La Nina Has Arrived

As many forecast models predicted would occur, La Nina conditions have now taken over in the equatorial Eastern Pacific. Sea surface temperatures in this region of the eastern Pacific have cooled to 0.7 degrees Celsius below the average. The threshold which defines the onset of a La Nina event is 0.5 degrees Celsius below the average thus weak La Nina conditions are now in progress. The timing of the development of this La Nina is certainly less than desirable, as typically both the number and intensity of tropical systems in the Atlantic tend to increase during La Nina events.
