It's best chance for development may not come for another 7-10 days if it reaches the NW Caribbean or nears the Bahamas.



I guess we'll have to look to that absolute MONSTER of a wave(soon to be storm) coming
off of Africa then....

Its biggest challenge will be the sal that is to its north. what to watch for is if convection can increase some more then the nhc will likely increase chances more.

It certainly doesn't have the look of a developing TC on MIMIC-TPW imagery:

I am wondering what that is that hits Texas. Are there any other models showing this?

most likely due to its relatively small size. the resolution is not that great on there.

only time will tell.

Isn't this thread for 92L? This model chitchat involving a moderator needs to be taken elsewhere.

The "chitchat" was in reference to a NOGAPS model run involving 92L. There were several posts which included a moderator (i.e. me) about an additional feature and, as you can see, whatever conversation about that additional, non-92L feature that existed has ended.

If additional mention of non 92L features in a model run appear and persist, we (moderators) will encourage that discussion to move to a more appropriate forum.

I'd say 40-50% probably is a good estimate right now. That being said I think its going to struggle to go much further then what it already has.

GFS weakly develops it but kills it off totally in the Caribbean, conditions don't look great past 50-55W above 15N.

I think the conditions may be much more moist in the Carib if this invest can make it that far... The dry conditions in the carib have gone on far too long and they aren't going to stay that
way forever.

2 PM TWO:

A LOW PRESSURE AREA ASSOCIATED WITH A TROPICAL WAVE LOCATED ABOUT
750 MILES WEST OF THE CAPE VERDE ISLANDS HAS CHANGED LITTLE IN
ORGANIZATION DURING THE PAST SEVERAL HOURS. ENVIRONMENTAL
CONDITIONS ARE MARGINALLY CONDUCIVE FOR GRADUAL DEVELOPMENT OVER
THE NEXT COUPLE OF DAYS. THIS SYSTEM HAS A MEDIUM CHANCE...30
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS
AS IT MOVES WESTWARD AT 10 TO 15 MPH.
