Strong Mid Level shear over Ernesto

I dont want this getting buried under the drivel
Look at the SW mid levle shear from a mid level anti-cyclone displaced to the east. Today, Ernesto has experienced about 20KT of mid-level shear and as we saw just a couple of days ago, ML shear is extremely destructive

I wonder how much of that is due to circulation of Ernesto itself... I mean, you'll often see objective maps analyze decent shear on the periphery of a hurricane owing to the cyclonic-anticyclone lowlevel - upperlevel flow almost always present at the periphery of hurricanes. Of course, lowlevel flow is convergence cyclonic, while upperlevel flow is divergent anticylonic, so there SHOULD be perceived shear on hurricanes, particularly along the edges where satellite estimates may be able to gauge low-level flow better.

However, what this may have done is reduce the chances of a major cane in the GOM
maybe Derek but the speed it is going combined with extremely warm SSTs AND the fact it may not even be over land that long if it slips between Hispaniola and Cuba could still be a major cane.
I'm calling for it to reach major cane status before landfall in the US still.

This is mid-shear, which isn't much amplified by hurricanes.

You couldn't possibly see this mid-shear underneath the convection.
That said, it looks to me like this is *just* SE of Ernesto and he's not doomed yet. Just a little more though, and it's goodbye.

I agree, there's too much against this now for it to reach cane status. You can almost guarantee that this strength forecast will be coming down on the next advisory. If it hits Cuba as a tropical storm and not a hurricane, then it's over for sure...Cuba would only weaken a hurricane, but it would destroy a tropical storm. Central Florida still may get a tropical storm out of this though, because even if it weakens to a wave, there's still a chance it can get another LLC together and form into a tropical storm before hitting Florida, but that's a big IF.....This is fantastic news though!!! Hopefully all of the hype on this storm will be going away soon....
I will say that if by chance it manages to re-strengthen to a hurriane before hitting Cuba, then a weak cat 1 cane IS still possible for central florida....
