I warned about the potential of tropical cyclone development in early June just a few days ago- it looks like that threat may be materializing. The placement of these anomalies indicates that this would indeed be Phase 8 of the MJO. However, the GFS may be taking this MJO wave too quickly to Phase 8.
After looking around other model solutions, it certainly still looks like the threat for tropical development (either in the East Pacific or Caribbean) is a logical one. I will monitor this threat closely over coming days and weeks and wil update as is needed.
