I wouldn't totally count on re curvature just yet. Even if we do get a trough/ull in the later period, we probably want to wait and see the how deep the low becomes. If it is weaker, it won't be steered by the upper levels, but will be steered more by the mid level steering layer.

If the NHC is forecasting a weakening system late in the forecast period... I wouldn't be suprised if the system gets pushed back westward to the north of the islands.

I doubt it will take that far of a northerly course if it doesn't actually develop into something soon.

Seems that GFLD loves the islands since 3 or 4 consecutively runs....hope it will fish quickly for those who lived in the islands :double: :spam:

GFDL is just pointing out that there won't be much of a system once it gets to the end of that track......if it gets to the end of that track!

Exactly my point this is forcasted by most if not all models the conditions in front of this depression are not good for significant intensification.

Let's see, number of named storms since Dean (prior storms were mostly really subtropical) 5. Number of landfalling storms 5. That's 100%, maybe it's time for a fish. And I'm glad our yearly threat is already over (a whimp if I must say). But I'll still be a little nervous for the next month. The 06z gfdl did take this south but it also dissapated it too.

Probably runs into that high shear that is forecasted. Interesting to see the GFDL also slows down the depression to 3.7kts at 6hrs, which should be about now. Will be interesting to see the strength forecast from the GFDL and also to compare it to the SHIPs forecast.

Interesting, the SHIPS don't see the shear being high enough to weaken the system ,rather just high enough to effectivly halt the development of the system after 72hrs, seems pretty reasonable actually.

I haven't been paying that much attention to TD #8 today; I've been focused on Humberto for most of the day but I did take a look at some of the models on TD #8 just a while ago and it looks like it could turn out to be a fish storm. Would that be a pretty accurate statement on TD #8's status this evening? Feedback anyone?
