In a stunning turn of events, the El Nino disappeared from the charts last week. I did think that this was only temporary, and that the next update could bring back the El Nino warm water anomalies. However, after the most recent update, it is apparant to me that this is an actual issue, and that the El Nino may be starting its painfully slow demise.
You may notice warming in Nino region 4. Beware, Region 4 is notorious for giving false warmings and cooling that may be nothing more than simple warming. If you want to see the El Nino, watch for warming in at least Region 3.4 and do not rely on Region 4- that solution does not end well.
