La Nina strengthen during August 2010, as negative sea surface temperature (SST) anomalies reached at least 1 deg C across most of the equatorial Pacific by the end of the month. It was noted that there was a enhancement of the low-level easterly trade and anomalous upper-level westerly winds over the western and central equatorial Pacific. What all this means is that oceanic and atmospheric anomalies reflect the strengthening of La Nina.
Nearly all models predict La Nina to continue at least through early 2011. However they disagree on the eventual strength.
Will continue to update La Nina conditions each month into the fall and winter of 2010-2011.
La Nina supports a active northern storm trace that would enhance precipitation over Idaho and northern Utah.
