Environment Canada forecast the rain would begin in Metro Vancouver and the Fraser Valley Saturday afternoon and intensify around midnight.

“Rain will remain heavy at times during the overnight hours and during the day on Sunday,” the national weather and climate agency said.

“The rain-snow line is expected to be just above Squamish tonight then progress beyond the Tantalus overlook to just south of Brandywine early Sunday,” Environment Canada said.
