As both countries prepare for record-breaking temperature in United States and Canada this week, a “heat dome” has developed over these countries, raising heatwave warning. With a heat of 46.6 degrees Celsius (116 degrees Fahrenheit), hotspot Lytton in British Columbia, roughly 250 kilometres (155 miles) northeast of Vancouver, set the record “for Canada’s all-time peak high,” according to Environment Canada.
Over the weekend, more than 40 new thermometer highs were recorded around the province, including in Whistler, a ski resort town. Throughout the week, the high-pressure ridge keeping hot air in the area is likely to set further records.
British Columbia, Alberta, and sections of Saskatchewan, Yukon, and the Northwest Territories were all issued alerts by Environment Canada. A lengthy, hazardous, and historic heatwave will persist this week, it stated, predicting temperatures near 40 degrees Celsius (104 degrees Fahrenheit) in numerous locations, which is 10-15 degrees Celsius above average.
The National Weather Service in the United States released a similar warning about a “harmful heat wave” temperature in United States that could see record high temperatures of more than 30 degrees Fahrenheit above average in regions of Washington and Oregon.
The historic Northwest heat is expected to last for much of the next week, with several daily, monthly, and even all-time records likely to be set, the National Weather Service stated in a report. Monday is projected to be the hottest day of the year in major cities like Seattle and Portland, with all-time highs anticipated in both.
In two villages in southeastern Saskatchewan in July 1937, the maximum temperature ever recorded in Canada was 45 degrees Celsius. Wildfire dangers are on the rise, while lake and river levels are dropping. Portable air conditioners and fans were allegedly sold out in stores, while communities erected emergency cooling facilities and outreach workers took to the streets to pass out water bottles and hats.
A number of coronavirus vaccination clinics have been cancelled, and schools have declared that they will be closed on Monday. Meanwhile, the British Columbia power utility claimed that while inhabitants struggled to stay cool, electrical consumption climbed to record highs.
