A Pacific storm expected to sweep through B.C. this weekend could have an impact on travellers during the busy holiday season.

The storm is forecast to begin pushing a warm front inland around midnight, bringing with it plenty of precipitation, snow and high winds in parts of the province.

Environment Canada has issued wind and rainfall warnings for parts of B.C.

Metro Vancouver is warned to expect up to 70 mm of rain by Saturday evening, according to Environment Canada. Parts of the South Coast, eastern Vancouver Island and the Fraser Valley are expected to get about the same amount of rain.

CBC meteorologist Johanna Wagstaffe said temperatures will hit the double digits in Vancouver this weekend, but the alpine levels of Whistler will likely continue to see snow.

Environment Canada also said highway passes in B.C.'s Interior are forecasted to get significant snowfall, with about 10 to 15 cm expected at Coquihalla and Allison passes, and about 15 to 20 cm at Kootenay Pass. Rogers Pass is expected to see about five to 10 cm of snowfall.
