Hurricane Rita is gaining strength in the Gulf of Mexico after lashing Florida and Cuba, and may hit the southern US soon.
New Orleans is being evacuated, because if Rita hits the city it could be badly flooded once more, after being damaged by Hurricane Katrina in August.
Satellite pictures suggest the Category Four storm will hit Texas later this week, bringing winds of 130mph.
Tens of thousands of people are leaving towns along the Gulf Coast.
Many of the people who had to leave New Orleans after Katrina are now being forced to leave Texas, where they had been taking shelter.
Rita passed in between Cuba and the US island chain known as the Florida Keys on Tuesday.

The hurricane season runs from the start of June to the end of November, and Rita is the 17th named storm this year.
