Here comes El Nino!

Latest discussion from the Climate Prediction Center says Nino is coming alright. It's now a matter of how strong will it be?

Looks like we are heading towards El Nino.

Two Types of El Nino Events: Cold Tongue El Nino and Warm Pool El Nino
http://journals.ametsoc.org/doi/pdf/10. ... JCLI2624.1

There are different kinds of El Ninos/La Ninas. They are not all the same.

Should be interesting to see if we get a CT El Nino this year. Those typically bring the harshest Winters.

1972-73
1982-83
1997-98

Interesting..... I thought I might draw a correlation between those values, the type of Winter HGX had and the type of El Nino, but I'm not seeing much.

With the PDO tanking this year and El Nino, I was thinking we might see a repeat of one of these.

How is Lake Travis doing these days? We saw some amazing pics last summer of the lake at very low levels.

Yeah, the incredibly low level of the lake last year was indeed amazing. A person could really get good perspective of it from the air if your flight path took you over the lake.

Last I saw, Travis was sitting at 640 feet. That is actually roughly 10 feet LOWER than last year at this time and 40 feet below the full pool level. The recent rains of this week were mainly I-35 corridor and east which doesn't help Travis all that much.

Things are warming up again. Looks to be this El Nino is going to be more of an eastern type, unlike the last El Nino of 2009-2010, which was El Nino Modoki.

How does that affect Houston?
