Another atmospheric river that will bring heavy rain and snow to the south coast of British Columbia, the central hinterland.

“A severe storm hit the coast of British Columbia. It will pass through the province in the next day and a half,” Global BC chief meteorologist Mark Madriga said on Thursday.

“We’ll probably end up in the Lower Mainland with 40 to 80mm of rain before we finish late tomorrow night.”

It is predicted that rain will fall along the entire coast during the day on Thursday, then intensify into the evening and Friday, and finally decrease by the end of the day.

Freezing levels will also drop to 300 meters on Thursday, Madrigi forecast, meaning light snow is likely in areas like Burnaby Mountain and the Westwood Plateau in Coquitlam before milder subtropical air flows with the atmospheric river on Friday, said Madriga.
