There is little to no remaining signal of the El Nino. SSTAs, subsurface temps, trade winds, and ocean height are all neutral now. SOI is the only parameter that's still in El Nino mode, but even then, it too, is edging closer to the normal mark as I speak.

So will LaNina become more prevelant now??? Thanks

Based on the analyzing over the past several months, it does appear we will see the arrival of a weak La Nina before the year's end. If the tongue of cool temp anomalies at a depth of the equatorial Pacific rises and spreads to the surface quick enough, we may see La Nina as soon as summer begins. On the other hand, there is still a slight chance the warm anomalies will rebound, delaying the development of La Nina to early next year. Will it form in time to influence the hurricane season? While evidence is starting to point to 'yes', I cannot say with 100% certainty just yet.

ROB, Thanks for the Info ..

Very interesting stuff... Thanks for all the data and information!

No problem.

Another interesting feature is the warm SSTs from the equator 15 degrees south (-15) off the African Coast. For the last several years there has been a very narrow band (to -10S) of warm SSTs from Africa westward along the ITCZ. This year it seems the warm waters are much broader, south beyond -15 degrees and westward. Let's see if this has an effect on the Cape Verde season. It should assist in the lowering of SLP in the east Atlantic, providing a more northward and robust ITCZ, and a weaker/more northward placement of the Azores high. 8)

Hmmmmm... that's interesting, Steve! Do you think this feature will make it more of an active season?
