Forecasters are warning of swollen creeks and rivers as heavy rain sweeps through southern British Columbia.
High-flow warnings have been issued for the entirety of Vancouver Island, along the south coast and in the interior south, warning that rivers may rise rapidly and pose a threat to public safety.
Environment Canada said a Pacific frontal system washed over Vancouver Island and the South Coast over the weekend brought up to 90 millimeters of rain to Haida Gwaii and more than 80 millimeters to Saturna Island.
Streams and rivers on Vancouver Island, the Lower Mainland, the Fraser Valley and Howe Sound are expected to rise Monday, with localized flooding possible, the River Forecast Center said.
Environment Canada is warning residents in southeastern British Columbia, from the border region to West Kootenay and East Kootenay, to expect up to 50 millimeters of rain before weakening on Tuesday.
River forecasters said the region’s smaller, lower-elevation creeks and rivers were most at risk of flash flooding due to remaining snow.
“These rain and snow events have significant uncertainty based on fluctuations in rainfall totals, maturity of snowmelt, and freezing levels,” the center said in its advisory.
