Severe to exceptional surplus will affect several regions of southern Mexico and Central America. Severe to exceptional deficits will continue in northwestern and central areas of Mexico.
Widespread severe to exceptional surpluses in western and central Europe will mostly resolve, becoming near-normal conditions. Eastern European countries are expected to observe widespread deficits of varying intensity.
Moderate to severe surpluses will remain in northern areas of Australia.
Exceptional deficits will continue in Amazonas and the Bolivarian Nations, but will diminish in size.
Regions forecast to have significant water deficits for the 12-month period of December 2020 through November 2021 include: Brazil, Estonia, Latvia, and the U.S. Southwest.

The forecast through March 2020 indicates that water surpluses of varying intensity will continue to dominate the breadth of India with intense anomalies in central Rajasthan, Madhya Pradesh, western Maharashtra, south-central Karnataka, central Chhattisgarh, and the Far East. Surpluses are also forecast for Bangladesh, Nepal, Bhutan, Sri Lanka, rivers in Pakistan, and central Afghanistan.
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.
The forecast through October indicates normal water conditions for many parts of India as deficits nearly disappear. Surpluses are forecast in the far north and northeast, the western Gangetic Plain, Rajasthan, along Gujarat’s northern border, and southeastern Maharashtra. Widespread surpluses will persist across central Afghanistan, in northern Pakistan and along rivers, in central Nepal, and throughout Bangladesh.
