There is a wave that looks great. Nothing on it but in the mid Atlantic it has some spin and plenty convection.

At first glance, I thought that arrow pointing to Fred on the 18z surface analysis was a new, and oddly tilted, tropical wave:

My thoughts exactly!! I thought it was a high-amplitude, negatively tilted wave that somehow had its axis extending all the way into southernmost Venezuela.
