Re: SW Caribbean development next week?
The AccuWeather free site notes today that a weakness will persist in the area from the western Caribbean to the Bahamas into June and that we may see more potent development after the system progged to develop near the Bahamas.

Re: SW Caribbean development next week?
Below is a discussion by Dr Jeff Masters of Weatherunderground about the Caribbean area.
Potential serious rainfall threat to Haiti next week
Long-range forecasts from the NOGAPS model, and to a lesser extent, the ECMWF and GFS models, continue to predict an increase in moisture and decrease in wind shear over the Western Caribbean 4 - 6 days from now, leading to development of a tropical disturbance with heavy rains in the Western Caribbean early next week. A strong subtropical jet stream over the southern Gulf of Mexico will steer the disturbance to the north and east, and the potential exists for heavy rains of 3 - 6 inches to affect eastern Cuba, Jamaica, Haiti, and the Dominican Republic in the Tuesday - Thursday time frame next week. It is possible that a tropical depression could form from this tropical disturbance, though most of the models indicate that high levels of wind shear will make this improbable.

Re: SW Caribbean development next week?
Luis, I'm no expert but I do think that watchful waiting is prudent here. Those who would dismiss potential development could be in for a surprise. Also, once the ice is broken by the birth of the first storm, hold onto your hat because I think we're in for a wild ride over the coming months.

Model Rundown

GFS likes the EPAC development

Nogaps is a little scary, especially for usually being a conservative model

Yucatan low has spun up a little tighter than it was yesterday but is being sheared a good bit and more shear is forcast in that area.

The Bahamas low not much better.

Quite obvious spin on the Yucatan system, shear is high but if it gets a brief window then we could well see an invest out of this eventually.

Re: SW Caribbean development next week?
Shear is too strong for any development IMHO. We will need to wait another few weeks for significant development in the region.

Shear is indeed quite strong, can't ever rule out a circulation however, esp if there is ever a quick reduction of shear at any moment...that being said I think the E.coast system has a better shot anyway of developing, at least in the medium term...

Re: SW Caribbean development next week?
I don't believe the Yucatan low is what the models are developing. The models generate the advertised low in the deep SW Caribbean where shear will be lower, this is where it will have the best shot

18z NOGAPS
This model by far has been the most agressive on intensity.
