La Nina, a weather phenomenon usually linked to heavy rains and flooding in the Asia-Pacific and South America and drought in Africa, has re-emerged and is likely to persist into early 2012, the World Meterological Organization (WMO) said on Thursday.

However, it is "very unlikely" to reach conditions as strong as those of the 2010-2011 La Nina event that ended in May, the United Nations agency said.

"This La Nina is expected to persist through the end of this year and into early 2012, possibly strengthening to moderate intensity," the WMO said in a statement.

El Nino, its opposite weather phenomenon which warms the Pacific, has been ruled out as occurring before April 2012, according to the agency whose assessment is based on input from climate prediction centers and experts around the world.
