Warm water problem

A couple of weeks ago, there was a guy on Landline from (I think) the Bureau of Meteorology talking about a subsurface body of very warm water being tracked West East across the Pacific.  It was thought that if it surfaced, it would be the start of a clear El Nino.  He said it was about 4-5 degrees hotter than average.  I had no idea that large warm, subsurface (about 150 m down) bodies of water were tracked like this in real time.

The subject gets a detailed explanation at this blog post.   I don't know who the author is, but he seems well versed on the subject.  He says it has the potential to be a bigger El Nino than the record setting one at the end of the 1990's.

Let's see what happens....
