UN agency: El Nino could appear by October

GENEVA (AP) — The U.N. weather agency says there is a "moderately high likelihood" that El Nino — the weather phenomenon that brings above normal rainfall — will develop, but is likely to be weak if it does.

World Meteorological Organization spokeswoman Clare Nullis told reporters Tuesday that experts believe El Nino could begin in September or October and last through year-end. However, the WMO says that neutral conditions could also remain.
