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

*HIGHLIGHTS:*



*African Monsoons:*



Moderate to heavy rainfall sustained moisture surpluses over
Guinea-Conakry, Sierra Leone, Liberia and southwestern Mali, whereas
suppressed rainfall prevailed over many places in the Gulf of Guinea and
Central African countries.



Week-1 outlooks call for an increased chance for above-average rainfall
over southern Guinea-Conakry, Sierra Leone, Liberia, portions of South
Sudan and western Ethiopia. In contrast, there is an increased chance for
below-average rainfall over southern Senegal, Gambia, Guinea-Bissau,
portions of northern Guinea-Conakry, southwestern Mali and northern DRC.



*Asian-Australian Monsoons:*



For the past 30 days the rainfall situation was deficient across central
and southern India, parts of central China, Thailand, Laos, Cambodia, the
Philippines islands, parts of New Guinea and sporadically across central
and southeastern China. Elsewhere, rainfall was at near normal or above
normal levels. For the past 30 days the rainfall situation was deficient
across central and southern India, parts of central China, Thailand, Laos,
Cambodia, the Philippines islands, parts of New Guinea and sporadically
across central and southeastern China. Elsewhere, rainfall was at near
normal or above normal levels.



In this past week, monsoon rainfall is generally deficient across  India
except along the coastal western Ghats. Weekly rainfall was also deficient
over Malaysia, and parts of Indonesia.   According to the India Met. Dept.
(IMD), for the first twenty nine days of June, the monsoon rainfall has
been deficient by 12 % across the country.  In the next couple of weeks the
NCEP GFS model is predicting more rainfall over parts of central and
northern India, Burma, and Thailand, but below normal rainfall over the
other regions especially along the peninsular southern India and the
coastal western Ghats region.





*North American Monsoons:*



Above-average rainfall has been observed over northwestern Mexico and
southwestern U.S. during the past week, while drier-than-average conditions
continued across central and southern Mexico.



Rainfall accumulations over the past 30 days were below-average over
central and southern Mexico.



NCEP/GFS Forecasts call for above-average (near-average) rainfall across
central Mexico (southwestern U.S.) 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:
