All is falling into place for the waves to begin to organize and the MJO is one of them as shown in the link.The wet phase is now in the atlantic as shown by the green lines and that combined with the pattern setup of the atlantic ridge and the less subsidence in the atlantic so now let's wait to see if the peak of the season will bring the usual systems at this time or atlantic will continue quiet.

But I see a definite pattern change and will will see developments very soon as some models are showing.
