Atmospheric river approaching B.C.’s South Coast, Vancouver Island: officials [Video]

B.C.’s River Forecast Centre has issued a high streamflow advisory for parts of Vancouver Island and the South Coast due to an incoming atmospheric river.

An atmospheric river is a large, narrow stream of water vapour that travels through the sky.

Areas of the province will be drenched from Friday night through Sunday, according to officials. West Vancouver Island could get 150 to 200 mm of rain and the South Coast Mountains could get 100 to 200 mm. 

The centre says it doesn’t know which areas will be hit the hardest. It said runoff and streamflows will likely start to increase Friday night, starting on North Vancouver Island and proceeding south as the storm moves through the region.
