delta is finally accelerating to the east-northeast. it's still firing deep convection, but should be under progressively greater shear and lower ssts, so the tropical nature of this system is not going to last much longer. interesting that some of the moisture will end up sweeping onshore in morocco and the western sahara autonomous region... that's rather vince-like in its abnormality. the surface center will have probably decayed by then, unless it becomes the dominant feature of the extratropical shortwave diving down to pull the storm out. could just be a sheared-off moisture plume by then.
for the last few days the globals have been handing off energy to another system to the west of delta--it is forecast to rapidly spin up as another kink of upper energy cuts off southwest of the block in the north atlantic. most show it moving southwest for a spell, then lifting north as the heights to the northwest begin to fall. in other words, it's doing the same sort of cut-off stunt as delta just did, more or less. these things sometimes hybridize into tropical systems, but i will say that this one doesn't have the same model look as delta did--it's chances of converting aren't nearly as good as delta's were. this is 2005, though. nothing is impossible.
