KAMLOOPS — A heat wave is going to impact B.C. this week.

In a public alert issued Monday (July 25) morning, Environment Canada says B.C. will reach daytime high temperatures between 35 to 40 degrees Celsius and early morning lows of 18 to 20 degrees. The heat warning is expected to begin Tuesday (July 26) and last until Saturday (July 30).

According to the weather agency, the heat wave is due to a strong ridge of high pressure. The peak daytime high temperatures are expected from Wednesday to Friday, then a slow cooling trend is likely next weekend to early August.

The hottest time of the day will be late afternoon to early evening while the coolest time of the day will be near the sunrise.

While extreme heat affects everyone, Environment Canada says the risks are greater for young children, pregnant women, older adults, people with chronic illnesses, and people working or exercising outdoors. Effects of heat illness include swelling, rash, cramps, fainting, heat exhaustion, heat stroke, and the worsening of some health conditions.

The heat warning covers most of B.C., including the South Thompson, North Thompson, Nicola, Shuswap, 100 Mile, Cariboo, and Fraser Canyon regions.
