La Nina likely to develop in coming months
"These conditions are more likely than not to strengthen into a basin-wide La Nina over the coming months."
The WMO said however, that "the timing and magnitude of such an event in 2010 are as yet uncertain."
La Nina is the opposition condition of El Nino. It is characterised by unusually cool ocean temperatures in the eastern equatorial Pacific. In late 2008, it was blamed for icy conditions that claimed dozens of lives across Europe. The weather phenomenon can also bring about strong rainfall in Indonesia, Malaysia and Australia, as well as drought in South America. El Nino, meanwhile, is characterised by unusually warm ocean temperatures in the central and eastern equatorial Pacific.
