When is the last time you saw a discussion on the track that long? Anyways, the US threat is on. The discussion also mentions the storm is already above-average in size and that it will be even larger at 72 hours. The effects of Isidore could be felt for hundreds of miles--no kidding here. The time to prepare is now folks. Don't wait until late this week when the storm is getting ready to bear down.
Also, it looks like TD#13 has survived. It's in an area of some stronger shear, but it will be out of this in 24 hours. This could well be a significant cyclone eventually as well. For now we need to focus on Isidore, though.
