Hurricane Irma was downgraded to a Category 3 storm Saturday, as its eye inched closer to South Florida. It's still expected to hit the state as a Category 4 on Sunday.

The storm has killed at least 20 people since roaring out of the open Atlantic and chewing through a string of Caribbean islands. Governors of four Southeast states have declared states of emergency ahead Irma's arrival on the U.S mainland.

Where will Irma hit Florida?

The worst of Hurricane Irma is now forecast along the west coast of Florida after its track shifted overnight. Irma will act like a giant buzzsaw as it plows up the state's west coast into Monday, battering cities such as Key West, Naples, Fort Myers, Sarasota, and the Tampa-St. Pete area with hurricane-force winds, torrential rain, and devastating storm-surge inundation. “This will be the worst single hurricane to hit Florida since Hurricane Andrew in 1992,” said meteorologist Joel N. Myers, head of AccuWeather.
