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 Central and East Africa had above-average rainfall. In
contrast, suppressed rainfall prevailed over many places in the Southern
Africa countries.

Week-1 outlooks call for an increased chance for above-average rainfall
over eastern Liberia, portions of Cote d'Ivoire and southwestern Ghana,
portions of Ethiopia, portions of eastern Zambia and Zimbabwe, Malawi, and
northern Mozambique. In contrast, there is an increased chance for
below-average rainfall over portions of northeastern DRC, Rwanda, Burundi,
Uganda, western Kenya, and portions of Tanzania.

*Asian-Australian Monsoons:*

For the past 90 days, slight to heavy rainfall deficits remain over parts
of  central and eastern Australia, as well as over Papua New Guinea.
However, rainfall situation is generally better in western Australia,
particularly in the northern region. Elsewhere, the rainfall situation is
at or near normal levels. In the longer 180 days term, severe deficits
remain over southern India and over central and eastern Australia. For the
past 30 days  rainfall deficits are found over western Australia and over
Japan. Elsewhere, the rainfall amounts are at near or above normal levels.

In this past week,  the rainfall was slightly above normal over
southeastern China and southeastern Australia. Elsewhere it is a mixed
pattern. In the next couple of weeks the NCEP GFS model is predicting
slightly above  normal rainfall over southeastern China and southeast Asian
countries except parts of Indonesia, and in the second week over northern

*South American Monsoons:*

Long-term rainfall deficits are present over the Amazon Basin and central

During the last 7 days (13 - 19 Mar 2017), below-average precipitation was
observed over much of central Brazil, northeastern Peru, Uruguay, northern
Argentina and southern Chile.  Above-average precipitation was observed
over portions of western Colombia, Ecuador, northern Peru, Paraguay,
northern and the extreme southern Brazil.

For 20 – 26 Mar 2017, below-average precipitation is predicted over much of
Brazil, Bolivia, Paraguay, Uruguay and southern Chile.  Above-average
precipitation is predicted for large portions of northwestern South America.
