Geneva (AP) -- The U.N. weather agency is predicting that the phenomenon known as La Nina is poised to last through the end of this year, a mysterious “triple dip” — the first this century — caused by three straight years of its effect on climate patterns like drought and flooding worldwide.

The World Meteorological Organization on Wednesday said La Nina conditions, which involve a large-scale cooling of ocean surface temperatures, have strengthened in the eastern and central equatorial Pacific with an increase in trade winds in recent weeks.
