Looking at the airflow, If a depression is going to develop, the best spot appears to be further back. say 60W 18N or so. Of course the spin is still evident on PR radar, but I think the main action will be further to the east and North of the current low. The biggest question for me is, will the energy continue to transfer west into the massive blob of convecion (that is unorganized but still fairly presistant). I'd say you might see something popping up in 12 - 24 hours east of PR.

The southern track looks like it's still stifled for moisture, so I think it'll kinda trek along for a while doing a whole lot of nothing.

Of course, I've been wrong before....In fact I'm usually wrong so
expect a hurricane south west of PR in 36 hours

(I kid, but it sure feels like you should expect the opposite of what I think)
