FOX 10 Phoenix Anchor Ty Brennan talks to FOX Weather about the deadly heat baking Arizona with record-breaking high temperatures, even for July.
Unrelenting triple-digit temperatures across the West have claimed more than two dozen lives this past week in Arizona, California and Oregon, according to local medical examiners.
A heat dome has sent temperatures skyrocketing since the Fourth of July weekend. It has been hot enough to prevent emergency helicopters from flying in Southern California and bake cookies in Las Vegas.
After multiple days of record-breaking temperatures since July 5, the heat wave peaked on Monday and Tuesday in Oregon and Idaho.
The Oregon State Medical Examiner’s Office said it’s investigating 10 “potentially heat-related deaths” since the beginning of the heat advisory that started July 5.

“Oregon State Medical Examiner’s Office has received reports of 10 potentially heat-related deaths since the beginning of the current heat advisory. At this time, none of the deaths can be confirmed as heat-related. This designation as a heat-related death is preliminary and further investigation may reveal a cause of death that’s unrelated to hyperthermia. The final determination of the cause of death may not be known for several months after the death.”
The victims range in age from 27 to 87 years old and include eight men and two women.
On Tuesday, temperatures in Washington, Oregon and Idaho topped out in the low 100s, breaking decades-old records.
Portland hit 104 degrees, breaking the 1986 record of 96 degrees. Eugene and Salem, Oregon, reached a sweltering 106 degrees, breaking records set in 1926. Boise recorded a record daily high of 108 degrees on Tuesday, just 3 degrees short of the all-time record since record-keeping started in 1875.

Deadly heat has not only occurred in the West. The Maryland Department of Health reported the state’s first heat-related death of the year on June 5. Since June, five more deaths have occurred, with four happening in Prince George’s County.
Heat remains the No. 1 weather-related killer in the U.S., claiming an average of 183 lives in the U.S. each year based on the most data from 1994 to 2023.
A recent report in the journal Lancet stated that heat-related deaths worldwide are projected to jump by 370% for people over 65 by mid-century and by 1,537% by the next century.
