A rainfall warning is in effect for the Lower Mainland.
Issued by Environment Canada early Thursday, the warning stretches from Howe Sound through Metro Vancouver to the Fraser Valley.
The national weather agency is calling for rainfall amounts nearing 50 millimetres, spanning from Thursday afternoon through to early Friday morning.
“A developing Pacific frontal system will spread rain into the Lower Mainland late this afternoon,” Environment Canada said in its warning, adding that localized flooding in low-lying areas is possible, and that people should watch out for possible washouts near rivers, creeks and culverts.

Of note, a secondary wave of moisture appears to be in the forecast Sunday through Monday, with even larger rainfall totals.
The systems will also produce heavy rain on the North Shore mountains and the Coquihalla Highway as the freezing level rises.
