Rainfall Warning Issued for Inland Vancouver Island as Atmospheric River Persists

Alert Details

Environment Canada has issued a yellow rainfall warning for Inland Vancouver Island. This alert is in response to a prolonged atmospheric river event currently impacting the South Coast of British Columbia, characterized by high freezing levels and heavy precipitation.

Affected Areas

The warning specifically covers Inland Vancouver Island. Impacted regions include northern sections such as Gold River, as well as southern sections including Port Alberni and Lake Cowichan.

What You Should Do

Residents are advised to monitor local alerts and forecasts issued by Environment Canada. Water is likely to pool on roads and in low-lying areas, which may cause travel delays. Landslides may occur in vulnerable areas such as steep slopes, deforested areas, or recent burn scars. Residents should stay away from fast-moving and rapidly rising water, which can sweep vehicles away and damage infrastructure. To report severe weather, email BCstorm@ec.gc.ca or post reports on X using #BCStorm.

Expected Conditions

Total rainfall amounts from Sunday to Wednesday morning are expected to reach near 100 to 150 mm over northern sections (Gold River) and 50 to 70 mm over southern sections (Port Alberni and Lake Cowichan). Freezing levels will remain between 2000 to 3000 metres, causing mountain snowmelt. The combination of heavy rain and snowmelt could lead to enhanced responses in river systems and potential flooding. Extensive water pooling on roads and washouts may occur, along with an enhanced risk of landslides due to saturated landscapes.

Timeline

The atmospheric river will remain over the region through Friday. Rain is expected to intensify this evening and briefly ease Wednesday morning. Periods of moderate to heavy rain will continue from Wednesday afternoon through Friday. The heaviest rainfall is currently forecast for Thursday night into Friday.
