[Wei Shi - NOAA Federal]

The weekly PowerPoint presentations summarizing the recent variability of
the global monsoon systems have been updated on the CPC Global Monsoons
website:
http://www.cpc.ncep.noaa.gov/products/Global_Monsoons/Global-Monsoon.shtml

*HIGHLIGHTS:*



*African Monsoons:*



Weekly rainfall surpluses, associated with tropical cyclone Kenneth,
exceeded 200mm over parts of northeastern Mozambique.



Below-average rainfall prevailed over portions of Central Africa.



Week-1 outlooks call for an increased chance for above-average rainfall
over Central African Republic, DRC, southeastern Tanzania, and parts of
northern Mozambique. In contrast, there is an increased chance for
below-average rainfall across southern Ethiopia, southern Somalia, Kenya,
and portions of Uganda and northern Tanzania.





*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits  dominated deep
southern coastal peninsular India, Korea, Japan, Thailand, Malaysia, the
Philippines, parts of New Guinea island of Indonesia and Papua New Guinea,
and much of Australia, particularly north western regions. Elsewhere, the
rainfall amounts received were at normal to slightly above normal levels,
particularly in southeastern China, Kashmir India, Nepal, parts of the
Middle East, and Indonesia. For the past 30 days, slightly above normal
rainfall across the Middle East,. Elsewhere the rainfall amounts received
were mixed. Near normal rainfall fell over Australia, except the south east.



In this past week, overall, near normal rainfall fell across the region and
above normal rainfall over the Indonesian island of Borneo and vicinity.
For the next two weeks, the NCEP GFS model forecasts near to below normal
rainfall over much of the south and south east Asian countries, except over
parts of Burma and South China Sea countries.



*South American Monsoons:*



Long-term rainfall deficits over the Amazon Basin and the Brazilian Plateau
are still present but have decreased.



During the last 7 days, below-average precipitation was observed over
portions of northern Brazil, southern Chile, northeastern Peru and
southeastern Colombia.  Above-average precipitation was observed over
portions of central and southern Brazil, northern Argentina, Paraguay and
central Bolivia.



For Days 1-7 (29 April – 05 May 2019), below-average precipitation is
predicted over much of northwestern South America, as well as the extreme
southern Brazil and portions of southern Peru and southern Bolivia.
Above-average precipitation is predicted for portions of central Brazil,
northern Argentina, southern Chile, Paraguay, Bolivia and northeastern Peru.
