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.
The widespread exceptional water deficits that have dominated Afghanistan in recent months will moderate through December though deficits will remain more intense northeast of Kabul. Moderate deficits are forecast for southern Pakistan. In India, deficits will also moderate but will be intense along the Tungabhadra River in the southwest, and in Madhya Pradesh, Bihar, and Arunachal Pradesh. Areas of surplus include northernmost India, Uttar Pradesh, Nepal, Bangladesh, and Sri Lanka.
The forecast through November indicates that water deficits will persist in Afghanistan, but exceptional deficits will retreat to the southwest. Deficits in southwestern Pakistan will downgrade but remain intense. In India, significant deficits are forecast in the southern third of the country and may be exceptional in pockets of Karnataka and Kerala. Surpluses will downgrade but remain intense in Jammu and Kashmir, Uttar Pradesh, Manipur, Tripura, and Mizoram, Nepal, and Bangladesh.
Through October, exceptional water deficits will dominate Afghanistan’s west and northwest. In India, moderate deficits will cover much of the southern two-thirds of the country with more intense deficits in western Telangana, Karnataka, southeastern Andhra Pradesh, Tamil Nadu, and central Chhattisgarh. Surpluses will downgrade but remain intense in Bangladesh, and will shrink and moderate in Nepal, though remaining exceptional along the Gandaki River.
A relatively consistent pattern of water anomalies is forecast from September through May characterized by exceptional deficits in central India and surpluses in Bangladesh, Nepal, and far eastern India. In the near-term, intense deficits are forecast in Madhya Pradesh and Chhattisgarh trailing west, east, and south. Deficits are also forecast in Karnataka, Goa, coastal Maharashtra, and southwestern Afghanistan and Pakistan. Exceptional surpluses will continue to emerge in Bangladesh, Tripura, and Mizoram. Some severe surpluses are forecast to emerge near Bengaluru, Karnataka. After November, severe to extreme deficits are forecast to emerge in Arunachal Pradesh.
