Thats interesting H2 the SST's in that region are definitly warm enough to sustain a storm or hurricane.The shear above 20' N is tough and has been that way for at least a week now.

I do not know myself if this is what HF and Clark were talking about the other night as the sub-tropical jet.If it is it might be there to stay for awhile maybe they can enlighten us on that.I am not surprised at all by the way things have gone with this system.I am surprised that it might make hurricane strength at best I figured it might go in as a TS.History in the makin pretty neat.
