Over the next three days, a large storm system will be moving through much of western and central Canada, bringing rain, snow and gusty winds to some communities.

Snowfall warnings are in effect for parts of B.C., along with rainfall warnings in Alberta and high water alerts in Manitoba, which has been preparing for spring flooding all week.

TIMING

"Rain will develop Tuesday night over Alberta and southern Saskatchewan, spreading into southern Manitoba Wednesday," says Weather Network meteorologist Doug Gillham.

"Snow will move into northeastern B.C. during the predawn hours Wednesday, lasting through to Thursday morning."

WHAT TO EXPECT

B.C.: Up to 25 cm of snow, along with up to 40 mm of rain, is expected in northeastern portions of the province, with the central and southern Rockies seeing up to 15 cm of snow.

Alberta: "Rain will continue through Wednesday, likely changing to wet snow before ending," Gillham says. "Wind gusts between 60 and 80 km/hour are likely."

Up to 40 mm of rain could fall by the time all is said and done. Calgary will likely see closer to 10 mm, while Edmonton to Whitecourt could receive up to 60 mm of rain. Up to 15 cm of snow could fall in the Foothills.

Saskatchewan and Manitoba: Between 20 and 40 mm of rain is forecast for southern Saskatchewan and Manitoba, with up to 5 cm of snow possible in Prince Albert, SK and up to 10 cm between Dauphin and Swan River, MB. Wind gusts up to 80 km/h will impact some communities.

Officials in Manitoba say they're keeping a close eye on the coming storm and will be assessing the impact of the rainfall continuously.

"There are many factors that contribute to spring flooding, and rainfall is just one of them," says Weather Network meteorologist Gina Ressler.
