Environment Canada has issued yet another rainfall warning for Metro Vancouver.
This one takes effect tonight (January 31) through to Saturday (February 1) morning.
What the government agency describes as an "intense low pressure system with subtropical moisture" has already dropped 40 to 80 mm of rain on the South Coast regions since Thursday night (January 30).
Now a following cold front associated with the system is expected to dump up to another 50 mm of rain on parts of Metro Vancouver.
The alert includes Vancouver, Burnaby, New Westminster, the North Shore, Richmond. Delta, Coquitlam, Maple Ridge, Langley, and Surrey.
The warning advises that such heavy rainfall can cause flooding in low-lying areas, flash floods, water pooling on roads, and possible washouts near streams, rivers, and culverts.
