Southern Arizona could see record high temperatures again.
The National Weather Service says if Phoenix hits 114 degrees on Sunday, it will mark the third day in a row, setting record high temperatures in Arizona’s Urban Heart.
Much of Southern Arizona, from Phoenix to Nogales, is under an excessive heat warning.
Other western and southwestern U.S. states are experiencing above-normal temperatures in the triple-digits.
Officials are warning residents to stay hydrated and avoid the outdoors between 10 a.m. and 4 p.m., when temperatures are highest.
The Arizona Department of Health also says that neither people nor pets should be left in cars. It takes only 10 minutes for a car to reach deadly temperatures.
