Southeast Asia & the Pacific: Retreat of water surpluses forecast

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.

Southeast Asia & the Pacific: Water deficits in Cambodia and Mekong Delta

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.

Southeast Asia & the Pacific: Water deficits to emerge in northern Vietnam; surpluses persist in Phetchaburi, Thailand

Southeast Asia & the Pacific: Water deficits to emerge in northern Vietnam; surpluses persist in Phetchaburi, Thailand

Much of the region has experienced exceptional water surplus conditions in the most recent observations. 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.

Southeast Asia & the Pacific: Water deficits forecast for Papua New Guinea, Myanmar, & Thailand

Southeast Asia & the Pacific: Water deficits forecast for Papua New Guinea, Myanmar, & Thailand

From May through July moderate to severe water deficits are forecast to emerge in eastern Myanmar and western Thailand. Exceptional deficits in Papua New Guinea will downgrade but severe to extreme deficits will persist and emerge farther west into Papua, Indonesia. Moderate deficits are forecast to emerge in the western two-thirds of Indonesian Borneo. Surpluses reaching exceptional severity will persist in Sumbawa and Flores Islands, Indonesia, and moderate surpluses are forecast for northeastern Borneo and southern Philippines. After July deficits in the region will downgrade and surpluses will nearly disappear. 

Southeast Asia & the Pacific: Deficits to emerge on Java; surpluses Vietnam, Malay Peninsula

Southeast Asia & the Pacific: Deficits to emerge on Java; surpluses Vietnam, Malay Peninsula

From April through June water deficits are forecast to emerge on Java, southern Sumatra, and southern Borneo, but will recede in Cambodia except for a pocket of exceptional deficits northeast of Tonlé Sap. Surpluses are forecast for central Vietnam, the Malay Peninsula, northern Sumatra, northeast Borneo, and Mindanao. After June, deficits are forecast for most of the region, with severe to exceptional deficits in Malaysia, Indonesia, Papua New Guinea, and eastern Mindanao.

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
