BRITISH COLUMBIA

Category 4 Atmospheric River brought extreme rainfall totals this weekend to the South Coast of British Columbia and part of the Southern Interior causing widespread power outages (approx. 10,000 customers lost power) and significant flooding which led to road washouts/compromised infrastructures, rockfalls, and landslides; flood waters engulfed streets from ponding to fast-moving water laden with debris. This follows three years of consecutive drought; parching the landscape and weakening trees.

12 new Daily Rainfall Records were set in Victoria, Squamish, Vancouver, West Vancouver, White Rock, Langley, Abbotsford, Chilliwack, Hope, Nakusp, and the Agassiz and Pitt Meadows areas. Most notably, West Vancouver where 134.6 millimetres of rain fell in one day, smashing the record of 34.8 millimetres set in 1970.

Accumulated rainfall in many areas were upwards of 300mm with a few areas recording totals over 300 mm.

COQUITLAM LAKE - WQA Oct 19 Metro Vancouver Regional District issued an advisory due to extreme rainfall on the steep, mountainous terrain above the Coquitlam Reservoir has caused turbidity or cloudiness in the drinking water for residents in the eastern portion of Metro Vancouver. The district had increased levels of treatment and disinfection as a safety precaution, and the medical health officer for the region was confident the water remains safe to drink despite its cloudy appearance.

MISSION – FLOOD Oct 20 Activated its Emergency Operations Centre to address major flooding, downed trees, and road closures as a result of a Category 4 Atmospheric River. The City says plans are in place to move people across the flooded area for emergency purposes and urges residents to stay home if possible and to avoid entering storm water.

NORTH VANCOUVER – FLOOD Oct 20 Due to significant weather event causing severe flooding across the district, the District of North Vancouver declares state of local emergency and issued a mandatory evacuation order for six properties in Deep Cove due to the risk of impacted private infrastructure following significant rainfall; a sinkhole has developed in the area. Also, one of the retaining walls in the neighbourhood has been damaged from being overcome by water.

In the Woodlands community approximately 80 homes were isolated when their access road was washed out.

Short-term emergency supports are in place for residents who have experienced significantly impacted due the storm system.
