B.C.’s River Forecast Centre has issued a high streamflow advisory for Vancouver Island, which means minor flooding in low-lying areas is possible.
All of Vancouver Island is covered by this high streamflow advisory, due to the large amount of rain that fell Monday.
According to Environment Canada, Port Alberni had the most precipitation on the Island with 61.5 mm of rain.
Tulameen River and tributaries and Coldwater River and tributaries of the Nicola River downstream from Merritt, including Spius Creek are also under a high streamflow advisory.
South Coast, including the Sunshine Coast, Howe Sound, North Shore Mountains, Lower Mainland including Metro Vancouver and Lower Fraser Valley, including up to Hope and the Coquihalla Summit, and neighbouring basins are under a flood watch, which means river levels are rising and will approach or may exceed bankfull.
“River levels are expected to rise quickly beginning on Monday in areas receiving the brunt of the storm with flows peaking Tuesday into Wednesday,” the River Forecast Centre says in a notice.
“Current forecasting is suggesting that flows are expected to be highest for West Vancouver Island, the North Shore Mountains, and the Lower Fraser Valley, however this could shift into nearby areas if higher than forecasted rainfall occurs in other areas.”
