Southeast Asia & the Pacific: Retreat of water surpluses forecast

Though a significant retreat of exceptional water surplus in the region is forecast through October, exceptional surpluses remain in the forecast for: western Myanmar; eastern Thailand into southern Laos; and, southeastern Sulawesi and Sumbawa and Flores Islands in Indonesia. Exceptional deficits are forecast for a large block of western Cambodia, and deficits of varying severity are forecast for the Mekong Delta, southern Thailand, Singapore, Malaysian Borneo, southern Sumatra, and pockets in central Papua New Guinea. After October, near-normal conditions are expected in many parts of the region and deficits in western Cambodia will moderate.

The July through September forecast shows the near absence of widespread surpluses observed in prior months. However, exceptional surpluses are forecast for western Myanmar; northern Prachuap Khiri Khan Province, Thailand; the extreme southeastern region of Sulawesi; and Flores Island in Indonesia. Severe to exceptional deficits are indicated in much of Cambodia, in Vietnam’s Mekong Delta, and in central Papua New Guinea. In the October-December timeframe moderate deficits are indicated in many parts of the region, and thereafter deficits in Southeast Asia may intensity.

These moderate in the near-term forecast and subside completely September through February 2018. Recently observed exceptional deficits in Cambodia and Papua New Guinea subside during the June through August period. In the December through February 2018 forecast period deficits may emerge over mainland Malaysia and coastal Myanmar.
