Environment Canada has published a special weather report For the south coast of British Columbia, heavy rain and strong winds are forecast, which should begin Sunday and continue until Monday afternoon.

The storm is expected to impact Metro Vancouver, the Fraser Valley, Howe Sound and the Sunshine Coast, with rainfall totals between 30 and 40 millimeters by Monday morning.

The weather agency warns that the storm could cause reduced visibility, washouts near rivers, streams and culverts, as well as potential power outages if high winds cause branches to fall on power lines.

Residents are advised to clear storm drains of leaves and debris to help prevent localized flooding.

This special statement is the latest in a series of weather warnings for the South Coast this fall. This follows an intense atmospheric river event on October 19, which led to at least four deathsand a wind storm earlier this week which left thousands of people without electricity.

The BC River Forecast Center also published a high flow notice for the South Coast and parts of Vancouver Island, warning that rivers could see increased flow due to recent wet weather.

According to the advisory, the current storm will be followed by a second weather system expected Tuesday through Wednesday, which could bring additional heavy precipitation.

A high flow advisory indicates that river levels could rise rapidly, but no major flooding is expected. Authorities are urging caution near fast-flowing rivers and warning that conditions could change as storms progress.

The center notes that while rivers on the South Coast and Vancouver Island are currently at “near normal” levels for this time of year, recent precipitation could make the region’s rivers more vulnerable to rapid increases.

Environment Canada and the River Forecast Center say they will continue to monitor the situation and further updates are expected if conditions deteriorate.
