Peru said El Niño threat over, waters cooling and fish returning http://news.yahoo.com/peru-says-el-nino-threat-over-waters-cooling-232314417.html
And… El Nino master blaster Bob Tisdale said in his part 12 update –
For an El Niño to form, the ocean or atmospheric portions must both cooperate.
But, referring back to Figure 11, we’re definitely not seeing a comparative weakening of the trade winds this year, and there have been fewer
westerly wind bursts than there were in 1997. The additional westerly wind bursts and the continued weakening of the trade winds are what
drive additional warm water from the western tropical Pacific into the eastern equatorial Pacific, thus reinforcing the development of the El Niño.
Those are the additional feedbacks that are absent so far this year.

>>Climate models surveyed by the Bureau continue to indicate that El Niño is likely to develop by spring 2014
The Bureau’s ENSO Tracker remains at El Niño ALERT,
indicating at least a 70% chance of El Niño developing in 2014. <<

Update
El Nino chances fading says BoM Models21.10.2014 09:37 Age: 1 day
Computer models used by Australian Bureau of Meteorology (BoM) suggest that the emergence of the expected El Nino Pacific Ocean warming event is becoming less likely.
Only three of the eight computer models surveyed by BoM indicate the possibility of ocean conditions reaching El Nino thresholds by the middle of the southern hemisphere summer, with the remainder favouring persistence of neutral conditions, according to the latest summary of the prospects for a potential El Nino issued by BoM today (Tuesday, 21 October, 2014).
This compares with the situation just two weeks ago in the previous BoM report (issued on 7 October, 2014) when six of the eight models indicated the possibility of ocean conditions nearing El Nino thresholds by early southern hemisphere summer.
BoM reports that indicators for the so called El Nino–Southern Oscillation (ENSO), the cyclic system of warming and cooling seen in the Pacific Ocean, as well as patterns of Australian rainfall, “continue to show some El Nino-like signatures, but they remain in the neutral range”.
