Fraser Valley – It’s gonna be wet. Fall rain storms are nothing new but this one has flood potential:
6:25 AM PDT Thursday 14 October 2021
Special weather statement in effect for:
- Fraser Valley – central including Chilliwack
- Fraser Valley – east including Hope
- Fraser Valley – west including Abbotsford
A wet and windy beginning to the weekend is in the forecast.
Rainfall totals could reach 75 to 150 mm over two days.
Locations: Western and mountainous sections of Vancouver Island, Sunshine Coast near Sechelt and Gibsons, Howe Sound, 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. 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.
