Hurricane Irma killed at least 33 people in the US and flooded major cities including Jacksonville, Florida and Charleston, South Carolina.
Millions are without power in the Southeast. Almost every home in the Florida Keys is damaged, according to FEMA.
Before causing devastation in the United States, Irma hit Cuba late Friday as a Category 5 hurricane.
More than 40 people were killed when Irma tore through several Caribbean islands, knocking down trees and leveling buildings.
