I think the shear may increase a bit, but I'm not in the poo-poo camp either. I noticed the 12z GFS looks better in terms of not opening it up to a wave now.  If you look at all the guidance, many models are above 50-60kts which may be telling. Of course hurricane intensity is difficult to determine, but I think writing it off as a garbage 40kt TS is wrong.

think NHC is pretty spot on for intensity and direction

I agree.

 

Earlier I questioned the apparent acquiescence to weak sauce solutions...almost like a defense mechanism.

I don't see why that should be favored.

I would say that there is a developing area of vorticity underneath 5-10 knots of shear and over 31C water temperatures over the western Bahamas and flaring pretty deep convection currently.  Though satellite imagery suggests no low present currently if it can sustain convection I could see possible development.

I see further signs of development with Erika currently.  Southern inflow is strengthening, convection is starting to fire up on the whole eastern side of the circulation and to the southwest of Erika the inflow is starting to fire up convection over the Leeward Islands.  I think Erika will fight the shear off and intensify north of PR.

I'd like to see the low level center more centered under the deep convection.

12z GFDL shows a monster 125-130 knot hurricane in 5 days sitting over the Gulf stream or just south of it over 30C waters and wind shear is being buffeted by a large upper level anticyclone.  This is major problem as a large ridge replaces the troughing over the Eastern US by day 5 and pushes the hurricane back westward towards the East Coast, SNE is still in the zone of uncertainty in my opinion as we are not certain if Erika strengthens rapidly north of the Leeward Antilles.

I think that is reaching....

The Euro now misses the US altogether as it turns north just east of Florida and then right before the Carolinas, it does have a powerful strom east of the Carolinas so sufers all along the east coast would like for that run to verify.
