A visitor to Death Valley national park died on Sunday from heat exposure and another person was hospitalized as the temperature reached 128F (53.3C) in eastern California, officials said.
The two visitors were part of a group of six motorcyclists riding through the Badwater Basin area amid scorching weather, the park said.
The person who died was not identified. The other motorcyclist was hospitalized in Las Vegas for “severe heat illness”, the statement said. The other four members of the party were treated at the scene.
“High heat like this can pose real threats to your health,” said park superintendent Mike Reynolds.
“Besides not being able to cool down while riding due to high ambient air temperatures, experiencing Death Valley by motorcycle when it is this hot is further challenged by the necessary heavy safety gear worn to reduce injuries during an accident,” Reynolds said.
The death comes as a long-running heatwave has shattered temperature records across the US, with about 36 million people – roughly 10% of the country – under excessive heat warnings, National Weather Service’s (NWS) meteorologist Bryan Jackson said.
Dozens of locations in the west and Pacific north-west were expected to tie or break previous heat records, he said.
That was certainly the case over the weekend: many areas in northern California surpassed 110F (43.3C), with the city of Redding topping out at a record 119F (48.3C). Phoenix set a new daily record on Sunday for the warmest low temperature: it never got below 92F (33.3C).
Triple-digit temperatures were common across Oregon, where several records were toppled – including in Salem, where on Sunday it hit 103F (39.4C), topping the 99F (37.2C) mark set in 1960.
Rare heat advisories were extended even into higher elevations including around Lake Tahoe, on the border of California and Nevada, with the weather service in Reno, Nevada, warning of “major heat risk impacts, even in the mountains”.
The NWS is also warning of increased wildfire risks due to a mix of hot, dry and windy conditions. In southern California, residents were ordered late on Saturday to evacuate parts of Santa Barbara county, where the Lake Fire has scorched more than 13,000 acres since Friday, according to Cal Fire.
Each of the past 12 months have ranked as the warmest on record in year-on-year comparisons across the globe, according to the Copernicus Climate Change Service, European Union’s climate change monitoring service, which links human activities like the combustion of fossil fuels to climate change-causing greenhouse gas emissions.
Last week, Joe Biden’s administration proposed the first-ever safety standard intended to protect workers and communities from the impacts of extreme heat.
