The City of Port Coquitlam posted a notice on November 5, 2026, about a Yellow Warning for Rainfall from Environment Canada and a High Streamflow Advisory from the BC River Forecast Centre. In an update dated November 6, the City said both remained in effect and that it continues to monitor and respond to conditions as needed.
According to the City, heavy rain was expected to begin after midnight on the night of the original notice and continue through Friday. The City described it as the first storm in a series of wet and windy weather ahead.
The City says it has been clearing catch basins and sweeping streets, inspecting culverts, positioning equipment and monitoring conditions.
For residents, the City suggests helping clear fallen leaves from storm drains in their neighbourhood, allowing extra travel time and driving with care, and staying clear of fast-flowing rivers, creeks and potentially unstable riverbanks. It also recommends having flashlights ready and devices charged.
