Mexico, Central America, & the Caribbean: Water deficits in Baja California & Nayarit

Mexico, Central America, & the Caribbean: Water deficits in Baja California & Nayarit

Though water deficits are forecast for Mexico over the next six months, they are expected to be primarily moderate, a significant improvement over the prior three months. Through July deficits are forecast in northwestern Mexico; scattered down the Pacific coast and central Mexico; in Yucatan, Tabasco, and Chiapas; and southern Guatemala. After July deficits will continue to emerge in Baja California, Mexico’s southern states, and northern Central America. Some modest surpluses are forecast to emerge in the north along the border of Sonora and Chihuahua. 

East Asia: Exceptional water deficits forecast for western Inner Mongolia

East Asia: Exceptional water deficits forecast for western Inner Mongolia

A return to near-normal water conditions is forecast for Southeast China from May through July, a change from surpluses observed in prior months. Deficits of varying severity are forecast for Mongolia; western Inner Mongolia, Guangdong, and Yunnan, China; and northern Japan. Surpluses are forecast in Qinghai and in a wide north/south swatch of central Tibet. The forecast for August through October shows a significant retreat of water anomalies in China’s eastern half, with some moderate deficits in Guizhou, Sichuan, and coastal Guangdong.

Middle East: Widespread water deficits ahead Saudi Arabia, Qatar, UAE

Middle East: Widespread water deficits ahead Saudi Arabia, Qatar, UAE

Severe to exceptional water deficits are forecast throughout Saudi Arabia from May through July, increasing in extent from the prior three months, and in southern Iraq and west of the Euphrates. Deficits nearly as intense will emerge in United Arab Emirates, Qatar, and Lebanon. Deficits of varying severity are forecast for Turkey, Lebanon, West Bank, Israel, Jordan, Yemen, Oman, and eastern Iran. Surpluses may persist in northeastern Iraq into northwestern Iran. The forecast for August through October shows a distribution pattern similar to May through July.

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. 

Central Asia & Russia: Water surpluses forecast for Volga River Basin, & from Ob to Tom River

Central Asia & Russia: Water surpluses forecast for Volga River Basin, & from Ob to Tom River

Widespread exceptional water deficits in northern Russia observed in the prior three months are forecast to retreat May through July. However, drier than normal conditions will persist from the Yamal Peninsula to the Sea of Okhotsk. Exceptional surpluses are forecast in the Volga River Basin, the Irtysh, and between the Ob and the Tom Rivers. Surpluses will continue to emerge in many parts of Kazakhstan and are also forecast for eastern Uzbekistan, Kyrgyzstan, and Tajikistan. Moderate deficits are forecast for Turkmenistan and central Uzbekistan. Beyond July the forecast shows a similar geographic distribution of anomalies but with some changes in conditions.

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.
