Unsettled weather in British Columbia causes flash flooding, complicates river level forecasts

Prince George is the latest city to feel the brunt of heavy rains associated with continued unsettled weather in British Columbia.

Environment Canada reported about six millimeters of rain fell at Prince George’s Airport on Tuesday, but did not mention the localized, intense thunderstorm that drenched the downtown area, flooding several streets.

The RCMP said its frontline officers had to help after “several vehicles” were stuck in the water in the industrial area off Queensway and Winnipeg Street. Four separate roads were closed while crews worked to clean up excess water.

Similar torrential rain forced officials in Penticton to briefly declare a local state of emergency Monday as a flash rainstorm over the Okanagan town caused flash flooding and forced the evacuation of 16 properties.

The River Prediction Center has since downgraded the level of Mission Creek from a flood watch to a high flow warning as levels in that waterway in the Kelowna area drop, but advisories remain in place for much of southeast and southern B.C. Columbia, including the Fraser River from Quesnel to the ocean.

Flood watches cover sections of the Thompson, South Thompson, Chilcotin and Nechaco rivers, and a flood warning is still in effect for portions of the Quesnel River near Quesnel.

In the Lower Mainland, an evacuation warning for Barnston Island in the Fraser River near Surrey was lifted on Wednesday. Water levels in the river have dropped enough to reduce the risk of flooding, officials said.

Environment Canada is calling for thunderstorms throughout the day for many regions of British Columbia, and forecasters say that creates the potential for more localized flooding, but the exact locations and intensity of rainfall are uncertain.
