DEATH VALLEY, Calif. (AP) – Authorities in Oregon’s Multnomah County, home to Portland, reported on Monday four suspected heat-related deaths as the region continued to swelter under an early heat wave.
The county medical examiner was investigating at least three such deaths reported on Friday and Sunday, officials said, adding that a fourth man transported from outside the county died from a suspected heat-related illness at a Portland hospital on Saturday.
Authorities said it will take investigators weeks or months to confirm the causes of death.
Oregon’s most populous city broke daily record temperatures on Friday, Saturday and Sunday and was on track Monday to do so for a fourth consecutive day with a forecasted high of 102 degrees Fahrenheit (38.9 Celsius), said National Weather Service meteorologist Hannah Chandler-Cooley.
“We are looking at the potential for breaking more records,” she said.
The county has been operating three daytime cooling centers since Friday with the aim of providing relief to those more vulnerable to heat-related illness, such as people living outside, older people, people with disabilities and people whose homes don’t have air conditioning.
After causing deaths and shattering records in the West over the weekend, a long-running heat wave will again grip the U.S. on Monday, with hot temperatures also predicted for large parts of the East Coast and the South.
The dangerous temperatures caused the death of a motorcyclist in Death Valley.
The U.S. heat wave came as the global temperature in June was record warm for the 13th straight month and it marked the 12th straight month that the world was 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than pre-industrial times, the European climate service Copernicus said.
An excessive heat warning, the National Weather Service’s highest alert, was in effect Monday for portions of states including California, Nevada, Arizona, Oregon, Washington and Idaho, while parts of the East Coast as well as states including Florida, Georgia, Alabama and Mississippi were under heat advisories.
Dozens of locations in the West and Pacific Northwest tied or broke previous heat records over the weekend.
A high temperature of 128 F (53.3 C) was recorded Saturday and Sunday at Death Valley National Park in eastern California, where a visitor died Saturday from heat exposure and another person was hospitalized, 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 in a statement.
The person who died was not identified. The other motorcyclist was transported to a Las Vegas hospital for “severe heat illness,” the statement said. Due to the high temperatures, emergency medical helicopters were unable to respond, as the aircraft cannot generally fly safely over 120 F (48.8 C), officials said.
The other four members of the party were treated at the scene.
“While this is a very exciting time to experience potential world record setting temperatures in Death Valley, we encourage visitors to choose their activities carefully, avoiding prolonged periods of time outside of an air-conditioned vehicle or building when temperatures are this high,” park Superintendent Mike Reynolds said.
Caution is urged during hot weather
Officials warned that heat illness and injury are cumulative and can build over the course of a day or days.
“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,” the park statement said.
Across the desert in Nevada, Las Vegas on Sunday set a record high of 120 F (48.8 C).
Triple-digit temperatures were common across Oregon, where several records were toppled, including in Salem, where on Sunday it hit 103 F (39.4 C), topping the 99 F (37.2 C) mark set in 1960.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” read a weather service advisory for the Baltimore area. “Young children and pets should never be left unattended in vehicles under any circumstances.”
Heat records shattered across the Southwest
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.”
“How hot are we talking? Well, high temperatures across (western Nevada and northeastern California) won’t get below 100 degrees (37.8 C) until next weekend,” the service posted online. “And unfortunately, there won’t be much relief overnight either.”
More extreme highs are in the near forecast, including possibly 130 F (54.4 C) around midweek at Furnace Creek, California, in Death Valley. The hottest temperature ever officially recorded on Earth was 134 F (56.67 C) in July 1913 in Death Valley, though some experts dispute that measurement and say the real record was 130 F (54.4 C), recorded there in July 2021.
