MONTREAL – Sweltering summer weather blanketed much of Canada on Monday, prompting Environment Canada to issue heat warnings for parts of eight provinces and the Northwest Territories.
In British Columbia, a record-breaking heat wave is expected to persist into midweek, with temperatures in the province’s southern Interior forecast to reach the low 40s. The weather agency attributes these scorching temperatures to a ridge of high pressure, with heat warnings covering much of southern B.C., including Metro Vancouver. On Sunday, over 20 daily heat records were shattered. The heat extends east into the Prairies, where some parts of Alberta are expected to see temperatures around 35 C by Wednesday. Heat warnings were in effect Monday across most of Alberta and into Saskatchewan, where Regina is forecast to experience daily highs around 30 C throughout the week.
In the tiny community of Fort Liard, located in the southwestern corner of the Northwest Territories, temperatures are expected to reach 30 C until Wednesday, well above its average high of 23 C.
Environment Canada is set to provide an update on the Western Canada heat wave on Monday afternoon.
In Atlantic Canada, daytime highs around 30 C are forecast, with humidex readings close to 40 in New Brunswick and Nova Scotia.
Meanwhile, the European climate service Copernicus reports that global temperatures in June hit a record high for the 13th consecutive month. The agency noted that June was the 12th straight month with global temperatures 1.5 C above the pre-industrial average, a benchmark most countries aim to limit global warming to as part of the 2015 Paris climate agreement. Eastern Canada, which experienced an intense heat wave in mid-June, was one of the regions with temperatures significantly above average.
June also marked the 15th consecutive month of record-high sea surface temperatures, according to Copernicus. A strong El Niño weather pattern has contributed to the recent spike in global temperatures, as noted by the United Nations weather agency. However, the World Meteorological Organization warned last month that the last nine years have been the warmest on record, despite the cooling influence of a multi-year La Niña event.
“The end of El Niño does not mean a pause in long-term climate change as our planet will continue to warm due to heat-trapping greenhouse gases,” said WMO deputy secretary-general Ko Barrett in a June statement.
Later this week, remnants of Hurricane Beryl, which wreaked havoc in parts of the Caribbean last week, are forecast to move into Ontario and Quebec, bringing rain and the risk of thunderstorms.
