Environment Canada has issued a rainfall warning for parts of Metro Vancouver as well as the lower Sunshine Coast and Howe Sound regions.
The weather agency says a frontal system that's "unseasonably" laden with moisture is expected to cross British Columbia's south coast on Friday.
It says the system is forecast to bring strong winds and rain that will become heavier throughout in the day, with up to 80 mm expected at higher elevations.
The bulletin says the rain is expected to taper off in the late evening on the Sunshine Coast and after midnight across eastern Metro Vancouver.
Environment Canada is warning about the potential for limited visibility during the downpours, which will be heaviest during Friday's afternoon commute.
The agency says water pooling on roadways will raise the risk of hydroplaning.
The rains could also cause water levels in rivers and creeks to rise rapidly, and anyone in or around waterways is advised to stay alert.
