I don't think Ida is an apt comparison to the storm of the century. That one was a completely different bird with the mass of extreme cold air and the jet stream behind it. It is the only time I can remember being in the 70's in the morning and seeing snow in the afternoon without getting on a plane. Not to mention it happened in Florida.

Assuming Ida continues on to hit the coast, unless the factors push it back into the Northern Caribbean for a few days after it emerges into the Gulf(a scenario with slight possibility but not one of the likely ones), I just can not see Ida becoming a dangerous storm to Florida. Ida is going to have to camp out near Cuba to really gain some strength. I am not saying it is not possible; but I would not be changing any plans to come to Florida because of Ida.
