Florida has asked 5.6 million people to evacuate ahead of Hurricane Irma, or more than one quarter of the state’s population, according to state emergency officials.

Andrew Sussman, the state’s hurricane program manager, said Friday the total includes people throughout the southern half of the state as well as those living in inland Florida in substandard housing who were also told leave due to the dangerous storm that will slam the state this weekend.

Florida is the nation’s third-largest state with nearly 21 million people according to the U.S. Census.

For days Gov. Rick Scott has been urging residents to evacuate, especially those who live in coastal areas that could be flooded due to the walls of water expected from Irma’s arrival.
