Reports: Irma’s severe flooding eyes Jacksonville, Florida, to Charleston, South Carolina

Irma has left over 6 million without power in Florida as the storm continues to bring life-threatening storm surge and powerful winds.

At least three people have died in the storm in the United States. Two law enforcement officers were in a fatal car accident on Sunday; the third person was in a single-vehicle accident in Orange County, Florida.

Irma made a second Florida landfall at Marco Island, Florida, on Sunday. The storm tore across the Florida Keys early Sunday morning. Irma weakened to a tropical storm on Monday morning over eastern Florida after a 12-day stretch at hurricane strength.

President Donald Trump has approved a major disaster declaration for Florida.

This is the first year that two Atlantic Basin hurricanes have made landfall at Category 4 strength in the U.S. in one season since records began in 1851.

Irma prompted the largest evacuation in U.S. history, taking 7 million out of their homes. More than 30 percent of Florida's entire population were asked to evacuate.
