Environment Canada had issued a rainfall warning for parts of central Metro Vancouver this weekend, but this is expected to ease Sunday while the deluge moves on to Sea-to-Sky country.

1130 Meteorologist Michael Kuss says that region could see between 50 to 60 millimetres of precipitation.

Meanwhile, he says a snowfall warning has been issued for the Coquihalla, with 15 to 20 centimetres expected. Environment Canada says this will start Sunday morning and taper off Monday.

“Rapidly accumulating snow could make travel difficult over some locations,” the weather agency said. “Visibility may be suddenly reduced at times in heavy snow.”

Metro Vancouver is dealing with some heavy periods of rain during this weekend’s atmospheric river, but Kuss says the big story is the precipitation’s duration.

“It lasts all day Saturday through the overnight and a good chunk of Sunday too,” Kuss said.

Through until Sunday morning, Pitt Meadows has seen almost 33 mm and Coquitlam has had 40 mm. Spots around North Vancouver received around 50 mm of rain and West Vancouver got around 43 mm.

Another 15 to 25 mm is expected throughout the day on Sunday.

Kuss says the heaviest rain will fall closer to the mountains and the coast.

“Rainfall warnings from the city of Vancouver through Burnaby and New West onto the North Shore and out to the Tri-Cities, Pitt Meadows, and Maple Ridge as well, where we’ll likely see, over the two days, Saturday and Sunday, 75 plus mm of precipitation amounts will be lower farther to the south,” he said.

“Right up against the hills could touch 100 mm over that two-day stretch.”
