I know enough about this phenomenon to know when it does not look good. While no one has singled me out as being a "it's over Jim" poster, I must say, the writing is on the wall here for the FUTURE of this system. And as for now, it does look terrible. When the westerlies dip down like we are seeing them forecast on the models, that is a bad sign for tropical cyclone development. I for one will be very surprised if this ever develops in to anything that anyone will ever need to be concerned about. That is not the same as saying it is finished and we should not pay attention to it.

I do think that some posts from time to time from some members are negative on purpose, for what ever reason. But I assure you all that mine are at least backed up with some science or model support. As I said earlier, no one would be more thrilled than I to have a hurricane out there- but I have to realistic, that does not look likely from TD8 this morning or in 10 mornings from now.

No one said "never". They never said that ;-)

And, Derek did not say that they should stop writing advisories. He said something about people might be debating that on this board- whether or not to continue with writing advisories.

Gotta read the posts thoroughly before rolling people under buses.

As long as the TD can stays strong till it can get though the hostel environment then it may be able to get isn't stuff together.
Mark said yesterday that there was going to be some big shear going on. We just have to wait a few day and see what it does. Maybe a few day like this. I knew yesterday something was going on cause the didn't bring it up to TS. I think they seen this coming.IMHO

The point is the future is not bright for TD8 as of now.Forcasted by most or if not all the models.

Looks like shear will make this weak and west into the eastern carribean where it will make a strong comeback at a higher LAT than Dean or Felix. Still maintaining a nice classic "S" shape as a depression or wave.

Once again note that I can't rememberone model showing shear increasing today, even from last nights models...yet another example of just how poor the models are when it comes to dealing with shear with systmes like that. Its got a good circulation still which is something 92L didn't have when it did the same thing and as we saw with 'Gabby' these circulations can stay intact for a good 2-3 days without any convection at all.

Well said sir ... taking comments out of context easily turns a depression into a storm

You in NC or TX or LA today ?

Wind shear is about 10 knots over TD 8, and is forecast to remain below 10 knots through Saturday morning, which should allow TD 8 time to grow to a modest tropical storm. Later on Saturday, the models now unanimously agree that TD 8 will encounter hostile upper-level westerly winds. The high levels of wind shear these upper-level winds will bring are likely to seriously weaken the storm, and may be able to tear it apart. It appears likely that TD 8 will pass north of the Lesser Antilles Islands, sparing them its strongest winds. Should TD 8 survive past Monday, it may represent a threat to the U.S. East Coast.

The NOAA Hurricane Hunters are scheduled to fly a research mission into TD 8 tonight.

Looks like Td 8 has slowed to a crawl , doesnt want to head into that shear

I never said that adviories should be stopped now... I said that the dialogue on whether to consider stopping advisories should begin

if this continues into the afternoon, then discontinuing advisories would be a legitimate decision

Mind you Derek while it is being sheared it has still got some convection on that southern side and as long as it can keep that LLC then they won't downgrade this while its still got that, countless times they kept a naked swirl as a TD for 24hrs!
This one isn't quite naked...yet anyway!
I think if shear can ease off again then this could get going pretty readily, its got decent structure, just a very sheared convective apperence.

They had to go ahead and task the flights.....regardless of what the system is doing right now. Obviously the NHC is still of the belief that there may be some strengthening before the shear job.

I suspect if this trend continues those flights are likely to be called off.

I wouldn't be all that surprised Drew if this shear currently is as strong as the stuff the models have been showing for the future, indeed this may well be one and the same feature and the models simply didn't expect the shear to dig this far south yet?
