A weather alert for heavy snowfall on the Coquihalla Highway has been upgraded to a winter storm warning.

On Saturday, Environment Canada said an incoming Pacific system would bring an estimated 20 to 40 cm of snow beginning later Sunday.

On Sunday morning, though, the national weather agency changed the special weather statement to a winter storm warning, saying 25-40 cm is expected. It also told motorists to consider postponing non-essential travel until conditions improve.

“Light snow is expected to intensify overnight with lowering snow levels. Snow at times heavy will continue through Monday and taper off to a few flurries Tuesday afternoon.”

Meanwhile, a winter storm watch issued on Saturday for a portion of Highway 3 was also upgraded on Sunday morning to a winter storm warning.

Environment Canada’s updated forecast predicts 25 to 35 cm of snow between Paulson Summit and Kootenay Pass. The snow is expected to start later Sunday before easing late Monday afternoon.

The distance between the two passes is around 115 kilometres.
