The historic heatwave continues out West with more records being broken. Today temperatures in parts of Oregon have hit 114 degrees.

To put that in perspective, the National Weather Service in the area put a thermometer in a car, to show just how dangerous these temperatures can be.

The Oregonian reports:

The heat wave began Friday, when a ridge of high pressure moved over the Pacific Northwest. With high pressure in the atmosphere, air is forced down, compressing it and warming it in a phenomenon known as subsidence. That warm air is then trapped in place by the high pressure in what is known, somewhat forbiddingly, as a heat dome.

The intense heat has been blanketing several Western states over the last couple of weeks. It even stretched into Canada where temperatures in one town in British Columbia reached 116 degrees on Sunday.

According to The Washington Post, “The strength of the heat dome, or sprawling zone of high pressure centered near the U.S.-Canada border, promoting these temperatures is setting records and off the charts. Its intensity is so statistically rare that it might be expected only once every several thousand years on average. But human-made climate change has made exceptional events such as this many times more probable.”

Since many of the cities impacted are generally mild, a lot of people don’t have air conditioning. NPR writes:

Rescue crews in several cities are dealing with a lot of medical emergencies related to the heat. Watch more from the NBC affiliate in Portland above.

Meanwhile, the Northeast is also dealing with hot temperatures and excessive heat warnings.
