asking yourself, can hurricanes be that destructive? Yes, yes they can. I've seen a picture of a hurricane dropping a house on a truck. I've heard of hurricanes pulling houses right off the foundation. That's just some of what hurricanes can do.

Now if you look to your left you will see a picture of an house on top of an upside down truck. This picture is just one of many pictures that show the destruction that hurricane Katrina caused.

## Formation of a Hurricane

Though hurricanes are very destructive storms they have to form first. So I guess I will tell you how they form. First a hurricane needs warm ocean water (above 80 f). Next there needs to be wind moving together to push other air up; then when it pushes humid air up, it makes storm clouds. there is also light wind outside the hurricane to it grow and grow. So that's the steps of the formation of a hurricane.

If you look to the right you can see a picture of step on how a hurricane forms. This picture to the right shows you how a hurricane forms.

## Categorizing a Hurricane

The way people categorize hurricanes is they use a scale called "The Saffir Simpson Hurricane Wind Scale". The way this scale works is you find the wind speed of the hurricane. Then when you have the wind speed you need to look at the scale and find out the category of the hurricane. Say you have a big hurricane and it's wind speed is 160 mph. Here is the scale

Category 1 74-95 mph

Category 2 96-110 mph

Category 3 111-129 mph

Category 4 130-156 mph

Category 5 157 or higher mph.

So 160 mph would be category 5 because it's higher then 157 mph which is the lowest wind speed a category 5 hurricane can have.

If you look to the left you will see a satellite picture of Hurricane Katrina. This picture is of when Katrina was moving though the Gulf of Mexico.

## All About Naming a Hurricane

In 1953, they started naming hurricanes but they only gave hurricanes female names because they said that hurricanes have a lot of the same characteristics as women do. Then they thought that it wasn't right that only women got to have a hurricane named after them. So in 1979, they added male names to the lists.

Now I think it's time to tell you about how hurricanes are named. Well they have six lists of names. Each year they use one of the lists. Every six years they start back with the first list. Also if a storm is really bad like say Katrina, was then they take that name off the list and add a new one. The lists go in alphabetic order so the first hurricane of the years name will start with an A and so on.

If you look to the right you will see a picture of what looks like a lake but look again though's are roofs and and that is not a lake that is flooding from Hurricane Katrina. This picture is one of many of the flooding that Katrina caused. If you look hard at this you can tell the flooding is up to the roof now this is very deep and this was a very destructive storm.

## Hurricane Katrina

The famous hurricane we are going to talk about today is Hurricane Katrina. Katrina happened in 2005; it was a very destructive hurricane. Katrina hit land about three times first time in South Florida, second time was in Buras, Louisiana, third time was on the Louisiana and Mississippi border. Katrina turned into a category 5 right before it hit land the second time and then turned into a category 3 the third time it hit land and if you look to the left you will see a picture of the path Hurricane Katrina took. Katrina also caused \$75 billion in damage and 1,200 deaths recorded and the highest wind speed was 175 mph. Katrina was a very destructive storm.

So I hope that this was a very helpful and informative article. I also hope that this article has helped you realize how destructive and dangerous hurricanes can be. Also if a hurricane is coming be safe, and get out of the hurricanes way.
