Environment Canada is predicting a rainy, windy day for most of Vancouver Island, with alerts for high wind and rainfall issued.
On the West Island, a Pacific frontal system is overhead and producing heavy rainfall, with nearly 100 mm expected by the evening.
Localized flooding is possible in low-lying areas, with flash floods and water pooling on roads caused by heavy downpours.
The North Island continues to be under a wind warning with speeds up to 90 km/h, potentially tossing loose items and breaking branches.
Winds on the North Island are expected to ease by the afternoon.
People on the East Island are getting a mix of both wind and rain, with Southeast winds between 60 to 80 km/h over exposed coastal sections of the Island and the Sunshine Coast.
The winds have already forced a number of ferry cancellations on major and smaller routes.
Rainfall is expected to reach about 50mm by Wednesday evening on the East Island, easing to scattered showers at night.
Alerts are posted on the Environment Canada website. People who witness extreme weather events are encouraged to tweet updates using the hashtag #BCStorm.
