Anomalies are expected to be exceptional, 40+ years return period, around the Baltic Sea and well into northern European Russia. Eastern Europe and the Balkans will be drier than normal.
The forecast through December indicates that prior exceptional water deficits in Turkmenistan, Uzbekistan, western Kazakhstan, and the North Caucasus region will downgrade considerably, leaving primarily mild conditions. In Russia, surpluses will increase between the Ob and Yenisei Rivers and will be extreme to exceptional. Moderate deficits are forecast in the southern Ural Mountains, with surpluses to the west. Surpluses will re-emerge in the Upper Don River watershed.
The extent of exceptional water deficit in the region will diminish considerably through December, though deficits will cover most of Brazil and will be intense across the north, in Mato Grosso, São Paulo, and Paraná. Intense deficits are also forecast in Bolivia from east of La Paz through Cochabamba to the south, and from southern Peru through the Atacama Desert in northern Chile past Santiago. Surpluses will persist in Uruguay, and in Entre Rios and Buenos Aires Provinces in Argentina, and will emerge in Rio Grande do Sul, Brazil.
Mexico, Central America, & the Caribbean: Water surpluses forecast for Coahuila, Sinaloa, Chihuahua, & Zacatecas, Mexico
The forecast through December indicates pockets of intense water deficit in Mexican states along the southern Gulf of Mexico and across to the Pacific. Moderate deficits are forecast for Yucatan and Mexico’s southern Pacific coast. Surpluses will persist in Coahuila, and will increase in northern Sinaloa, western Chihuahua, and from Zacatecas through Mexico City. Surpluses are expected in eastern Guatemala and eastern Costa Rica. Deficits in Cuba will moderate.
Widespread water surpluses will emerge south of the Yangtze River and in the Pearl River watershed over the next few months and may persist through March. Surpluses are also forecast for Sichuan, Qinghai, and Tibet and may persist even longer. Deficits will increase and intensify from western Inner Mongolia through Xinjiang, and moderate to severe deficits will emerge from the North China Plain to the Yangtze River. Extreme surpluses are forecast for southern Japan, and deficits for southern North Korea.
The widespread exceptional water deficits that have dominated Afghanistan in recent months will moderate through December though deficits will remain more intense northeast of Kabul. Moderate deficits are forecast for southern Pakistan. In India, deficits will also moderate but will be intense along the Tungabhadra River in the southwest, and in Madhya Pradesh, Bihar, and Arunachal Pradesh. Areas of surplus include northernmost India, Uttar Pradesh, Nepal, Bangladesh, and Sri Lanka.
Moderate deficits will dominate much of Europe from through December, downgrading from prior exceptional deficits in many areas. Severe to extreme deficits are, however, forecast for southern Sweden, central Finland, southern France, Switzerland, and southern Germany. Norway is expected to transition from exceptional deficit to moderate surplus or normal conditions. Moderate surpluses are also forecast in Scotland and extreme surpluses in west-central Sweden. Surpluses of varying intensity are forecast for European Russia and eastern Ukraine.
Water deficits are expected to shrink and downgrade significantly through December but intense deficits will persist in southern Iraq. Severe deficits are forecast for Georgia, Kuwait, most of Saudi Arabia, and into western United Arab Emirates. Deficits of varying severity are expected in Yemen, moderate to severe deficits in central and southern Iran, and mild deficits in the Levant.
The forecast through December indicates that water surpluses will shrink but intense surpluses are forecast for western Myanmar, northern Laos, and northern Vietnam. Exceptional deficits will persist in western Cambodia. Deficits will increase in Thailand and will emerge in eastern and southern Sumatra and on smaller islands in the region. Philippines will transition from surplus to deficit. Deficits in Papua New Guinea, though downgrading, will remain severe.
The forecast through December indicates that intense deficits will shrink considerably across northern Africa but emerge across the southern Sahara and into the Sahel. Intense deficits are forecast for the Nile River and western Ethiopia. Mild deficits are forecast for much of Africa’s southern half. Areas of surplus include southern Mali, Sierra Leone, Liberia, Burkina Faso, Ghana, coastal and northeastern Nigeria, south-central Chad, Republic of the Congo, Tanzania, and southern Kenya.
