Nothing is going to happen quickly with this system, and I'd look farther south around 13N-14N (as Derek stated earlier today) for the beginnings of any are of low pressure. That's where all the models initialize development, not up in the northern Caribbean. There's definitely no low there now, and certainly not up north of 15N, all the turning you see up there is just flow around the wave axis (southeast winds east of the axis, northeast winds west of the axis). Lowest pressure is just north of Panama.
Even though there appears to be a lot of model agreement, that doesn't mean they're right. Development chances aren't high yet. I'd say maybe 20-30% at most. That's still a 70-80% probability of no development. 12Z Euro is slower and farther south with any possible track, indicating a threat to northern MX or south TX late next week. Canadian is not even worth mentioning for tropical systems, neither is the NAM. NOGAPS has been a poor performer for years as well. Right now, I'm paying closest attention to the ECMWF, though the GFS isn't too much different from the ECMWF.
As for potential intensity - IF this system becomes a TS, then the slow movement blocked by the ridge is the perfect setup for rapid intensification to hurricane strength and beyond. I don't see any inhibiting factors if and when it gets spinning.
