Municipalities by the North Shore Mountains will see the highest amount of rainfall, Environment Canada reports.
The Sunshine Coast will also be impacted between Gibsons and Earls Cove.
The federal department warned that flash flooding and water pooling on roads may be a possibility.
This rainfall warning includes the rain expected from just the first part of this “intense frontal system.”
Its cold front will cross the region late Wednesday into Thursday morning and could bring yet another 20 to 30 mm of rain.
This is the second of a series of five frontal systems which will hit the South Coast this week.
The first hit the region Monday night with periods of heavy rain and there will be very few breaks right through next Monday.
Environment Canada also issued a heavy rainfall warning for west Vancouver Island on Tuesday.
Between now and Wednesday morning, it projects between 90 and 110 mm may fall before the system subsides into scattered showers.
If visibility is reduced on the roads, the department is reminding drivers to turn on their lights and maintain a safe following distance.
