The national agency said a weather system stalled over the city, dumping heavy snow on the region.
As of 8 a.m., five to eight centimetres had fallen across an area between Leduc in the south and Barrhead in the north, and another five centimetres was expected by Wednesday afternoon.
The warning stretched from the Athabasca area in the north to the Leduc, Camrose, Wetaskiwin and Tofield areas in the south. It also included Parkland and Yellowhead counties in the west and the Fort Saskatchewan, Vegreville, Redwater and Smoky Lake areas to the east.
The band of snow moved slowly east throughout the afternoon, leaving behind approximately 10 centimetres of snow, Environment Canada said.

Residents were encouraged to prepare for quickly changing and deteriorating travel conditions, as visibility could be suddenly reduced at times in heavy snow.
Edmonton police said between 5 a.m. and 4:30 p.m., there were a total of 146 collisions in the city — eight of which caused injuries and 15 that were hit and runs.
A seasonal parking ban went into effect Wednesday morning, and the city said it was in a good situation and well-prepared to deal with the snow.
Graders and sanders were out overnight and would continue their work through the day.
The city was hoping to lift the parking ban by the end of the week, however it could be extended in light of Wednesday’s snowfall.
Rapidly accumulating snow could make travel difficult over some locations.
