More than 7 million evacuated as Irma hits Southeast U.S.

400-mile-wide Hurricane Irma "zeroed in on the Tampa Bay region early Monday after hammering much of Florida with roof-ripping winds, gushing floodwaters and widespread power outages," per AP:

• "In one of the largest U.S. evacuations, nearly 7 million people in the Southeast were warned to seek shelter elsewhere, including 6.4 million in Florida alone."
• "More than 3.3 million homes and businesses across the state lost power."
• "Upon leaving Florida, a weakened Irma is expected to push into Georgia, Alabama, Mississippi, Tennessee and beyond."
• "A tropical storm warning was issued for the first time ever in Atlanta, where many schools canceled classes because of the storm."
