A 'heat dome' that has baked the Pacific Northwest set fresh temperature records Monday as Salem in Oregon hit 117F, Portland experienced 115F heat and Canada recorded its hottest ever temperature - 117F.
Lytton in British Columbia shattered that record in Canada - just a day after the same village set the previous record of 116F.
Seattle also endured searing weather, and saw 108F weather. That comfortably eclipsed the previous 104F record just a day before, with the Washington city getting so hot that its roadways began to buckle under the heat.
Temperatures have grown so unbearable in some west coast cities that schools and COVID-19 vaccinations clinics have shut down and an Olympics qualifying event had to be postponed in Eugene, Oregon. Residents have been flocking to cooling stations set up in cities like Portland and air conditioning units and ice have been flying off the shelves across the Pacific Northwest.
Fireworks have also been banned across multiple Oregon counties ahead of the July 4 weekend, amid fears they could trigger devastating wildfires.
The historically scorching temperatures are the result of a high-pressure jet stream known as a 'heat dome,' which is essentially trapping the hot weather in place. According to CBS News, the 'heat dome' phenomenon is such a rare occurrence that it may only happen once in 1,000 years. And it comes less than two weeks after another historic heat wave wreaked havoc on the U.S. Intermountain West, Desert Southwest and California with hundreds of record highs.
'It's a desert heat – very dry and hot,' David Phillips, a senior climatologist for Environment Canada, told AFP. The 'heat dome' poses lethal health concerns, Phillips said, adding that the last major heat wave in Canada left nearly 70 people dead in 2018.
'And it's not just a one-day wonder. It's a seven-day kind of thing,' he said. 'We are the second coldest country in the world and the snowiest. We often see cold snaps and blizzards but not often do we talk about hot weather like this. Dubai would be cooler than what we're seeing now.'
Temperatures will begin to cool across much of the Pacific North West from Tuesday, to cooler 80F and 90F weather. That is still well above the 60F-70F temperatures the famously wet and lush region is used to seeing at this time of year.

Salem and Portland reached 117F and 115F, respectively, on Monday, according to the US National Weather Service, breaking Oregon's hottest recorded temperature of all time, which was 115F in Medford, 1946.

In Seattle, Washington state's largest city, the mercury climbed on Sunday to an all-time high of 104 degrees F, surpassing a 2009 record of 103 degrees.
The state capital of Olympia likewise set a new benchmark high of 105 degrees, exceeding its 2009 record by 1 degree, according to the Weather Service.
The heat wave was expected to ease somewhat west of the Cascade range by Tuesday but persist through the week to the east of those mountains, it added.
Canada braced Monday for its highest ever temperature as the country's west and swathes of the United States baked in an unprecedented heat wave, forcing schools and COVID-19 vaccination clinics to close and the postponement of an Olympic athletics qualifying event.
Temperatures have soared well above seasonal averages from the US state of Oregon to Canada's Arctic territories, with forecasters warning of worse to come.

Environment Canada issued alerts for British Columbia, Alberta, and parts of Saskatchewan, Manitoba, Yukon and the Northwest Territories, saying the 'prolonged, dangerous and historic heat wave will persist through this week.'
Because of climate change, record-setting temperatures are becoming more frequent. Globally, the decade to 2019 was the hottest recorded, and the five hottest years have all occurred within the last five years.
Although Nick Bond, an atmospheric scientist at the University of Washington, said that the freak weather event was not entirely due to climate change, only exacerbated by it.
'Climate change is a factor here, but definitely a secondary one,' he said.
