Southeast Asia & the Pacific: Exceptional water surpluses forecast on Mekong River

Through October, water surpluses will persist with intensity in western Myanmar, retreat from northwestern Thailand, downgrade slightly in Laos and Vietnam, shrink considerably in the Philippines, and nearly disappear in Malaysia and Indonesia. Exceptional surpluses are forecast along the Mekong River. Deficits north of Tonle Sap in Cambodia will intensify. Deficits are also forecast for the Malay Peninsula, western Indonesian Borneo, southern Sumatra, Java, Timor-Leste, and Papua New Guinea.

The forecast indicates a transition away from widespread, intense water surplus to deficit. Deficits are forecast for peninsular Malaysia, Borneo, Sulawesi, New Guinea, Java, pockets in Sumatra, and eastern Mindanao. Deficits will diminish somewhat in northwestern Cambodia, increase in southeastern Thailand, and emerge in Vietnam east of Hanoi and in central Myanmar. Surpluses are forecast for western and southern Myanmar, northern Laos, northwestern Vietnam, eastern Cambodia into Vietnam, central Philippines, and East Nusa Tenggara.

The forecast indicates a transition away from widespread, intense water surplus to deficit. Surpluses are forecast, however, for parts of Myanmar, northern Laos, northwestern Vietnam, eastern Cambodia, central Philippines, and East Nusa Tengara. Intense deficits will emerge in southernmost Thailand, and spread in Malaysia and northern Sumatra. Deficits of varying intensity are expected to emerge throughout Indonesia and may be extreme in West Nusa Tengara and Timor-Leste. Deficits in Papua New Guinea will downgrade but remain severe.

The forecast indicates a transition away from water surplus to deficit. Moderate deficits are forecast for northern Cambodia, southern Vietnam, northern Luzon, and pockets of Sumatra and Java. More intense deficits are forecast for peninsular Thailand and Malaysia, eastern Papua New Guinea, western Timor Leste, and West Nusa Tengara. Surpluses are expected in north-central Vietnam, northern Borneo, northern Sumatra, central Philippines, North Sulawesi, East Nusa Tengara, and Pulau Sumba.

Southeast Asia & the Pacific: Exceptional deficits forecast for Peninsular Malaysia

The forecast indicates a transition away from water surplus to deficit. Deficits are forecast for mainland Southeast Asia, Peninsular Malaysia, northern Sumatra, and Luzon and Mindanao in the Philippines; deficits may be exceptional in Peninsular Malaysia. Exceptional deficits in Cambodia will shrink considerably but persist in a pocket northeast of Tonlé Sap. Severe deficits are forecast for Vietnam’s Mekong Delta region. Surpluses are forecast for central Philippines. After June, anomalies in the region will downgrade though severe deficits will continue in Peninsular Malaysia.
