This was what I meant by a “rapid switch to west based” The La Nina is Starting to look EXACTLY how I pictured it looking in July.
The La Nina, after this brief weakening trend, should cool further in N4/N3.4 regions, while N3 and N1-2 Have already Hit their peak


But isn't this just the temporary surfacing of the cold anomalies in these regions that lead to a warming? I think this is temporary. I personally think this La Nina will be more basin wide than anything. Perhaps I could be missing something though.
It can be basin wide, but have a westerly dominance. Overall, it appears to be going according to plan
