Another 'juicy' atmospheric river rainstorm on its way to B.C.'s South Coast

British Columbians living on the South Coast can expect yet another downpour this weekend, withanother atmospheric river-fuelled storm set to pummel most of the region.

Environment Canada has special weather statements in effect for Metro Vancouver, Howe Sound, the Sunshine Coast and the Fraser Valley. Up to 150 millimetres of rain is expected from Saturday night to Monday morning.

"This is certainly a juicy system, there's no doubt about it ... this is a pretty wet system, as they go," said meteorologist Bobby Sekhon.

The rain is expected becausetropical moisturelinked to theatmospheric river from the Pacific is heading for B.C. The storm isalso expected to drive the freezing levels higher, meaning snowy mountaintops on the North Shore will see rain and melting snow instead.

All of that water could result in flooding and high river levels.

The stormis the second so-called atmospheric river to sweep over B.C. in the past four weeks.It's expected to manifestas snow in the Boundary region, East and West Columbia, Kootenay Lake and the West Kootenay.

Up to 20 centimetres of snow is expected for those areas before ending on Sunday morning.

Sekhon said atmospheric rivers aren't unusual for the month of November, but fall this year has been rainier than usual.

"November is the wettest month of the year ... however, it almost seems like November started in September this year," he said.

"Rain started in September and really hasn't let up too much all the way through."

Sekhon said people should clear storm drains in front of their homes before the rain hits.
