Environment Canada is continuing its Special Weather Statement for most of the BC Interior through the week, including the Boundary, West Kootenay regions.

Environment Canada said that unseasonably hot weather will continue with daytime highs rising to the low to mid 30’s over the central and southern interior while the northern regions will see the thermometer reaching the mid to high 20s.

“The BC Interior is experiencing unseasonably hot weather due to a strong ridge of high pressure,” Environment Canada said.

“The highest temperatures are expected through Tuesday. Daytime highs will be 10 to 15 degrees Celsius above seasonable values while overnight highs will be 5 to 10 degrees above what is normally experienced this time of year.”

Environment Canada said the ridge of high pressure will gradually weaken later this week allowing daytime highs to drop a couple of degrees later in the week.

However, Environment Canada said, that the temperature will remain higher than seasonal values.

Environment Canada said the freezing level will remain near 4000 meters throughout the week, leading to an increase of snowpack melt which could lead to possible flooding due to high stream flows.

The BC River Forecast Centre issued a High Streamflow Advisory for the Upper Columbia, Boundary, Kootenay on Sunday. The Boundary region includes the Kettle River, Granby River and surrounding tributaries.

“Snowmelt rates have been increasing over the past two days,” the BC River Forecast Centre website said.

” In mid-elevation terrain, snowpacks are dwindling, however significant upper elevation snow still remains.”

The BC River Forecast Centre said rivers have begun rising, and a continued rising trend in river levels is expected throughout the week.

“Areas with higher elevation terrain, including Ktanaxa Territory, West Kootenay and East Kootenay regions are expected to reach higher flows than have been experienced earlier this season,” said the BC River Forecast Centre.

“In the Boundary Region and Syilx Territory, flows are expected to rise through the week, however with dwindling snowpack there is uncertainty whether flows will exceed levels previously experienced earlier in May.”

Despite the rise in the temperature, Environment Canada said the expected hot conditions will not approach those reached during the June 2021 Heat Dome.
