The sweltering heat appears to have caused at least five deaths in Oregon since Friday.
On Monday, the Multnomah County Medical Examiner’s office reported it is looking into three possible heat-related deaths of county residents.
The first suspected heat-related death was reported on Friday, when a man was found dead in the Cully neighborhood. Two more deaths were reported on Sunday: One man was found dead in the Mt. Scott area and another was found in the Hazelwood neighborhood.
Additionally, on Saturday, a man from outside of Multnomah County died from a suspected heat-related illness after he was taken to a Portland hospital. Officials confirmed Monday, the man was a resident of Clackamas County.
A fifth heat-related death was also reported over the weekend in Coos County, Oregon. According to the Oregon State Medical Examiner’s office, he was 33 years old. At this time, no additional details surrounding his death have been released.

Temperatures soaring into the triple digits has historically been rare in Oregon. But the latest heat wave is part of a warming trend tied to human-caused climate change that has been more evident in the past four years.
The National Weather Service says temperatures are expected to peak Tuesday when highs could reach 105 degrees in the Willamette and Hood River valleys.
Officials are not releasing any additional details about the four men’s deaths. They added that the causes of death are preliminary and more tests are needed to confirm.
Heat-related illnesses are among the leading causes of death related to extreme weather. In 2021, 96 people died in a heat wave extending across the state. Most of those people lived in Multnomah County.
According to officials in Benton, Clark, Clackamas, Gilliam, Linn and Washington counties, no other suspected heat-related deaths have been reported so far.
