The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems have been updated on the CPC Global Monsoons


*African Monsoons:*

Portions of West Africa received above-average rainfall. Rainfall was also
above-average across many places in the Central Africa countries, extending
into South Sudan, western Ethiopia and southern and eastern Sudan.

Week-1 outlooks call for an increased chance for above-average rainfall
across Guinea, Sierra Leone, Liberia, western Cote d’Ivoire, southern Mali,
Burkina Faso, parts of northern Ghana, southern Niger, northern Benin,
northern Nigeria, western Ethiopia and western Kenya. In contrast, there is
an increased chance for below-average rainfall over eastern Cote d’Ivoire,
southern Ghana, southern Togo, southern Benin and southern Nigeria.

*Asian-Australian Monsoons:*

For the past 90 days rainfall amounts are showing deficits to various
extents over large parts of central and western  India, and large deficits
over southeast Asian countries such as Thailand, Laos, Vietnam, and
Cambodia, and the Philippines.  However, northeastern India, Burma, coastal
southeastern China and many parts of Indonesia received  above normal
rainfall. For the past 30 days the rainfall situation was deficient over
central India, coastal Western Ghats, Thailand, Laos, Cambodia, the
Philippines islands and parts of New Guinea. However, coastal eastern
India, northeast India, Burma, and parts of southeastern China and
Indonesia had received more rainfall.

In this past week, monsoon rainfall is generally deficient across central
India, eastern Asian countries, Indonesia, central eastern China, and
Japan. According to the India Met. Dept. (IMD), for the first fifteen days
of June, the monsoon rainfall over India has been deficient by 25 % across
the country. In the next couple of weeks the NCEP GFS model is predicting
mostly below normal to normal over much of India and much below normal over
southeastern China in the first week, and a return to better conditions in
the second week.

*North American Monsoons:*

Above-average rainfall has been observed over southwestern Mexico during
the past week.
Rainfall accumulations over the past 30 days were below-average over
central and southern Mexico

NCEP/GFS Forecasts call for below-average rainfall across eastern Mexico
during the next two weeks.

*South American Monsoons:*

The annual summary for the 2015-2016 South American Monsoon wet season is
available on the CPC website at:
