We may have just seen the first major storm in Southern California, but it has been snowing in the Cascades and Sierra Nevada for weeks now. Visible evidence  shows snow depths increasing above Yosemite Valley.

What we know, what we don’t, and WHY you should care!

I show how this years Pacific water temperatures compare to the 1982 and 1997 events and highlight the kind of weather episodes that these stronger El Niño’s tend to bring.

If you like the blog you will love the book.
