An unrelenting heat wave is moving slightly east across the Prairie provinces today and experts predict parts of Western Canada could again reach record-breaking high temperatures.

An unrelenting heat wave is gradually movingeastacross the Prairie provinces Wednesday, and parts of western Canada could again reach record-breaking high temperatures.

Much of British Columbia and Manitoba, parts of the Northwest Territories and all of Alberta and Saskatchewan are under Environment Canada heat warnings.

To blame is what meteorologists have called a heat dome;ridges of high pressure hovering over the Prairies that create an effect much like a pressure cooker.

According to David Phillips, a senior climatologist with Environment Canada, the heat dome is "a long term kind of thing this one has legs."

He says that as the heat wavemoves eastit will become less intense andlikely won't reach the eastern provinces.

"Winnipeg would be sort of the last major city to see this heat dome," he said.

A heat wave warning is in effect in several provinces in Canada. As of Wednesday evening, the warning expanded to cover much of Manitoba, and one alert for the Bulkey Valley and the Lakes District area in central B.C. was lifted. (CBC)

Shattering record temperatures

Alberta broke 38 daily temperature records on Tuesday, according to Environment Canada, thehottest of those being 41.5 C in the Grande Prairie area, 40.7 C in the Beaverlodgearea and and 39.3C in the Drumhellerarea.

The province has had four straight days where it broke daily temperature records in whatPhillips callsa "spectacular episode."

Calgary neared its all-time high temperature record, hitting 36.3 C Tuesday. The hottest the city has ever been was 36.5 C, a record set in August 2018, according to Environment Canada.

Today's high is expected to reach 35 C in Calgary, 37 C in Edmonton and 39 C in Grande Prairie.

Most of Manitoba was under a heat warning as of Wednesday evening.

A new Canadian temperature record was set on Tuesday in the town ofLytton, B.C., which reached 49.6 C.

With the heat dome shifting east, Albertans are feeling its brunt and scrambling for fans, air conditioning and water to keep cool.

B.C. continues to see the highest temperatures in Canada with temperatures in cities like Kelowna, Vernon and Kamloopsremaining in the low 40sthough Phillips says temperatures will drop slightly.

"My sense is by this time at the end of the weekend, it will pretty wellhave passed through," he said. "The warm temperatures will linger, but not as excruciatingly."

The Northwest Territories and Yukon have broken 20 daily temperaturerecords so far. It was 38.1 C in Nahanni Butte, N.W.T., on Monday, the highest temperature ever recorded in the region.

Booking hotel roomsforAC relief

The city ofCalgary says water consumptionis higher than the city's five year average, and advisedpeople to be mindful of their water use, especially when watering lawns.

Electricity use in Alberta also surgedthis week, pushing the province past a summer usage record of 10,822 megawatts, set in 2019.

Some Calgarians are even checking into hotels to avoid the heat in their homes and take advantage of hotel pools.

According to Elena Menk, associate director of sales for the Hotel Arts in downtown Calgary, hotel visits are up.

"We've seen an increase in bookings about 40 per cent in the last seven days," she said. "People are booking just to get some ACgoing."

Steve Kerr, an Edmonton-based regional sales manager at Service Experts Heating and Air Conditioning, said this summer ishis "busiest season I can ever remember in my 20 years."

Dangers of extreme heat

In some cases, the extreme temperatures have turned deadly.In B.C., at least 486 sudden deaths were reportedover five days during the province's heat wave,the BCCoroners Service said Wednesday.

It's too early to know how many of the deaths were "heat related" Chief CoronerLisa Lapointe said Wednesday in a statement.

"It is believed likely that the significant increase in deaths reported is attributable to the extreme weather B.C. has experienced and continues to impact many parts of our province," she said.

As of late Tuesday, there were 16 heat-related visits to emergency departments in Calgary and Edmonton.
