Mexico, Central America, & the Caribbean: Water deficits forecast for Yucatan

Mexico, Central America, & the Caribbean: Water deficits forecast for Yucatan

The forecast through April indicates that water surpluses in northern Coahuila, Mexico will remain intense. Surpluses will also persist from Zacatecas through Mexico City into northern Oaxaca, broken by a pocket of exceptional deficits in southern Puebla. Other areas of deficit include the northern Yucatan Peninsula, southern Chihuahua, northern Durango, and scattered small pockets in the south. Intense deficits are forecast for western Panama and moderate deficits will emerge in eastern Jamaica.

Southeast Asia & the Pacific: Water deficits forecast for Cambodia, Thailand, & Philippines

Southeast Asia & the Pacific: Water deficits forecast for Cambodia, Thailand, & Philippines

The forecast through April indicates that exceptional water deficits in western Cambodia will shrink slightly, deficits in Thailand will downgrade, and moderate deficits will emerge in northern Myanmar. Deficits are also forecast for the Philippines, eastern Borneo, northern Sulawesi, pockets of Sumatra, and central New Guinea. Moderate to severe surpluses are forecast for much of Vietnam with exceptional conditions in the north including Hanoi, and in north-central Laos.

United States: Water surpluses to persist WI to TX, emerge in CA

United States: Water surpluses to persist WI to TX, emerge in CA

Most notable in the forecast through April is the absence of widespread, intense water surpluses observed in the East in prior months. Surpluses will, however, persist in a massive path down the center of the country from Wisconsin through Texas, and moderate surpluses will emerge in the Rocky Mountains, in California from San Francisco Bay to the southern border, and along the Missouri and Colorado Rivers. Surpluses will be exceptional in central Kansas, on the Arkansas River, and in central Texas.

Middle East: Water surpluses to persist from Turkey through western Iran

Middle East: Water surpluses to persist from Turkey through western Iran

The forecast through April indicates water deficits on the Arabian Peninsula and southern Iran, and surpluses from Turkey through western Iran. Exceptional deficits will increase in western Oman, downgrade somewhat in Yemen, and moderate to severe deficits are expected in much of Saudi Arabia. Deficits will downgrade in United Arab Emirates and moderate deficits will emerge in Qatar.

Africa: Water deficits forecast to increase across the Sahel

Africa: Water deficits forecast to increase across the Sahel

The forecast through April indicates that water deficits will downgrade in the southern half of the continent, becoming primarily moderate across the central breadth and mild in the south. Deficits in the north will increase and intensify, with moderate to extreme deficits in the Sahara and deficits reaching exceptional intensity in parts of the Sahel and into western Ethiopia. Intense deficits will linger in Cameroon, Equatorial Guinea, and Gabon. Surpluses will persist in western Tanzania.

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.
