Flood risks remain as B.C. heat wave smashes temperature records

Environment Canada says unseasonably hot temperatures in British Columbia will persist over the coming days, with special weather statements 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,but coolingtemperatures overnight will provide people with some relief.

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

Agassiz saw temperatures of 31.6 C, topping therecordof 31.3 C set in 2018. Fort Nelson set a newrecordof 28.1 C, breaking the old one of 25.6 C set in 1973.

Temperatures at theSquamishAirport reached 32.4 C, beating the previousrecordof 29.6 C seen in 2018.

Environment Canada meteorologist LouisKohanyisaid 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.''

Along with the wildfires,the province is also grappling withflood risks in certain areas as thesnowpackmelts.

The provincial River Forecast Centre issued highstreamflowadvisories for the Dean and BellaCoolarivers warning of rapidly rising waters, but major flooding isn't expected.

The centre's highstreamflowadvisory for the Upper Columbia, WestKootenay, EastKootenay, and Boundary River also includes the Kettle River,GranbyRiver and surrounding tributaries.

"Snowmeltrates have been increasing over the past two days. In mid-elevation terrain,snowpacksare 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 dwindlingsnowpackthere is uncertainty whether flows will exceed levels previously experienced earlier in May."

At 12:30 p.m. Sunday, the forecast centre downgraded a flood warning for the Middle Fraser River to a high streamflow advisory, and issued a high streamflow advisory for the Upper Fraser River.

In the centre's three-tiered warning system, a flood watch meansriver levels are rising and flooding might occur.It is precededby a high streamflow advisorythe lowest of the three levels issued by the River Forecast Centrethat indicates minor flooding in low-lying areas is possible.

MLA calls for proactive measures

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.

B.C. United MLA for Fraser-NicolaJackie Tegart, whose riding includes Cache Creek, said Sunday that her constituency "seems to be the epicenter of any kind of climate change disaster that's going to happen.''

Tegart said the village and its residents are now dealing with the challenging aftermath of earlier flooding in addition to damage to the highway snarling traffic as people wait to return to their homes after evacuation.

She said her riding is hit with many seasonal challenges, including flooding as the spring snowmelt begins followed by droughts in the summer months, highlighting the need for proper water storage and other mitigation measures.

Other areas in her riding have been devastated in the past, Tegart said, including the fire that razed the town of Lytton in June 2021, and the atmospheric river event that flooded Merritt in November thatsame year.

As Cache Creek digs out of the most recent flooding and begins repairs on its highways that are essential to provincial commerce, Tegart said climate-related disasters highlight the "need to understand the connection between urban areas and how important the rural infrastructure is to how our province runs.''

"I think we've been living through climate change in Fraser-Nicola and what what people in my riding are saying is we'vehad enough talk, we need some action,'' Tegart said.

"We need some planning done so that we can look at what kind of experiences people have had over the last five to tenyears and how do we as a province start to be proactive.''
