A Phoenix heat wave of unprecedented intensity for March is set to torch the record book and produce the year's first triple-digit temperatures.
Forecasters are calling the early heat event 'unprecedented,' with temperatures as high as 25 degrees above normal in some areas.
Weather and health officials encouraged people to begin hydrating immediately and to be careful during the early phases of the heat wave. Outside workers were encouraged to find shade where they can take more rest breaks than normal.
The record for earliest 100-degree day in Phoenix has stood for 38 years, but that could change.
