[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 exceeded 100mm across eastern Sudan and western
Ethiopia.



Week-1 outlooks call for an increased chance for above-average rainfall
across many places in the Sahel and northern Gulf of Guinea countries, and
western Ethiopia.



There is an increased chance for below-average rainfall over northeastern
DRC, and parts of southern CAR and southern South Sudan.





*Asian-Australian Monsoons:*



For the past 90 days, below normal rainfall deficits remain over
southeastern China, across much of central India, over almost all of
Australia, New Guinea, and parts of Malaysia. Elsewhere, the rainfall
amounts received were at normal to slightly above normal levels. For the
past 30 days, rainfall deficits are noted across central India, eastern
China, Papua New Guinea and southern Philippines. Elsewhere rainfall
received was at slightly elevated levels.



In this past week, rainfall amounts were deficient across most of India and
sporadically across east Asia. Elsewhere rainfall was quite spotty and
spatially irregular. According to the India Met. Dept, since the first of
June till today, All India Rainfall has been 9% deficient.  In the upcoming
two weeks, the NCEP GFS model forecast is predicting below normal rainfall
over south central India, and south central and eastern China. Above normal
rainfall is forecast over north central and northern India, and over
southeast Asian countries Thailand, Laos, Cambodia, Vietnam and southern
Burma.





*North American Monsoons:*



Below-average rainfall has been observed over northwestern, central and
southern Mexico during the past week.



Rainfall accumulations over the past 30 days were above-average for
portions of central Mexico and below-average for much of southern Mexico.



NCEP/GFS Forecasts call for above-average precipitation for southwestern U.
S. and below-average precipitation for central and southern Mexico during
09-15 July, 2018.
