There's something wrong with the atmosphere because any system in this climatology at that location should be getting strong and growing deep convection at this point. We've all heard over and over that this is the only spot in the Atlantic where conditions are favorable, yet the one system that managed to form here is struggling just like the systems further east.


Just a quick note on "climatology" ... since 1961 (satellite era) the western Caribbean has accounted for 21 named systems in October ... the rest of the basin 63 .... hmmm..that is roughly a 3 to 1 count ... meaning that maybe our concept of climatology is a bit skewed ... :roll:

I have to say I think this system will stay around the Yucatan and BOC for the next week or so, before either strengthening and going N/NE or going into Mexico and trying to form in the PAC.

They have in recent years been forming in the middle to late October

And, there is almost always a storm after the first cold front (the first cold front sometimes spawns the storm


So it wouldnt be impossible to have a Mitch, Michelle, or Lili (1996) type storm form late in October, perhaps from the energy of that first deep trough? I know this is just speculation on my part though.

GFS has me a little bit concerned. GFDL could be rather interesting well down the road if it loops back into the NW Carribbean heading north.

For the record, and really only for the record, the CMC has this move north off the Yucatan in a couple days and become a strong TS in the central GOM. The CMC also shows howling shear across the gulf at this time. These two outcomes appear incompatible.http://moe.met.fsu.edu/cgi ... =Animation

That's just under every other year, right? (21 storms in 46 years) :) How many of those 21 developed in recognized La Nina years?

If you use the years defined by CPC as la Nina ..... 5
If you use the years defined by JMA as la Nina ..... 5

so .... 5 of the 21 in la Nina years

If you use the years defined by CPC as el Nino ..... 5
If you use the years defined by JMA as el Nino ..... 5

hmmm .... seems as though the "true" active years for western Caribbean development are "neutral" years ....

BigA:
I can't speak for prior history but this season the CMC has been worthless.
We have had the CMC put Hurricanes into South Florida repeatedly in 2007.
I remember reading where one of the Pro Mets said that it was not a Tropics model and not to pay any real attention to it.

That's what I meant when I said it was only for the record. I dont put much faith at all in it.

Looking at the latest vis loop it appears to still be offshore and either not moving or drifting NNW. It doesn;t look good at all even though it's still over water.

Looks a little better than a couple of hours ago, but nothing to write home about.

Put things on hold till it re-merges (if ever) over water...wherever that may be.

Yep, goner.

Looks like 95 could be trying to form out in tropical Atlantic, so there's still something going on.

Until then, wake me up when we get something spinning.
