Severe to exceptional surplus will affect several regions of southern Mexico and Central America. Severe to exceptional deficits will continue in northwestern and central areas of Mexico.
Widespread severe to exceptional surpluses in western and central Europe will mostly resolve, becoming near-normal conditions. Eastern European countries are expected to observe widespread deficits of varying intensity.
Moderate to severe surpluses will remain in northern areas of Australia.
Exceptional deficits will continue in Amazonas and the Bolivarian Nations, but will diminish in size.
Widespread water surpluses observed in prior months will shrink through November. However, a broad column of surplus is forecast from southern North Dakota reaching into north-central Texas with intense anomalies in South Dakota. Other areas of surplus include eastern Nevada into western Utah, Wyoming, and California from San Francisco through the southwest. A pocket of exceptional deficit is expected in the central Everglades.
Water surpluses are forecast to be the dominant anomaly in the U.S. through April 2020. Through October, significant surpluses are forecast from South Dakota into Texas and will be particularly widespread and intense in South Dakota. Surpluses are also expected in parts of the Rockies, pockets in the Southwest, nearly all of California, Michigan, pockets in the Ohio River Valley, and near Tampa Bay, Florida. Areas of deficit include the Pacific Northwest, northern Minnesota, and the Carolinas.
The forecast through July indicates widespread water surpluses of varying intensity a vast area on either side of the Mississippi River. Exceptional anomalies are forecast around Sioux Falls, and along the Mississippi River on either side of Memphis and from Louisiana to the Gulf. Surpluses will increase in the Rockies and shrink slightly and moderate in California. In the Pacific Northwest, deficits will shrink in Washington; Oregon will transition from deficit to moderate surplus.
The forecast through June indicates that surpluses East of the Mississippi will nearly disappear. Moderate deficits are forecast for the South Atlantic States and parts of the Deep South. Surpluses are forecast in the center of the country radiating from Nebraska and Iowa and will emerge in the Rockies with intense anomalies in many places, particularly Colorado. Primarily moderate surpluses are forecast for nearly all of California as well as northern Arizona and much of Oregon.
Most notable in the forecast through May is the absence of widespread, intense water surpluses observed in the East in prior months and the emergence of surpluses in the West. Surpluses will shrink and downgrade in the center of the country but remain widespread in a broad path from southern Minnesota to the Gulf of Mexico and will be intense in Kansas. Moderate surpluses will cover much of California, and many Rocky Mountain States will transition from deficit to surplus.
