Intense surpluses are forecast near Fort McMurray, Alberta and Kamloops, British Columbia.
Intense water deficits that have dominated much of Australia in prior months will diminish considerably through November, but deficits of varying intensity are forecast particularly in Victoria and New South Wales, and intense deficits will increase in Tasmania covering much of the western half of the state. Deficits in New Caledonia will downgrade slightly but remain intense, and intense deficits are also expected north of Auckland, New Zealand.
Regions forecast to have significant water deficits for the 12-month period from June 2018 through May 2019 include: the US Pacific Northwest, southern Mexico, Brazil, Chile, Central and Northern Europe, northern Africa, the Middle East, Afghanistan, and southern India.

The September Outlook indicates that intense heat anomalies which have dominated Central Europe for the past month are expected to moderate overall. Exceptionally warmer than normal temperatures will prevail in Madagascar. Much drier than normal conditions are forecast in India along its southern Arabian Sea coast and also in Ethiopia's central Highlands.
For the next several months, water deficits will diminish overall but intense deficits are forecast for southern California, the Willamette Valley in Oregon, along the Arkansas River, and western Colorado.

Deficits are also forecast for northern Central America, with surpluses in the southern nations. Deficits will spread and intensify somewhat in Haiti and the Dominican Republic, and downgrade to mild in western Cuba. Jamaica will transition to extreme deficit.
