Coquitlam sits in coastal British Columbia, where a mild oceanic climate brings Canada’s heaviest rainfall totals, driven largely by atmospheric rivers of moisture that arrive off the Pacific through autumn and winter.
In the mountains northeast of Vancouver, the city’s steep terrain can send heavy coastal rain into local creeks very quickly. These atmospheric river events, including the catastrophic November 2021 storm that caused widespread flooding and landslides across the region, can drop extraordinary rainfall totals in just a few days, making radar an essential tool alongside Environment Canada’s official warnings.
