GENEVA, Sept 1 (Reuters) - The current El Nino weather
phenomenon is expected to strengthen before the end of the year
and to peak between October and January, the World
Meteorological Organization said on Tuesday.
Climate models and experts suggest surface waters in the
east-central Pacific Ocean are likely to be more than 2 degrees
hotter than average, potentially making this El Nino one of the
strongest since 1950, following similar weather events in
1972-3, 1982-3, 1997-8.
