An 'Atmospheric River' In BC's 2 Most-Populated Regions Could Cause Flash Floods

An "atmospheric river pattern" could bring flash floods and localized flooding to some of B.C.'s most populated regions.

Environment Canada has issued a weather warning for high amounts of rainfall across Metro Vancouver and the Greater Victoria area for Wednesday night through Thursday, October 28.

Rainfall totals of 50-70 millimetres are predicted for the North Shore mountains, eastern sections of Metro Vancouver, and the Fraser Valley, while the Greater Victoria area is expecting 50 millimetres.

Environment Canada says the weather system will clear from Victoria on the evening of October 26 as the system moves into the B.C. Interior, where it could dump large amounts of snow over the Rocky Mountains.

If you're ready for the wet weather to end, the Farmer's Almanac doesn't have great news in its November long-range forecast, either.
