Lytton, a village in British Columbia, became the first place in Canada to record a temperature above 113 degrees Fahrenheit on Sunday, with the thermometer hitting 116 degrees.

But that national record did not last for long. On Monday, according to government weather agency Environment Canada, Lytton saw temperatures soar to just above 118 degrees on Monday.

As The Washington Post’s Capital Weather Gang noted, that is one degree higher than the record in Las Vegas, the desert city more than a thousand miles south of Lytton.

The heat could have a devastating effect on Canada’s west, where such high temperatures are unusual, and not all residents have air conditioning.

In Burnaby, neighboring Vancouver in British Columbia, local law enforcement announced Tuesday that they had responded to more than 25 “sudden death” calls in 24 hours.

Though the causes of death were still being investigated, police said that many of the victims were elderly and that the heat was suspected to be a contributing factor.

“We are seeing this weather can be deadly for vulnerable members of our community, especially the elderly and those with underlying health issues. It is imperative we check on one another during this extreme heat,” said Col. Mike Kalanj with Burnaby Royal Canadian Mounted Police.

In nearby Surrey, officials told local reporters that they, too, were seeing an unusual number of calls related to deaths.

Surrey police had responded to 22 sudden-death calls Monday and 13 by midday Tuesday, according to the Surrey Leader.

Though the causes of the deaths had not been determined, police were “responding to a higher-than-usual number of deaths since the beginning of the extreme weather conditions,” Constable Sarbjit Sangha told the local newspaper.

The previous Canadian records for hottest temperature, both 113 degrees, were set in Yellow Grass and Midale in Saskatchewan on July 5, 1937.

“It’s warmer in parts of western Canada than in Dubai. I mean, it’s just not something that seems Canadian,” Environment Canada senior climatologist David Phillips told CTV News on Saturday.

In the metropolitan hub of Vancouver, parks, beaches and pools have been flooded with residents eager to cool off as the temperature hit 89 degrees at the local airport Sunday — a record in a coastal city that usually has mild weather.

Canada’s record comes amid a severe heat wave in the Pacific Northwest, with records Monday of 116 degrees in Portland, Ore., and 108 degrees in Seattle.

The heat wave is expected to continue for several more days. CTV News reported that predictions for Tuesday suggest Lytton’s high temperatures would last until at least Tuesday.

The high temperatures in the region have been blamed on a “heat dome,” a sprawling area of high pressure, now sitting over western Canada and the Pacific Northwest. Experts say climate change can make extreme weather events like this more common.

Air conditioning is not standard in British Columbia, and Canadian outlets reported that locals were having a hard time finding air conditioners and fans over the weekend.

Environment Canada has issued heat warnings for a variety of people, including young children, pregnant women, the elderly and those with chronic illnesses.

BC Hydro, the main electric utility company in British Columbia, warned Monday that electricity demand was also setting records. “Extreme heat leads to record-breaking electricity demand for a second day in a row,” the company said on Twitter.

“This heatwave is exactly the type of extreme weather scientists told us would happen as a result of climate change,” Sonia Furstenau, leader of the Green Party of British Columbia, tweeted on Monday.

British Columbia is “now facing a reality of extreme weather events or forest fires every single summer,” Furstenau added.
