WMO has issued its latest El Niño/La Niña Update on the phenomena in the tropical Pacific which have important consequences upon weather and climate around the globe.
The Update summary says:
- Weak to moderate La Niña conditions have prevailed since around October 2011;
- La Niña conditions are expected to persist until March to May 2012;
- Currently, expectations beyond May 2012 are uncertain. While neutral conditions appear likely, possibilities for development of El Niño, or even redevelopment of La Niña cannot be ruled out.
The situation in the tropical Pacific will continue to be carefully monitored. More detailed interpretations of regional climate fluctuations will be generated routinely by the climate forecasting community over the coming months and will be made available through the National Meteorological and Hydrological Services.
