Rainfall warning in effect until Sunday in Metro Vancouver

Environment Canada has issued a rainfall warning for parts of central Metro Vancouver, extending into Sunday afternoon.

1130 Meteorologist Michael Kuss says there will be some heavy periods during this atmospheric river over the weekend, but he 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.

“Now there will be some periods it looks like this evening where it won’t be raining quite as steadily, but expect 30 millimetres through the day on Saturday, and another 10 to 25 mm of precipitation overnight.”

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.”
