Mexico, Central America, & the Caribbean: Water deficits forecast for Baja & Nayarit

Mexico, Central America, & the Caribbean: Water deficits forecast for Baja & Nayarit

Intense water deficits across northwestern Mexico are expected to moderate from January through March, but moderate to severe deficits will spread in the north-central states. Intense deficits will emerge in Nayarit, Jalisco, Colima, and Michoacán. Deficits in western Cuba will moderate. Significant surpluses are expected to persist in Honduras, Nicaragua, northern Costa Rica, and Jamaica. After March, deficits are forecast in northern Mexico, moderate surpluses along the southwestern coast, and surpluses in Central America will diminish. 

Canada: Water deficit persists on the QC/ON border, surplus near Kelowna, BC

Canada: Water deficit persists on the QC/ON border, surplus near Kelowna, BC

The near-term forecast indicates a pattern of water anomalies much like the prior three months. Widespread surpluses will continue in northeastern Quebec, central Ontario, west of Lake Winnipeg in Manitoba, near Churchill Lake in Saskatchewan and into Alberta, the central border of Alberta and British Columbia, and southeastern BC. Deficit areas include: central Quebec and the Ontario/Quebec border; northwestern Ontario into central Manitoba; and southern Manitoba and southeastern Saskatchewan. After March, surpluses in Quebec and Ontario will transition to deficit. 

Middle East: Exceptional water deficits will retreat but widespread deficits will persist

Middle East: Exceptional water deficits will retreat but widespread deficits will persist

Widespread exceptional deficits are expected to moderate considerably through March, but intense deficits will continue to emerge in southeastern Turkey, Syria, Jordan, northern Saudi Arabia, and Iraq. Moderate to severe deficits are forecast throughout Iran. Deficits in Qatar, UAE, and Yemen will downgrade to primarily moderate. After March, deficits on the Arabian Peninsula are expected to resume prior intensity and deficits will emerge throughout Turkey and in nearby Georgia, Armenia, and Azerbaijan, completing a picture of deficits blanketing the entire Middle East.

Australia & New Zealand: Water deficits diminish but persist in Tasmania and South Australia

Australia & New Zealand: Water deficits diminish but persist in Tasmania and South Australia

Exceptional deficits observed in recent months are forecast to nearly disappear, though intense deficits will persist in western Tasmania and the southwestern tip of Western Australia. The near-term forecast includes moderate deficits in South Australia, becoming more intense past the Eyre Peninsula and along Victoria’s coast. Moderate deficits are expected in the eastern Murray-Darling Basin which may be more severe in Riverina, and moderate deficits are forecast for New Zealand. After March, deficits will be mild overall but more severe in Busselton, Tasmania, and New Zealand.

East Asia: Intense water deficits forecast for Shandong & Mongolia

East Asia: Intense water deficits forecast for Shandong & Mongolia

The near-term forecast indicates a vast stretch of exceptional water deficit from Xinjiang through southern Mongolia and eastern Inner Mongolia, and in Shandong, China.  Severe to extreme deficits will continue to emerge in South Korea, and the extent of deficits in Fujian and Guangdong will increase somewhat. Exceptional surpluses will continue to emerge in the Han River (Hanjiang) watersheds and the eastern stretch of the Ordos Loop of the Yellow (Huang) River. After March exceptional deficits and surpluses will retreat but some areas of intense anomalies will persist.

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.
