The snowpack in the Okanagan is continuing on a downward trend, though still sits at slightly higher levels than average.

The latest report by the River Forecast Centre, released May 8, shows the Okanagan region㽶Ƶֱs snowpack at 110 per cent of normal, down six points from the previous report released in April.

Jonathan Boyd, a hydrologist with the River Forecast Centre, said barring some extreme, record-setting rain, flooding from Okanagan Lake is extremely unlikely this year.

Although some areas are higher than others 㽶Ƶֱ Mission Creek was a concern brought up by Boyd, which currently sits at 146 per cent of the normal snowpack.

㽶ƵֱThere㽶Ƶֱs still quite a bit of snow in the upper watershed there,㽶Ƶֱ said Boyd. 㽶ƵֱThe biggest risk would be to have four or five days of extreme heat melting the snow than having a big rain system fall through right afterwards.㽶Ƶֱ

Boyd said he was a little bit concerned for the Okanagan around February when the snowpack sat at around 130 per cent, but it has since subsided significantly.

㽶ƵֱSince then, it㽶Ƶֱs been relatively dry overall,㽶Ƶֱ he said. 㽶ƵֱThere hasn㽶Ƶֱt been much snow accumulation in the Southern Interior. I㽶Ƶֱd suggest that its a pretty good situation for the Okanagan to be in.㽶Ƶֱ

Even then, that number was nowhere close to what was seen in 2017 and 2018, when the snowpack hit 147 and 206 per cent of normal levels respectively.

㽶ƵֱDefinitely not as bad as it was two years ago or as wet as it was three years ago,㽶Ƶֱ said Boyd.

As the snowpack tends to reach its maximum level in mid-April, no significant increases are anticipated.

The provincial average of snow measurements is 106 per cent of normal.

Seasonal flood risk is elevated in many regions, including the Upper Fraser East, North Thompson, South Thompson, West Kootenay, Boundary, Cariboo Mountains, Central Coast and Similkameen.
