Middle East: Intense deficits to persist on the Arabian Peninsula

The near-term forecast through November indicates a significant retreat of exceptional deficits on the Arabian Peninsula though deficits will continue to emerge, reaching south into much of Yemen and southern Oman. Deficits in the Levant will downgrade to moderate. Exceptional deficits in Iraq west of the Euphrates are expected to become slightly less intense except in the south. Deficits will emerge throughout much of the eastern two-thirds of Iran. After November exceptional deficits are forecast to nearly disappear though widespread deficits of lesser intensity will continue to emerge.

Southeast Asia & the Pacific: Gradual transition from water surplus to deficit

The forecast indicates a transition away from widespread water surpluses and towards the gradual emergence of deficits. Exceptional deficits in western Cambodia are expected to persist through February or longer, but should diminish in extent after November. From September through November moderate deficits will begin to emerge in Thailand, the Malay Peninsula, southern Sumatra, and Java, and thereafter in Borneo and Sulawesi.

East Asia: Water surpluses in South China to diminish; deficits ahead for Hokkaido

Recent exceptional deficits in Mongolia, the Korean Peninsula, and Liaoning are expected to moderate in the near term – September through November. Widespread surpluses are expected to persist in southern China from Poyang Lake in Jiangxi southwest through Hunan into Guangxi and Yunnan, and the western Pearl River Delta, though the extent of exceptional surpluses will diminish considerably. The coastal southeast will transition from surplus to moderate deficit, a trend which is forecast to continue through May. After November, surpluses in Jiangxi through Yunnan will continue to diminish.
