An extreme heat warning for Phoenix and surrounding parts of Arizona will come into force at 10am local time on Tuesday, September 8, as temperatures are forecast to rise sharply across the lower desert.
The National Weather Service has issued the warning until 8pm on Thursday, September 10, covering central and northern Phoenix, Glendale, Scottsdale, the East Valley, the Gila River Valley, Yuma County and several desert communities.
Forecasters expect temperatures in Phoenix to reach about 107F (42C) on Monday, with highs of roughly 104F (40C) forecast in Scottsdale on Tuesday. The National Weather Service said temperatures could climb to between 5F and 10F above normal during the middle of the week.
The warning also includes areas such as Paradise Valley, Ahwatukee, Queen Creek, Cave Creek, New River, Buckeye, Avondale, Gila Bend and the Sonoran Desert National Monument.

The Phoenix weather office said the conditions would bring widespread moderate to major heat risk, with the greatest danger for people without effective cooling or adequate hydration.
Residents have been urged to drink plenty of water and electrolytes, limit time outdoors during the afternoon and avoid strenuous activity during the hottest part of the day.
The warning comes as above-normal temperatures are expected to persist across the region before a gradual cooling trend later in the week. Shower and thunderstorm chances are also expected to return in parts of Arizona during the latter half of the week.
