The forecast through August 2019 indicates that water deficits will remain intense in Northern Europe, especially in Finland, Estonia, and Latvia. Other areas of intense deficit include Luxembourg, northern Germany, central France and the Loire River, and along the Drava River through Austria. Areas of surplus include Scotland, central Italy and around the Adriatic Sea, Serbia, and northern Romania.
The forecast through April indicates persistent, intense water deficits in Finland, southern Sweden, Estonia and Latvia. Other areas with pockets of fairly intense deficit include northern Germany, Luxembourg, Belgium, Netherlands, Denmark, and eastern Slovenia and Croatia. Moderate to severe deficits are expected in Belarus and across the border into European Russia past the Volga River. Regions with surpluses include Switzerland, Austria, the Balkans, Romania, eastern Ukraine, and Crimea.
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.
In the near-term through January, widespread water deficits are forecast though exceptional deficits will shrink. Areas of intense deficit include: the Balkans, Ireland, Germany, France, Luxembourg, Belgium, Netherlands, Denmark, southern Norway, Estonia, and Latvia. Areas of surplus include Norway, northern European Russia, Scotland, and Sicily.
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.
Intense water deficits will give way to milder conditions after November along with some pockets of moderate surplus. Until then, severe to exceptional deficits are forecast for Germany, particularly in the south and along the Rhine River, as well as in Switzerland, Finland, southeastern Norway, and southern Ireland. Moderate to severe deficits are expected in many other areas including the Baltics, parts of Eastern Europe, Scotland and England, and much of France. Areas of surplus include Hungary and parts of Serbia, Romania, and Bulgaria. Surpluses will be intense in southern Hungary.
The forecast through October indicates that exceptional water deficits will diminish considerably but widespread deficits will continue to affect many parts of Central, Eastern, and Northern Europe and will be especially intense in Finland, Estonia, and southern Germany. Moderate deficits will increase in France. Surpluses are forecast for Hungary, Serbia, Kosovo, Romania, Bulgaria, and Moldova. On the Iberian Peninsula, surpluses will diminish overall, but persist in many parts of Spain and may be exceptional in the south.
The August Outlook indicates much warmer than normal temperatures in much of Europe reaching exceptional intensity in parts of Central Europe and southern Scandinavia. Precipitation is expected to be above average in Greece, Italy, and across the Mediterranean into Algeria.
