Environment Canada has issued a special weather statement for Howe Sound.
A series of vigorous frontal systems will move across the south coast on Tuesday night and will be active until Saturday.
Periods of heavy rain and strong winds can be expected in the first active storm cycle of the fall season.
The heaviest rainfall amounts are currently expected over Howe Sound and the North Shore.
The first system arrives on Vancouver Island tomorrow and will spread to the mainland before Wednesday morning and will continue through Thursday.
For the mainland, total rainfall amounts will range from 50 mm to excess of 100 mm over the two day period.
Over Vancouver Island, total rainfall amounts over the two day period will generally range from 15 to 40 mm, with amounts excess of 100 mm over West Vancouver Island.
This system will also bring strong southeast winds to the west coast of Vancouver Island on Tuesday night, with winds of 60 to 80 km/h.
As the system progresses, winds across the Strait of Georgia and surrounding regions will peak early Wednesday morning at 50 to 70 km/h.
The combination of heavy rain with leaves on the ground may lead to localized flooding, and strong winds may also lead to power outages, Environment Canada warns.
The wet pattern will continue and more rain can be expected on Friday and Saturday.
