A special weather statement has been issued for Howe Sound.
A wet and windy beginning to the weekend is in the forecast with rainfall totals that could reach 75 to 150 mm over two days.
This warning also applies to western and mountainous sections of Vancouver Island, Sunshine Coast near Sechelt and Gibsons, and the Fraser Valley.
Eastern sections of Vancouver Island near Bowser may also be affected.
The alert is for Friday morning to Sunday morning.
Two successive frontal systems will cross the south coast Friday through Sunday, with high water content associated with an atmospheric river flowing from the southwest off the Pacific Ocean.
High southeasterly winds will also accompany this weather event. As freezing levels rise over 2000 metres on Saturday, snow melt will also add to run off.
Swelling of local streams and localized flooding are possible during this time.
There is a fair amount of uncertainty with the timing and location of these two systems, and how long the break will be between them, if any.
Warnings will likely be issued closer to the event and for fewer areas than are covered by this statement.
