Not to shoot your projections down, but I see big desscrepancies in your forecast positions and the NHC positions. With this said, why should someone believe your forecast? Why are your projected positions so different from the NHC positions?

I have seen you posts on here NUMEROUS times before with your projections and forecast for other storms, and they always appear to be so far off from what the NHC projects, it makes me wonder what your real objective is.

Here are the NHC projections for Frances. Compare them to yours and explain why and how, yours can be so different!

With his track trend she will most likely go out to sea according to him.

Actually, I don't see that much of a difference there throughout the period, and especially in the net result at 120 hours--where those coordinates are very close to each other relative to time.

I will say though, that the biggest difference is caused by our uses of model guidance...NHC seems to use it a bit more intensely than I do. Not that I ignore it, but I don't mind throwing out a model with a legit reason--and that's not including not matching my track--I'll throw how a track for systematic or synoptic reasons in most cases.

In this particular situation, I have had the ridge re-establishing itself slower than the models have anticipated--I may end up sliding left, but if I do, I don't think it will be much. Right now I'm not concerned with it terribly--I've been dead on track for four forecasts now--and really if you think about it, the farther south this thing goes...the better for CONUS (more room to make a turn).

I like your forecast. You don't hide anything (namely the intensity) like the NHC usually does.

Just because someone gets a different forecast doesnt mean that they are wrong and NHC is right. NHC has and will be wrong in the future. It means that the analysis of the same data can yield two different interpretations, suggesting some uncertainty on future happenings (FYI: I am right of NHC in the latest forecast)
