Flood and fire risks remain as temperatures rise across much of B.C.

Unseasonably hot temperatures in British Columbia will persist over the coming days, with special weather statements from Environment Canada warning of high river streamflows due to melting snow in hard-hit communities in the province’s interior.

The weather agency’s statements covering the region warn of daytime temperatures anywhere from 10 to 15 degrees above seasonal norms.

Vernon reached 30.0 degrees C on Saturday while Kelowna was at 31.0. It’s not known if either of those were records.

“The B.C. Interior is experiencing unseasonably hot weather. The highest temperatures are expected from today through Tuesday. Daytime highs will be 10 to 15 degrees Celsius above seasonal values while overnight lows will be 5 to 10 degrees above what is normally experienced this time of year,” an advisory from Environment Canada stated..

Saturday saw several heat records shattered across B.C., with many communities breaking or tying daily maximum temperature marks.

Agassiz saw temperatures of 31.6 C, topping the record of 31.3 C set in 2018.

Fort Nelson set a new record of 28.1 C, breaking the old one of 25.6 C set in 1973.

Temperatures at the Squamish Airport reached 32.4 C, beating the previous record of 29.6 C seen in 2018.

Environment Canada meteorologist Louis Kohanyi said Sunday that the high temperatures are unusual for this time of year, but don’t compare to the heat dome event of June 2021.

“It is a different scenario,” he said. “The heat dome of June 2021, it was really exceptional.”

Kohanyi said the province is still grappling with fire and flood risks in certain areas as the snowpack melts and dry conditions persist, which also elevate the risk of heat-related illnesses.

Environment Canada’s special weather statements for Metro Vancouver and the B.C. interior remain in place while some communities are still dealing with earlier flooding and newly sparked wildfires.

The Peace River Regional District says the region saw “significant fire activity” on Saturday, issuing evacuation orders for dozens of properties in the vicinity of the Stoddart Creek wildfire due to what it calls an immediate danger to safety.

The district also issued an evacuation order for the area around the Donnie Creek and Tommy Lakes wildfire, though it says the area is sparsely populated and mainly used by forestry and oil and gas workers.

The provincial River Forecast Centre issued high streamflow advisories for the Dean and Bella Coola rivers warning of rapidly rising waters, but major flooding isn’t expected.

The centre’s high streamflow advisory for the Upper Columbia, West Kootenay, East Kootenay, and Boundary River also includes the Kettle River, Granby River and surrounding tributaries.

“Snowmelt rates have been increasing over the past two days. In mid-elevation terrain, snowpacks are dwindling, however significant upper elevation snow still remains. Rivers have begun rising, and a continued rising trend in river levels is expected throughout the week,” the advisory says. “However with dwindling snowpack there is uncertainty whether flows will exceed levels previously experienced earlier in May.”

In a flood update Saturday, the Village of Cache Creek says it fixed a water main issue that spurred water restrictions, but kept a boil water advisory in place as sidewalks and roads are still strewn with debris from earlier flooding.
