First signs of the possibility of a La Nina in the Boreal autumn,
or winter, IMO.

But the CFS.v2 forecast in that pdf is predicting an El Nino.


It predicts ENSO neutral throughout, with variations during the
period. it never escapes -0.5 - +0.5. I watch the changes from week
to week and the probabilities, on the bar graph. Distinct tick up in
the probability of La Nina this week - TBF, nothing but ENSO neutral
showing, just yet. but these changes always start somewhere. We'll
see.


The particular prediction to which I was referring is on page 25 and
shows the anomalies dropping below -1.0 from ASO. However, I've also
been watching this product for a long time and suspect that rolling a
die would work just as well. :-)

A fairly strong La Nina now very likely through the boreal autumn and winter. Should drop global temperatures. It'll be very interesting to see by how much.
