Irma's evolving forecast

Hurricane Irma followed a tightly forecasted path all week as it raked the the Caribbean and set its sights on Florida. Friday's forecast had Miami set up for a direct hit, but the center line shifted west and put The Keys, Naples and Tampa directly in the storm's path. Millions of people throughout the state were without electricity Monday as Irma's remnants made their way into Georgia and the Carolinas.

Here's a look at how the forecast changed, and the track shifted, throughout the week.
