This wave coming off Africa looks to be building some rather impressive ordinary convection already, though there aren't signs of rotation yet:

I checked the models. Most of them strengthen or maintain the wave across the Atlantic, but then the models aren't very good at predicting unformed cyclones.

I also checked the SAL - it seems quite weak right now out in the Atlantic, and quickly dispersing:

The biggest problem looks to be wind shear in the basin. It isn't super strong, but it is there:

This is one wave to watch in my mind.
