Highlights
- More than 500 possible heat-related deaths are under investigation in Maricopa County, already exceeding last year's full confirmed total.
- A woman was airlifted from Echo Canyon trailhead after her core body temperature exceeded 104 degrees.
- Maricopa County recorded its first heat warnings in March this year, the earliest ever, and has logged 36 so far versus 31 at this point last year.
- All heat-death figures remain preliminary; the county says investigations can take months to confirm.
More than 500 possible heat-related deaths are under investigation in Maricopa County this summer, a figure that already surpasses the total number of heat-related deaths confirmed in all of last year, Arizona's Family reported Monday.
The toll is playing out in real time on the Valley's trails. Over the weekend, Phoenix Fire responded to heat calls on Camelback Mountain, Piestewa Peak, and at the Echo Canyon trailhead, where a woman was airlifted after suffering heat stroke with a core body temperature above 104 degrees. Phoenix Fire Captain Mike Johnson said crews field heat-related illness calls continuously throughout the day and respond to mountain rescues on the same cadence.
"Not only are we seeing longer stretches of 100-plus degree weather, we're seeing it early, we might be seeing it later, but we're also seeing those overnight lows rising," Johnson said.
Emergency rooms are absorbing the overflow. Dr. Patrick Godwin of Banner Health said the past three weeks have been extremely busy with heat-related illness, with patients presenting with heat exhaustion, heat stroke, and in some cases organ failure.
The surge tracks with a shift in the region's heat season. Arizona's Family meteorologist Royal Norman said the county issued its first heat warnings in March this year, the earliest on record, and has logged 36 heat warnings so far compared with 31 at the same point last year. All heat-death figures remain preliminary; the county says cases under investigation can take months to be confirmed, according to the report.
The Maricopa County heat surveillance dashboard and reporting from KJZZ and KTAR independently corroborate the investigation count. Another excessive heat warning is ahead for the region.
