The news of the day of course is that Florida is bracing for a Category 5 hurricane impact, and the governor has declared a state of emergency along with all that entails.
It is still quite far east, and it still has a long way to go, as evidenced from this GOES 16 satellite image this morning:
The backstory is that many, many, people, including myself, are hoping the trajectory forecasts are wrong, and that the uncertainty displayed in model output like this (from http://spaghettimodels.com/) , puts Irma outside of an impact in Florida, and out to sea.
