Niño Region SST Departures (ºC) –  Recent Evolution

During the last 4-weeks, equatorial SSTs were at least 0.5°C above-average across the Pacific Ocean and at least 1.0°C above average in the east-central and eastern Pacific.

Summary:

• El Niño is present across the equatorial Pacific Ocean.

• Sea surface temperatures (SST) remain +0.5 to +1.5 above-average across much of the equatorial Pacific Ocean.

• Current observations and dynamical model forecasts indicate El Niño is expected to strengthen and last through Northern Hemisphere winter 2009-10.
