United States: Widespread, intense water surpluses ahead from WI to TX

The forecast through January calls attention to significant water surpluses that will cut a wide north/south path from Michigan’s Upper Peninsula down through Texas, and will emerge in the Ohio River Valley leading into widespread surpluses in the east from Maine to South Carolina. Surpluses are expected to be exceptional in Texas, Wisconsin, and Iowa, among other areas. Moderate to extreme deficits are forecast for Florida. Deficits are also forecast for central Colorado, the Rio Grande through New Mexico, and northwestern California into Oregon.

Europe: Widespread water deficits will persist

Europe: Widespread water deficits will persist

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.

Middle East: Water deficits forecast to decrease

Middle East: Water deficits forecast to decrease

Water deficits are expected to shrink and downgrade significantly through January with conditions approaching normal in Iraq, Syria, northeastern Saudi Arabia, and Iran. Deficits will intensify in Georgia, and extreme deficits will emerge on the Kura River in Azerbaijan. Intense deficits are also forecast for southern Saudi Arabia, Yemen, and, to a lesser degree, western Turkey and along Turkey’s Black Sea coast.

Global Precipitation & Temperature Outlook November 2018

Global Precipitation & Temperature Outlook November 2018

Warmer than normal temperatures are forecast for much of Central, Eastern, and Northern Europe, extending into European Russia. 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.

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.
