Florida Gov. Rick Scott on Saturday asked another 700,000 residents to leave their homes before Hurricane Irma makes landfall, bringing the total number of people living in evacuation zones to more than 6.3 million. Scott said storm surges could reach up to 15 feet in some areas, with Irma expected to touch down in Florida on Sunday. NewsHour Weekend's Megan Thompson has more.
