Environment Canada has issued a rainfall warning for Metro Vancouver and the Fraser Valley.
A total of 50 to 70 millimetres is expected to fall throughout the day (Jan. 30), with 30 to 50 millimetres expected before evening when the system will taper off into a few showers.
The downpour will lead to poor travel conditions, and the possibility of localized flooding in low-lying areas, Environment Canada says.
“If visibility is reduced while driving, turn on your lights and maintain a safe following distance,” the warning says. “Watch for possible washouts near rivers, creeks and culverts.”
