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


*African Monsoons:*

Moderate to heavy rainfall resulted in moisture surpluses over many areas
of the Sahel region of West Africa and partial areas of the Greater Horn of

Week-1 outlooks call for an increased chance for above-average rainfall
over central Mali, Burkina Faso, western and southern Niger, northern
Nigeria, and western Ethiopia. In contrast, there is an increased chance
for below-average rainfall portions of Senegal, The Gambia, Guinea-Bissau,
eastern Sudan, and South Sudan.

*Asian-Australian Monsoons:*

For the past 90 days rainfall amounts are showing a mixed pattern over the
monsoon region with slightly deficient conditions over parts of central
western India, particularly the state of Gujarat,  and central eastern
India, southern peninsular India, central China, Koreas, Japan, and parts
of Papua New Guinea, but above normal elsewhere particularly the Indonesian
archipelago and the Philippines. For the past 30 days the rainfall
situation was also a mixed pattern with highly deficient rainfall
conditions over east central India, central and eastern China, Thailand,
Malaysia, and Japan. Elsewhere, rainfall was at generally at near normal or
above normal levels.

In this past week, monsoon rainfall was generally below normal over  much
of monsoon region except for parts of central India and Laos. According to
the India Met. Dept. (IMD), as of today, for the 2016 monsoon season so
far, since the 1st of June, the monsoon rainfall has been near normal  by
about -2 % across the country. A pair of  active tropical storms Lionrock
and Mindulle is threatening coastal Japan.  In the next couple of weeks the
NCEP GFS is predicting a mixed rainfall pattern with below normal rainfall
over northern India, southern and eastern China.

*North American Monsoons:*

Above-average rainfall has been observed over much of Mexico during the
past week.

Rainfall accumulations over the past 30 days were near-average for
southwestern U.S. and above-average over northern Mexico.

NCEP/GFS Forecasts call for above-average (below-average) precipitation for
northwestern Mexico (Arizona) during 22-28 August, 2016.

*South American Monsoons:*

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