Hurricane Isaac heading to America
America is preparing for a hurricane which is set to hit on Tuesday night.
President Barack Obama has declared a state of emergency in the state of Louisiana as Hurricane Isaac approaches.
Isaac was classed as a tropical storm but got more powerful and is now categorised as a hurricane.
It killed at least 24 people in Haiti and the Dominican Republic, and caused a lot of flooding and damage across the Caribbean.
Evacuations have already been ordered for some low-lying areas of Louisiana and Alabama.
Nearly seven years ago Hurricane Katrina devastated the city of New Orleans in Louisiana.
