Days into a heat wave forecast to stretch into next week with record-high temperatures, Environment Canada has issued a heat warning for the Kamloops region.
The heat warning comes as temperatures in the low 30s are set to rise to as high as 40 C by the weekend.
Environment Canada said “a dangerous, long duration heat wave” will affect B.C. beginning on Saturday and lasting until Tuesday.
The heat wave will bring daytime highs ranging from 35 to 40 C, combined with overnight lows of 20 to 22 C.
Along with Kamloops, the heat warning extends to the Fraser Valley, Okanagan Valley, Similkameen, Fraser Canyon, Nicola, South Thompson, Shuswap, Boundary and West Kootenay. Environment Canada said an exceptionally strong ridge of high pressure will develop over British Columbia, likely resulting in record breaking temperatures.
The forecast high of 40 C in Kamloops this weekend will nudge the all-time high of 41.7 C, recorded on on July 27, 1939, and July 16, 1941.
The weather agency said the duration of the heat wave is concerning as there is little relief at night, with elevated overnight temperatures. Environment Canada said the record-breaking heat event will increase the potential for heat-related illnesses and increase the risk of wildfires due to drought conditions.
Remember this during the heat wave
