The B.C. River Forecast Centre has issued a high streamflow advisory for various regions along the British Columbia coast, encompassing the south and north coasts, north and west Vancouver Island, and Haida Gwaii. This advisory indicates an imminent rise in river levels, potentially leading to minor flooding in low-lying areas, although significant flooding is not anticipated.
Forecasters anticipate the impact of several atmospheric rivers affecting the B.C. coast over the upcoming weekend and into the following week. The forecast center’s bulletin highlights the likelihood of prolonged periods of moderate to heavy rainfall, warmer temperatures, and increased runoff from rain-on-snow melt.
The period of heaviest rainfall is expected from Saturday to Sunday for the North Coast, Haida Gwaii, Central Coast, and Vancouver Island, while the South Coast and Lower Mainland are likely to experience intense rainfall from mid-day Sunday through Monday. Peak river levels are predicted to occur over the weekend in northern regions and from Sunday to Monday on the Island and South Coast.
Emergency Info B.C. urges residents to exercise caution near fast-flowing rivers and unstable riverbanks during this period. Additionally, Environment Canada has issued rain and wind warnings for parts of the North Coast, including Prince Rupert, Kitimat, and Terrace, with rainfall amounts ranging from 50 to 100 millimeters and strong winds of up to 120 km/h expected in certain coastal sections.
Residents are advised to prepare for potential power outages, secure loose objects, and avoid contact with fallen power lines. Heavy snowfall may also affect inland areas on the North Coast, such as Stewart, transitioning into rain as the weekend progresses.
