B.C. braces for more flooding as heavy rain forecast across Fraser Valley and Vancouver Island

The B.C. government is warning that heavy rain expected across parts of the province could lead to additional flooding in low-lying areas. Authorities say the Sumas and Chilliwack Rivers remain under flood warnings, though rainfall is anticipated to be less severe than last week’s storms that caused extensive flooding in Abbotsford.

Environment Canada has issued "high impact" rainfall warnings for the Fraser and Skagit valleys, with some areas expected to receive up to 80 millimetres of rain, particularly in higher elevations. Officials cautioned that the situation is unpredictable and that some highways may need to close on short notice, including Highway 5, the Coquihalla, Highway 1 through the Fraser Canyon, and Highway 99 from Cache Creek to Pemberton.

While Highway 1 was reopened in both directions over the weekend, dozens of properties remain under evacuation orders, and hundreds more are on alert following flooding across the Sumas Prairie last week. Abbotsford’s mayor and fire chief said they are monitoring conditions closely and continue to prioritize public safety.

Vancouver Island is also expected to see significant rainfall, with authorities warning of possible landslides and falling trees along Highway 4, Bamfield Road, and other routes. Residents are being urged to stay alert and follow official guidance.

Rainfall warnings have been issued across much of the province, including Metro Vancouver, the Fraser Valley, Howe Sound, and coastal regions, highlighting ongoing flood and landslide risks.
