The forecast through November indicates that water deficits in India will nearly disappear, as areas of deficit normalize or transition to surplus. Surpluses will persist in a vast stretch from Gujarat through Rajasthan, increasing in Madhya Pradesh. Surpluses are also forecast from Mumbai into Karnataka, and for central Uttar Pradesh. Southern India and Sri Lanka will transition from deficit to surplus. Widespread surpluses will persist in central Afghanistan.

Through February, exceptional water deficits are forecast in India from Gujarat through Maharashtra and Karnataka, and deficits of varying severity in many regions south of the Gangetic Plain and to the west in Rajasthan. In Pakistan, isolated intense deficits are possible in Karachi. Moderate deficits are forecast in northern Afghanistan, but conditions may be intense northeast of Kabul and along the Harirud River in the west. In Bangladesh, exceptional surpluses are forecast in Chittagong.
A relatively consistent pattern of water anomalies is forecast from September through May characterized by exceptional deficits in central India and surpluses in Bangladesh, Nepal, and far eastern India. In the near-term, intense deficits are forecast in Madhya Pradesh and Chhattisgarh trailing west, east, and south. Deficits are also forecast in Karnataka, Goa, coastal Maharashtra, and southwestern Afghanistan and Pakistan. Exceptional surpluses will continue to emerge in Bangladesh, Tripura, and Mizoram. Some severe surpluses are forecast to emerge near Bengaluru, Karnataka. After November, severe to extreme deficits are forecast to emerge in Arunachal Pradesh.
Regions forecast to have significant water deficits for the 12-month period from June 2017 through May 2018 include: Montana (US), Nayarit (Mexico), Amapá (Brazil), Italy, the Arabian Peninsula, Madhya Pradesh and Chhattisgarh (India), Cambodia, Mongolia, and Tasmania (Australia). Water surpluses are forecast for: US Gulf Coast, La Pampa (Argentina), Tanzania, Bangladesh, Tripura and Mizoram (India), western Myanmar, Laos, Jiangxi and Guangxi (China), and Transvolga (Russia).

Though there are several regions with a July forecast of significant precipitation anomalies - India's Western Ghats will be much drier than normal and northern Argentina will be much wetter - the temperature forecast has more severe and widespread anomalies. The African Sahel, Saudi Arabia, and Mongolia are among the numerous regions forecast to see much warmer than normal temperatures.
South Asia: Exceptional deficits forecast across much of India through February; notable surpluses in southeastern India
The forecast through August 2016 indicates water deficits in southern Afghanistan, Pakistan, and most of India, with some areas experiencing both deficits and surpluses. Notable surpluses are forecast in southeastern India. Surpluses are also forecast for Sri Lanka, northeastern Afghanistan, Nepal, and Bangladesh.
Regions likely to encounter significant water deficits in the coming months include: the Mississippi Valley, US; southern Mexico; northern Brazil; North Africa, coastal West Africa, southern Africa; Mediterranean Europe; the Arabian Peninsula; and Southeast Asia. Significant water surpluses are forecast for: the Southern Plains and Florida, US; central Argentina; Tanzania and Kenya; southeast India; and southeast China. This watch list is based on ISciences' Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 8 December 2015.
While water surpluses may persist in northeastern Afghanistan, Nepal, Bangladesh, and Sri Lanka, the remainder of South Asia is expected to experience water deficits. Of particular interest are the widespread and exceptional water deficits forecast for much of India November 2015 through January 2016.
