“A strong warm front will bring a lot of moisture and increasing snow level to southern B.C. today and tonight,” said Environment Canada.

“The trailing cold front will move across the region from the northwest to southeast on Wednesday, lowering the snow level and producing more snow over the highway passes.

“As the snow level can change significantly between different locations, the exact timing and snowfall amounts will vary.”
