Hot weather is poised to engulf much of BC, with the southern interior reaching the highest temperatures.
“A strong high-pressure ridge will bring a heatwave to British Columbia this week,” Environment Canada said Monday.
“The highest daily highs are expected Wednesday through Friday. Then a slow cooling trend is likely next weekend through early August.”
The national weather agency’s heat warning for the Okanagan, Similkameen, Fraser Canyon, Shuswap, Boundary, Kootenay and Thompson areas indicates daily highs will range between 35 and 40C, depending on the area. Early morning low temperatures are again in the 18-20°C range.

Temperatures in Greater Victoria, Howe Sound, Metro Vancouver and the Fraser Valley are expected to rise to 31C to 35C.
“The hottest time of the day will be from late afternoon to early evening. The coolest time of the day will be near sunrise,” Environment Canada said.

The protocol establishes daily highs and nighttime lows that would trigger the heat bulletins.
If a region is expected to exceed these ranges for two consecutive days, a heat alert will be triggered, while if it’s expected to last three or more days, a heat emergency will be triggered, Farnworth said.
Farnworth said the province is also coordinating with communities and funding refrigeration centers and arranging transportation to those sites for people who need it.
“The most important things to do is get a fan if you don’t have one, get portable air conditioning for your home, and make sure you know where to follow the weather information,” said Dr. David McVea, a public health physician at the BC Center for Disease Control.
