The forecast through June indicates that widespread water surpluses in India will shrink leaving nearly normal conditions in the east. Surpluses will persist, however, in many regions including central India, the Far North, and the Gangetic Plain; and, Pakistan and Afghanistan. Deficits will emerge in India’s Far Northeast.
