Some very interesting goings on...
Firstly it appears as if movement is actually towards La Nina now rather than El Nino but at any rate we will be seeing a close to neutral Pacific setup.
The AMO is pretty high, the tropical Atlantic is really heating up.
Great video...

.......
Perhaps most interesting though is the predicted forecast of the MJO in around 20 days forecast to be a high amplitude phase 7/8 wave which in the first ten days of June could lend itself to an early start, infact both the GFS and GEM ensembles have both gone for some south Carribean activity and the GFS operational tonight actually went bonkers (encouraging to see this early though)...
I would also add that looking at the data i have high optimism for this hurricane, especially a more USA prone pattern.
