I think any time I have seen a hurricane look like Irma does now on satellite its days are numbered. It has no clear eye and its "flow" has been significantly disrupted. Hurricanes sometimes recover incredibly once over warm water again, but Irmas time may be limited to do that.
The problem continues to be projecting how fast it might regenerate and what exact path it takes with regard to Florida / the Cuban coast. The slow down in path coupled with the weakening gives a great ray of hope, but also complicates things. If people become complacent / decide to return, and then Irma takes enough time over open water and quickly becomes a category 5 again, the disaster could be even worse. But if she dies a miserable death without any discussion along these lines from mets / officials, the population once again loses trust in the science even if it doesnt deserve that fate.
Again, if Irma had not interacted with Cuba we would easily be looking at one of the greatest disasters in U.S. history. Now it is my opinion that it will be difficult to achieve that, though still not impossible depending on the land / water interaction mentioned above. Floridians should be in wait and hope mode that the CAT 4 / 5 cane that was bearing down on them does not materialize and is instead a CAT 2/3. It is still too soon to tell which is going to happen.
The almighty Euro still forecasts a very clear eyed hurricane to slam into Florida in the next day or two.
