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


*African Monsoons:*

Weekly total rainfall exceeded 100m over local areas in Senegal and
southwestern Mali, western Guinea and northern Sierra Leone, local areas in
Cote  d’Ivoire, northern Togo, portions of eastern Nigeria, northern
Cameroon, and local areas in western CAR, whereas suppressed rainfall
prevailed over Uganda, and eastern South Sudan.

Week-1 outlooks call for an increased chance for above-average rainfall
over much of Senegal, Gambia, Guinea-Bissau, Guinea-Conakry, Sierra Leone,
Liberia, parts of southern Mali, Cote d’Ivoire, portions of Ghana, and
western Ethiopia. In contrast, there is an increased chance for
below-average rainfall over parts of eastern DRC, Uganda, portions of
western Kenya, and eastern 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, parts of Japan and
Papua New Guinea, but above normal elsewhere particularly the Indonesian
archipelago and the Philippines. For the past 30 days the rainfall
situation is overall a dry pattern over southern peninsular India and
central and eastern China, the Koreas, southwest Japan, the Philippines and
New Guinea. Elsewhere, rainfall was at generally near normal or above
normal levels.

In this past week, monsoon rainfall was generally deficient across much of
the region. Typhoon Lionrock brought high seas and havoc to Japan, but
bringing the much needed rainfall to the dry conditions there.  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
with  about
-3 % level across the country. In the next couple of weeks the NCEP GFS is
predicting generally below normal rainfall over much of the region,
combined with the expected gradual withdrawal phase of the southwest summer
Indian monsoon from the north and western parts of India. Less rainfall is
also predicted over central eastern China, while above normal rainfall is
forecast near coastal southern China

*North American Monsoons:*

Near-average rainfall has been observed over southwestern U.S. during the
past week.

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

NCEP/GFS Forecasts call for near-average precipitation for Arizona/New
Mexico during 06 - 19 September, 2016.

*South American Monsoons:*

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