Kelowna’s Mission Creek is now on flood watch following a sustained period of heavy rain, according to the River Forecast Centre.

A Water Survey of Canada gauge measured a “rapid increase overnight” with flows on the creek near East Kelowna measuring 56 cubic metres per second.  The B.C. River Forecast Centre said that additional rises of up to 80 to 100 cubic metres are possible Monday into Tuesday, depending on additional rainfall amounts.

It’s been a soggy start to July, with five to 35 mm of rain falling throughout the Southern Interior since Sunday.

While Mission Creek is the only river on a flood watch, other waterways may also see a rise in flow depending on how much rain falls.

“Given the uncertainty in the exact locations and intensity of rainfall, it is possible that small and medium-sized watersheds throughout the region may experience high flows on Monday and Tuesday,” the forecast centre said.

Okanagan streams, other than Mission Creek, are also only on an advisory.
