Phoenix could see deadliest year for heat deaths after sweltering summer

With 22 days hitting 110F or higher, suspected heat deaths in the Arizona capital topped 450

Extreme heat contributed to as many as 450 deaths in the Phoenix area this summer, in what could be the deadliest year on record for the desert city in Arizona.

The medical examiner for Maricopa county, which includes Phoenix, has so far confirmed 284 heat-related deaths, while investigations into 169 more suspected heat fatalities are ongoing. The highest number of deaths - and emergency hospital visits - coincided with the hottest days and nights.
