We spent a lot of time in New Orleans looking at the damage left by the hurricane and the flooding and seeing the areas that are still underwater and in a very bad way.
We went with a rescue team who were going through areas and breaking into houses to make sure no-one was still there.
They've also been rescuing lots of pets and taking them to shelters where they can be looked after and get the food and water they've been missing.

We went to a centre run by Fema - Federal Emergency Management Agency - and the Red Cross which helps people get themselves sorted out as many of them have no homes to go back to.
We filmed with a local sheriff and talked with him about the night of the storm. He's lost his house completely and his family have been moved to north Louisiana.
We also met a boy called William whose house was ripped apart by the storm and was then flooded as well.
We went to look at his house, and it was almost completely destroyed. It will probably have to be bulldozed.
There were bits of other people's houses in their front yard, and their possessions were all over the place.

We had to get up at 5am to travel to Baton Rouge, the capital of Louisiana.
A lot of the relief effort is there, as are a lot of evacuated families as it's far away from the region affected by the hurricane.
We met some people from the US Red Cross there, and ended up driving into outskirts of New Orleans. We spent the night in the city with the Red Cross

We went to the Houston Astrodome, which is a huge old sports stadium.
Lots of the evacuees have been sent there from areas affected by the hurricane. The number of people there were incredible.
There's a big centre there for children who were separated from their parents in the escape from New Orleans when they were crammed into buses and sent away from the city.
Around 1,700 kids were separated from their parents, and they're trying to 1700) kids, they trying to find out if their parents are alive, and then where they are so they can meet up.
The internet and mobile phones - called cellphones in the US - have been really useful as websites have been set up to help people contact each other.
The cellphones were very useful as they were small enough for people to take with them when they were evacuated - unlike their other possessions.
There are still lots of kids without their families.
We filmed with some kids who have found their parents and were being flown off to be reunited with them.
