I have been following what looks like a weak LLC near 8N/42W out in advance of the main wave axis and MLC near 10N/40W today. It's clear that the disturbance is moving very quickly, so quickly that it will likely have a hard time organizing over the next 3-4 days. By "hard time" I mean that it will probably remain as it is, or perhaps weaken a bit.

Once it reaches the eastern Caribbean in 3-4 days it may experience increasing wind shear, another minus for development. That shear may not abate until if/when it reaches the western Caribbean in another week or so. But it's way too early to tell if it'll just skirt across Central America and enter the Eastern Pacific or possibly be far enough north to reach the Yucatan. My estimate would be most likely a track toward Belize then possibly the southern BoC, but that's a very low confidence forecast.

There could well be a chance for development next weekend if there's anything left of it when it slows down and convergence increases in the western Caribbean.

As for a model to follow, I'd look at the BAMS (shallow-layer BAM), which the NHC doesn't publish to the public, as this is a low-level system.

One final factor to consider is that I scheduled July 3rd off as a vacation day. So that pretty much seals the deal. ;-)


so your going to just ignore the models and say its not going to develop right away? the models bring it up to 30kts with in 12 hours and 70mph about with in the next 120 hours


Models are not to be ignored, nevertheless, they are not supposed to be taken seriously when a system is developing. So far there is nothing close to a depression.

Chris is merely using the models properly

SHIPS assumes we already have a TD, which are are currently as close to a TD as we are of Mickelson winning the PGA Tour driving accuracy category

Also, the globals are not overly indicating development

Not lookin too bad tonight for a weak low level circulation. Maybe it'll slow down a bit and allow the wave behind it to catch up.

Yeah, what HE said! ;-) Those would be the same models that had 91L a TS hitting Florida today?

That's not "models" it's "model" - the SHIPS intensity scheme.

Do not take intensity forecasts from either it or the GFDL particularly seriously for INVESTS..of far more value is whether you see an organized storm form on a variety of global models like the GFS, ECMWF, when looking at whether an INVEST may intensify.

Storm-specific Intensity forecasts have enough trouble with named systems; for INVESTS their value is pretty nil.

According to this map, the system should start slowing down tomorrow before it reaches the Islands:

I don't understand why you guys keep saying it is gone..

Please explain to me what is gone.

In my daily discussion I did say that the overall shear/Sal is fairly faverable. But the window is very small about 36 to 48 hours before it moves into higher shear. The shear zone over the caribbean should spread into the eastern caribbean by 36 hours. Which appears to make it very unfaverable for this system. There is a slight chance but overall the system is at 7 north/45 west...In has a weak LLC/MLC with some convection. Only a few or maybe one has ever formed east of the islands in June(If I remember right)

GFS shear forecast for hour 120 would put the caribbean in favorable conditions as far as that is concerned.

I would trust the model shear forecast about as far as I can eat cake. The shear models are not very good at all. Worst then the Hurricane models wxman57 was talking about. I expect the shear zone to keep moving slowly eastward over the caribbean. But thats for the 24 to 72 hour time frame. After that it is spiting in the dark when it comes to shear.

I can eat cake pretty far! Parcitularly if it's chocolate! So, what does that mean? I think it means time for bed. Night, all....

anyways, back to business...it appears convection maybe reforming...banding features are coming back. Check out this loop

no mention of it in the latest TWO but I had a strong feeling it would be an invest - lets see if the 5:30 TWO mentions it.

Nevermind - just saw it mentioned....looks like they dropped the Bermuda system. :wink:

A SMALL AREA OF LOW PRESSURE IS LOCATED ABOUT 1150 MILES EAST-
SOUTHEAST OF THE SOUTHERN WINDWARD ISLANDS. THERE IS LITTLE
SHOWER ACTIVITY ASSOCIATED WITH THIS WESTWARD-MOVING DISTURBANCE AND
SIGNIFICANT DEVELOPMENT IS NOT EXPECTED
