We are starting to get a better picture of when and where Irma is expected to make landfall Sunday morning. As you can see on the attached National Weather Service map the storm will be felt in South Florida Sunday and continue up the state toward Orlando overnight into Monday. It will still be generating hurricane-force winds when it reaches Central Florida.
On Tuesday Irma is forecast as a Tropical Storm providing significant rainfall in Georgia, and by Wednesday it will be a Tropical Depression which will deliver rain and the possibility of tornadoes in the Northern Alabama/Tennessee area.
