I would not worry about the GFDL this far out on TD3. I think Bonnie is going to be the more immediate concern. GFDL has a bad habit of blowing up a still unformed storm to cat 3. Cuba always seems to take a little more out of a system then what the GFDL takes into account, IMHO. I'm not sold on those dynamics for it curving so rapidly. If anything, I think the system that is suppose to cause this turn will not arrive as early as predicted. The models have seen to be a little agressive on moving troughs in and seem to back off that after a few days.
