Environment Canada issued snowfall warnings for Banff, Canmore and surrounding areas on Wednesday afternoon.

"An area of snow is moving through the Lake Louise and Kananaskis regions," the agency said in a release.

"Higher elevations have the potential to see accumulations of 10 to 15 centimetres before snow tapers off this evening."

Snow began falling in Calgary in the late afternoon, and Environment Canada forecast accumulations of two to four centimetres. It said the snow would taper off in the evening.
