America has been hit by the largest number of tornadoes that the country has ever seen.
In just three days, between 25-28 April, 362 tornadoes struck the south of the country.
At least 350 people have died in the storms which have been the deadliest for 75 years.
Whole neighbourhoods have been destroyed, trees have been uprooted and emergency teams have been busy rescuing people from the rubble.
Hundreds of thousands of people are still without electricity.
President Barack Obama and his wife have travelled to the worst hit areas to see the amount of damage for themselves.
