Conditions are not ideal right now as there is a trough in the vicinity interacting with the wave.But anything is possible if conditions improve but what is a sure thing will be the rain with some squalls for some of the islands in the lesser Antilles chain.

Yeah true.

Are you back in Culebra?

It is VERY possible that we will have an Invest 91L rather soon...
I have been watching this tropical wave east of the Lesser Antilles since last week and let me tell you that this wave definitely has good potential to become a tropical cyclone over the next 2-3 days.
Over the past few days, the system has been experiencing some moderate westerly flow in the upper-levels. This westerly flow has not been strong enough to totally dissipate this system. In fact, the system persisted well enough in that type of environment. Notice that I said "that" type of environment. That's right...conditions are changing as I type. In fact, at this time, the system is slowly developing a fanning out of convection south of it. This has been impeded by an upper-level low over South America, however, that upper-level low is dissipating and expected to continue doing so. Conditions should improve slowly today and tomorrow, with the GFS is forecasting a very favorable upper-level ridge of high pressure in 2-3 days over the central Caribbean. Unfortunately, if that pans out, this would provide unusually favorable conditions for this wave to continue to strengthen. Combine improving upper-level winds with the words...October, Caribbean Sea, very warm SSTs....and we have trouble.
Even though is kind of early, this system appears to have its eyes over the Greater Antilles. You can see the remnants of the cold front and trough that Wilma left behind NW of Haiti. This trough is forecast by some models to develop a low pressure center and move northward. The flow around this developing low should induce a WNW track for the developing wave east of the islands. Anyone from Puerto Rico to Cuba should watch the progress of this system carefully.
Speaking of the current pattern in the Atlantic...There is currently a HUGE upper-level ridge in the central and eastern Atlantic, which is extremely unusual for this time of the year. If that ridge were in place in August or September (it was not generally the case), we would have seen several Cape Verde storms develop. It is amazing to see such favorable conditions setting up this late in the season. This is the same ridge that managed to provide the VERY favorable conditions for Wilma to bottom out into a historic hurricane. It has moved from the western Atlantic toward the eastern Atlantic over the past several days.
Some people have talked about the wave in the eastern Atlantic. Right now, the wave is vigorous for this time of year, but upper-level conditions are very unfavorable for development. However, this large upper-level ridge NW of it, should provide a more favorable easterly flow as the wave moves westward. If it manages to hold on to its well-defined structure, we could very well be dealing with yet another developing system. I wouldn't bet anything just yet, since it would be a first for a system to develop that far into the Tropical Atlantic this late in the year, but the potential will be there as it moves west.
What an amazing season we're witnessing...

Yeah true.But I dont like the position where it is now in relation to Puerto Rico so we have to watch it closely caribepr.
Are you back in Culebra?
Yep! I got back on Monday - and REALLY happy to be back!
All other bits aside, it was horrendous to not be able to go online and have to watch Wilma and Alpha via cable television. No need to explain more on that one to you.
adding: Yes, I'm concerned as well, but other than keeping an eye on it (and cooking a bunch of food for the freezer, which I did last night since I'll be busy this week), I'll just concentrate on the cart!

That's ok my friend.
From where I am in Puerto Rico watching this wave very closely as by the position where it is I am a little worried here.Yes it resembles a september pattern rather like late october in the tropical atlantic.

I've lived on Merrit Island (once the southern end, once the northern) and love those sorts of days there (dolphins and otters get all excited too). But I'll take Culebra anytime
