La Nina- one thing to keep in mind (err several I guess) is that La Ninas don't always last a long time (years). In fact, last year we had a La Nina spring that quickly changed to an El Nino by fall IN THE SAME YEAR. So it is very hard to predict, however, if you can read SST maps (sea surface temp maps), it was evident probably over a month ago that La Nina was starting to look like a strong possibiliy. No idea how long it will last though. Look off the west coast of Chile and look at the SSTs, it'll be clear already. Wacky to have La Nina last spring, El Nino forming in late summer, and now back to La Nina all within about 12 months. Really whipsawing the sealife organisms off the Chilean coast. Not sure if it is related to Global warming, but the ocean currents (globally) are acting a bit strange in last few years IMO. BTW, I'm not a meteorologist or anything like that but did get my BS in Marine Biology. Probably many of you out there know more than I do on the issue.
