   We deliver climate prediction, monitoring, and assessment
products for timescales from weeks to years to the Nation and the
 global community for the protection of life and property and the
                  enhancement of the economy.

La Niña and Seasonal Outlook
               Niño Region SST Departures (oC)
                      Recent Evolution

The latest weekly SST departures are:
Niño 4          -1.2ºC
Niño 3.4        -1.3ºC
Niño 3          -1.5ºC
Niño 1+2        -2.0ºC
       Sub-Surface Temperature Departures (oC)
               in the Equatorial Pacific

                         • Since May 2010, negative subsurface
                         temperature anomalies have dominated the
                         central and eastern equatorial Pacific.
                         • The most recent pattern of subsurface
                         temperature anomalies is similar to those
                         observed since mid September 2010.


                             Most recent pentad analysis
         Pacific Niño 3.4 SST Outlook
• Nearly all models indicate that La Niña (Niño-3.4 SST anomalies -0.5°C or less) will
persist at least into the Northern Hemisphere spring 2011. Just over half of the models
indicate La Niña will strengthen further and peak during the Northern Hemisphere early
Winter 2010-11.

SST Outlook: NCEP CFS Forecast
   Issued 14 November 2010

           The CFS ensemble mean (heavy blue
           line) predicts La Niña conditions into
           Northern Hemisphere summer 2011.
