Tuesday, June 29th 2021, 3:58 pm - As records continue to shatter under the historic heat wave in the West, some good news is on the horizon for those on B.C.'s South Coast as the hot temperatures shift further east.
The new Canadian temperature record set on Sunday, which previously stood for about 83 years, lasted for less than 24 hours. It might only survive for another 24 hours.
Lytton, B.C., pushed to nearly 48°C (47.9°C) for the first time in Canadian history on Monday, and all-time temperatures were reached in many communities across B.C. The community broke its previous record of 46.6°C, established just a day prior.
Humidex values soared above 50 in the Fraser Valley, a first for this part of the world and spectacularly rare for Canada. Since Friday, several all-time and/or monthly highs, as well as dozens of daily records have been broken.
Now, some good news.
A little bit more of the marine air will advance into the South Coast, so think mid-30s for Vancouver Island and the Lower Mainland. Which, up until now, was a benchmark for a hot day.
But, travel up the Sea-to-Sky, or head east on the TransCanada, we're in for another day of severe, dangerous heat.
Tofino found its missing marine layer, with temperatures back to seasonal, but it's the exception across the province for Tuesday.
Note how far north into northern B.C. the heat migrates under the heat dome.
The city's previous all-time high temperature was 36.4°C, which was set on Sunday, broken on Monday, and will be surpassed on Tuesday – with a likely temperature over 40°C.
By Wednesday, a sense of normalcy returns to the temperatures in Squamish. Note the fresh, marine air that’s pushed across Victoria -- an incredible feeling after temperatures pushed to 40°C for the first time.
On Wednesday, temperatures in the Northwest Territories will tip over 40°C south of Yellowknife -- and if captured by a weather station, this will be the first time in recorded history.
Yohin Lake soared to 38.1°C on Sunday, making it the second warmest June temperature on record for the territory.
All-time records will fall across Alberta, as well, as the heat wave peaks by Wednesday for the province.

RECORD POWER DEMAND REACHED, ACCORDING TO BC HYDRO
The extreme heat should be taken seriously as it could harm your health and cause heat-related illnesses.
“Heat-related illness is the result of your body gaining heat faster than it can cool itself down,” states HealthLink BC on their website. “Those at increased risk for heat-related illness include: infants and children, people 65 years of age or older, and people who do a lot of physical activity or work in a hot environment. In most cases, heat-related illnesses are preventable.”
Heat stroke is a life-threatening medical emergency. Call 9-1-1 or other emergency medical services as soon as you suspect or see the signs of heat stroke in an individual. Click here to learn more about heat stroke.
Heat stroke shares some symptoms with heat exhaustion, but the most acute to watch out for (according to Canadian Centre for Occupational Health and Safety) are:
- Hot, dry skin or profuse sweating
- Loss of consciousness
- Very high body temperature
Heat stroke can follow on from untreated heat exhaustion, or can happen without little or no warning. To learn more about how extreme heat can impact the human body, click here.
