Thankfully it appears to be spurious. Watch that stream of vorticity off Venezuela - GFS has a tendency to spin up systems from that thing for some reason. It's good entertainment though![]()

Might be from a low-latitude wave. I think the GFS did this a lot last Oct/Nov, when the ITCZ was so far south that every wave ran over northern SA when entering the Caribbean. Regardless of whether the source of that vorticity is legitimate or spurious, the incoming MJO is probably getting the GFS all excited.
Also a powerful CCKW that is expected to arrive next week as well.
