DELAYED: Release of Global Water Monitor & Forecast Watch List January 2019 is delayed due to partial government shutdown.
The January Outlook indicates much wetter than normal conditions forecast for southern China through the Pearl River Basin encompassing the Pearl’s northern tributaries; and, oceans away in Uruguay. Temperatures in Northeast China are expected to be exceptionally warmer than usual, anomalies with a return period of 40 or more years.
Through February, widespread intense water surpluses will persist in the center of the country and in the east. Surpluses will cut a broad path from Michigan’s Upper Peninsula, passing through Iowa and reaching the eastern half of Texas. Surpluses are also forecast for the northern Ohio River Basin and in the east from southern New York through Florida’s Panhandle, and will be extreme in eastern Pennsylvania. Areas of deficit include: northern New York, northern Maine, southern Florida, northwestern Wyoming, Colorado, and western Oregon.
The forecast through February indicates a pattern of anomalies similar to the prior three months, including: exceptional water deficits in Quebec, notably in the Ottawa-Gatineau River region in the south and across the border into Ontario; intense deficits in the Middle and Upper Reaches of the Athabasca River watershed in Alberta; and intense surpluses in southeastern British Columbia. Deficits are expected to increase in southern Saskatchewan where anomalies will be severe to exceptional.
For the next three months, water surpluses will persist in northern Coahuila, Mexico, and along a diagonal from southern Durango through Mexico City, broken by a pocket of exceptional deficits in southern Puebla, and continuing into northern Oaxaca. Intense surpluses are forecast in Nicaragua. Areas of deficit include: the Rio Grande in Chihuahua, northern Yucatan, western Panama, Jamaica, Haiti, and Dominican Republic.
Exceptional water deficits will diminish considerably over the next several months but through February intense deficits are forecast in: southern Amazonas, Brazil; southeastern Venezuela; northern Chile; and southwestern Bolivia. Deficits of varying intensity are forecast in the northwest quadrant of the continent. Areas of surplus include: Amapá, Brazil, and southern Mato Grosso through western Minas Gerais; northern Bolivia; Paraguay; and the Paraná River in Argentina to Buenos Aires.
Though the extent and intensity of water deficits in Europe will diminish considerably through February, severe to exceptional anomalies are forecast in Finland, pockets of Sweden, southern European Russia, Denmark, Netherlands, Belgium, Luxembourg, western Germany, and eastern Slovenia and the Sava River Basin in Croatia and northern Bosnia-Herzegovina. Areas of surplus include Norway, northern European Russia, and the United Kingdom.
The forecast through February indicates that water deficits will downgrade considerably. However, areas with notably intense conditions include western Ethiopia; pockets of northern Somalia, Nigeria, and southwestern Cameroon; southwestern Angola into Namibia; and, Lesotho and the Orange River region of Northern Cape, South Africa. Surpluses are forecast for Tanzania, southern Congo into western DRC and northern Angola, and south-central Chad.
Water deficits are expected to shrink and downgrade through February though intense deficits are forecast for Yemen’s western and eastern thirds and severe deficits in Saudi Arabia’s large south-central region of Riyadh. Surpluses will persist in western Iran north of the Red Sea and across the border into Iraq and will remain intense. Surpluses are also forecast along Iran’s western Caspian Sea coast; north of Kirkuk, Iraq; and in eastern Turkey.
The forecast through February indicates intense water surpluses on the Ob, Vakh, Pur, and Taz Rivers in Russia. Surpluses will be widespread in the Middle Ob region and the Yenisei River watershed. Severe to extreme deficits are forecast for western Kazakhstan, reaching across the northern border into the Ural River watershed in Russia. Surpluses are expected in northern Kazakhstan, eastern Kyrgyzstan, western Tajikistan, and along the Zerafshon River in Ubekistan. Deficits are forecast for eastern Tajikistan and central Kyrgyzstan.
