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


*African Monsoons (AFMS.ppt):*

Above-average rainfall was observed over local areas in West and Central

Another week of moderate to heavy rainfall sustained moisture surpluses
across South Sudan and western Ethiopia, whereas below rainfall was
observed over Equatorial Guinea, Gabon, central DRC and Uganda.

Week-1 outlooks call for an increased chance for above-average rainfall
over Liberia, Cote d’Ivoire, Ghana, southern Togo, Benin, southern Benin,
portions of Nigeria, Cameroon, CAR and western South Sudan. In contrast,
there is an increased chance for below-average rainfall over northern
Guinea, parts of southern Mali, and central DRC.

*Asian-Australian Monsoons (AAMS.ppt):*

For the past 90 days rainfall amounts are showing deficits to various
extents over large parts of Australia and southeast Asian countries such as
Thailand, Laos, Vietnam, and Cambodia, the Philippines and eastern Papua
New Guinea.  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 Thailand, Laos, Cambodia,
Vietnam, the Philippines islands, central eastern Australia. However,
northeast India, Burma, and parts of  southeastern China and Indonesia had
received more rainfall.

In this past week, tropical storm Roanu in the northern Indian Ocean and
Bay of Bengal region, grazed the southern and east coast of India and
finally moving on towards northeast India and Burma, gave plenty of rain to
these regions. However, the record pre-monsoon heat over interior India has
taken many lives, according to press reports. Temperatures in some parts of
interior India have soared to excess of 125 degrees F. The India Met Dept
(IMD) has announced the Indian summer southwest monsoon onset over Kerala
on the 7th of June, about a week later than normal. In the next couple of
weeks the NCEP GFS model is predicting generally normal-below normal
rainfall for the whole region, except for above normal rainfall over
southeast Asian countries in the first week

*South American Monsoons (SAMS.ppt):*

Long-term rainfall deficits continue over the Amazon Basin and central
Brazil. The rainy season has ended over central Brazil.

During the last 7 days (16-22 May 2016), below-average precipitation was
observed over most of the Amazon Basin in Brazil, western Colombia and
southern Chile.  Above-average precipitation was observed over portions of
southern Brazil.

For  23-29 May 2016, below-average precipitation is predicted for the
Amazon Basin, southern Brazil, Uruguay and southern Chile. Above-average
precipitation is predicted for western Venezuela and most of Colombia and
