A wet and windy beginning to the weekend is in the forecast.
Total rainfall amounts could reach 75 mm except up to 150 mm over west Vancouver Island and Inland Vancouver Island.
Locations: Western and mountainous sections of Vancouver Island, Sunshine Coast near Powell River, Whistler, Metro Vancouver and the Fraser valley especially near the mountains, in communities such as Mission. Eastern sections of Vancouver Island near Bowser may also be affected.
Timespan: Friday morning to Sunday morning
Remarks: 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. Strong southeasterly winds of 40 to 60 km/h near the water 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.
For the regions in the special weather statement, 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.
Rainfall warnings have been issued for the regions where confidence is high. Further warnings could be issued closer to the event.
