Surrey 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 Fraser Valley in British Columbia, the city sits in an area affected by the catastrophic November 2021 floods that followed an atmospheric river storm. 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.
