The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems (SAMS.ppt, AFMS.ppt and AAMS.ppt) have been
updated on the CPC Global Monsoons website:


*African Monsoons (AFMS.ppt):*

Above-average rainfall was observed over Guinea-Conakry, Sierra Leone,
Gabon, and portions of DRC and western Ethiopia, whereas suppressed
rainfall prevailed over Uganda and parts of southern Ethiopia.

Week-1 outlooks call for an increased chance for above-average rainfall
over southern and eastern Guinea-Conakry, Sierra Leone, Liberia, western
Cote d'Ivoire, southern Cameroon, Equatorial Guinea, Gabon,
Congo-Brazzaville, and portions of western DRC. In contrast, there is an
increased chance for below-average rainfall over eastern Conte d'Ivoire,
southern Ghana, Togo, southern Benin and southern Nigeria.

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

For the past 90 days, the precipitation pattern over eastern Afghanistan,
northern Pakistan, northern Kashmir and over entire India was at near to
slightly above normal levels for this time of the year.  Rainfall was also
much above normal over southwestern Borneo island. However, rainfall was
below to much below normal elsewhere over southern Philippines,
southeastern China across Malaysia, Indonesia and across entire northern
and north central Australia. For the past 30 days, the precipitation over
southern India, northeast India, Nepal, and Bangladesh and vicinity was
normal to above normal for this time of the year.  However, rainfall was
much below normal over southeastern China, Laos, Vietnam, Cambodia, parts
of Indonesia and papa New Guinea. Overall, precipitation over Australia was
near normal for the last thirty days.

In this past week, the precipitation was above normal over Tamilnadu and
Kerala states of India, northeast India, Bangladesh and eastern China.
Elsewhere, the rainfall was at or below normal levels. In the next couple
of weeks, the NCEP GFS model is predicting above normal precipitation over
much of Burma, and adjoining regions of China and coastal southeastern
China. Elsewhere, below normal rainfall is forecast by the models.
Interestingly, through the month of May, the model is predicting below
normal along southern India, the traditional onset region of the summer SW

*South American Monsoons (SAMS.ppt):*

Large long-term rainfall deficits remain over the southern Amazon Basin and
portions of central Brazil.

During the last 7 days (11-17 May 2015), below-average precipitation was
observed over northern and northeastern South America, southern Brazil and
Uruguay.  Above-average precipitation was observed over portions of Peru,
Bolivia, and southern Chile.

For 18-25 May 2015, above-average rainfall is predicted for portions of
Colombia, Venezuela and extreme northern Brazil. Drier-than-average
conditions are predicted for most of Brazil south of the equator and most
of Peru.
