Australia & New Zealand: Water surpluses forecast for Warrego River QLD & Murray River NSW

Australia & New Zealand: Water surpluses forecast for Warrego River QLD & Murray River NSW

The forecast through January shows water surpluses in the Warrego River Catchment in Queensland, between Port Pirie and Adelaide in South Australia, between the Lachlan and Murray Rivers in New South Wales, and along the southern coast of Western Australia. Mild surpluses are forecast to emerge from King Sound in Western Australia to the western shore of the Gulf of Carpentaria. Deficits are forecast south of Perth, along the Limestone Coast, southeast of Melbourne, and North Island, New Zealand.

United States: Water surpluses in Upper Midwest, Northwest, deficits in the South

United States: Water surpluses in Upper Midwest, Northwest, deficits in the South

The outlook for the United States through January indicates that water deficits will dominate the Ohio River Valley west through Arkansas and south to the Gulf, as well as the Delaware and lower Susquehanna drainages. Surpluses of varying severity are forecast for a vast block of the Northwest, Minnesota, Wisconsin, Iowa, and eastern North Carolina. From February through April the severity of both deficits and surpluses will diminish and some states in the Midwest and Northeast will transition to near-normal conditions. However, surpluses will persist in much of the Northwest and Upper Midwest.

Middle East: Water deficits to persist, though less severe

Middle East: Water deficits to persist, though less severe

The overall progression of water anomalies forecast through July indicates that widespread water deficits will persist throughout the Middle East but these deficits are expected to be less severe from November through April than in the prior three months. However, after April the forecast shows the severity level increasing, especially on the Arabian Peninsula.

Central Asia & Russia: Water surpluses forecast in the Ural River Basin

Central Asia & Russia: Water surpluses forecast in the Ural River Basin

Drier than normal conditions will continue to dominate much of northern Russia from the White Sea to the Central Siberian Plateau through July, though the extent of exceptional deficits will diminish considerably. The Ural River Basin in northwestern Kazakhstan will continue to experience exceptional surplus and surpluses are also forecast for central Kazakhstan. Overall, moderate deficits are forecast for Turkmenistan and Uzbekistan, and surpluses in eastern Kyrgyzstan.

Southeast Asia & the Pacific: Deficits persist in Cambodia, surpluses in Laos & Java

Southeast Asia & the Pacific: Deficits persist in Cambodia, surpluses in Laos & Java

Though water surpluses are forecast for many parts of the region through January, exceptional deficits will persist in Cambodia through April. Surpluses are forecast through January in Laos, southern Vietnam, Java, Flores Island, eastern Borneo, Mindanao, and western Luzon, which may be exceptional in some areas. With the exception of the Philippines, many parts of the region will transition to water deficits from February through April.

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.
