Sask.'s El Nio winter is over. What does that mean for spring?

Winter on the Prairies didn't feel like winter much of the time. That could mean prolonged drought and another challenging forest fire season.

Uncertainties loom, but above-seasonal warmth, dry conditions likely to continue

Winter 2023-24 wasone for the record books.

Canada had its warmest December, January and February often referred to as "meteorological winter" since record keeping began in 1948.

While Saskatchewan didn't rank first on record, almost all locations were within the top 10 for warmest winters, with much of the province between 2 C and 6 C warmer than normal.

A likely reason for the unusually spring-like winter weather was El Nio.

The recurring weather phenomenon makes Pacific Ocean waters near the equator,just off the coast of South America, warmer than normal. The warm waters warm the air above and that surges into North America.

"It was a strong El Nio that formed this winter, as forecast," said Terri Lang, a meteorologist with Environment and Climate Change Canada.

"We do have a correlation in Western Canada with strong El Nios in that we tend to get warmer than average winters and drier than average winters."

This El Nio appears to have been stronger in Saskatchewan than the last one during the winter of 2015-16. That eventmade parts of Saskatchewanup to 4 C warmer than normal.

This winter was one for the record books. Canada reported its warmest winter since record keeping began in 1948. That could make for another active forest fire season this spring.

John Gyakum, a professor in the Department of Atmospheric and Oceanic Sciences at McGill University, said climate change is likely amplifying El Nio's effects.

"If you look at a map of ocean temperature anomalies, it's absolutely seemingly off the charts in terms of just about everywhere," said Gyakum.

Areport from the World Meteorological Organizationshows oceansurface temperatures around the globe set a new January monthly record.

"This is worrying and can not be explained by El Nio alone," WMOsecretary-general Celeste Saulosaidin the report.

Gyakumsuspects similar conditions could happen in Canada during future El Niosif ocean temperature anomalies are similar to or higher than what they werethis winter.

"This larger background that is impacted by climate change really sets the scene for amplifying the signal of El Nio," he said.

El Nio is expected to weaken through spring and transition to a neutral phase, but the warm and dry conditions could linger even after its departure.

ECCC's three monthoutlook shows much of the country hasa goodchance of seeing above seasonal temperatures.

Farmers preparefor another drought year

Data from Agriculture and Agri-Food Canada shows much of Saskatchewan in moderate drought, with pockets of severe and extreme drought, as of the end of February.

The conditions have prompted the Agricultural Producers Association of Saskatchewanto ask the province to form a committee to addressdrought.

APASpresident Ian Boxallsaid he would like to see the committee involve government, farming groupsand researchers, among others.

"I think we can sit down and have a dialogue about what does it look like?" said Boxall. "What are the options that the province has and producers have at their fingertips that would alleviate some of these issues for producers moving forward?"

Drought forces Prairie ranchers to sell livestock

As the multi-year drought in the Prairies continues, some ranchers are being forced to sell off livestock. With little moisture in the ground and water sources drying up, feed for livestock is becoming difficult to grow.

Boxall said APAScouldform the committee themselves, even if government isn't involved.

Alberta has a similar committee, made up of"leaders with experience in agriculture, irrigation, Indigenous, industry, rural and urban issues," according to a release from the province.

Its goal is to"help the government support communities, farmers and ranchers, and businesses share, conserve and manage water during a potential drought."

Boxall said heavy snowfall earlier this month could alleviate concerns for some farmers, especially those who rely on runoff to fill dugouts for water use, but added rain this springis what's neededmost to grow crops.

Phillip Harder, a hydrologist who farms near Saskatoon, thinks the snow on his farm melts down to between 40 and 50 centimetres of water about a quarter of the moisture crops use to grow, he said.

But Harder believesmuch of this winter's melted snowwill run off, instead of soaking into the ground,because of soil conditions.

"We had early winter rain that sort of saturated the near surface, we've had mid-winter melts," said Harder."All those sequences have basically created a very thinbut very frozen surface."

A report from Saskatchewan's Water Security Agency (WSA) says much of the province is expected to see below or well below normal runoff, but parts of eastern and west-central Saskatchewan will see near normal runoff because of the heavy early March snowfall.

WSA spokesperson Patrick Boyle said dry weather in the fall caused the agency to reducethe outflow of waterfrom almost allreservoirs in the province over the winter.

"So you're retaining those inflows and then reducing the outflows so as to keep thereservoirs as high as possible," said Boyle.

In its release, the WSA noted some south-central communities could facelocalized water supply shortages this spring due to dry conditions.

But Boyle said the WSA hasworked with communities over the past few months to mitigate shortages, and no communities are immediately at risk of running out of water.

Fires burned over winter in parts of Western Canada

Piyush Jain, a research scientist with the Canadian Forest Service, told CBC over 100 fires smoulderedthrough the winter in parts of British Columbia and Alberta.There were also fires reported in the Northwest Territories.

"It's pretty common to have a few, like a handful of overwintering fires," said Jain. "But to have well over 100 is very unusual."

Jain said much of the forest in northern Saskatchewanis unmanaged, but there could have been fires smoulderingthere too.

An unusually dry winter had led to more than 100 wildfires still burning underground across Canada. That's particularly concerning in Fort Nelson, in B.C.'s far northeast, where smoke is still visible near the community

As of Mar. 23, four fires have already been reported in Saskatchewan in 2024. The five-year average for this time of year is zero.

"I think everyone's a little bit on edge waiting to see what that'll mean in the spring when the usual fire-conducive weather conditions turn up," said Jain.

Jain said it's hard to predict what this fire season will be like, but there is concern given much of the Prairies are in drought.

There is currently little to no snow pack in northern Alberta, and Natural Resource Canada's fire forecast severity rating for Mayis already at a high to extreme level in much of Alberta and Saskatchewan, as well B.C.'s Southern Interior.
