The triple digit heat in the Phoenix area will continue into mid-September.
Larry Hopper of the National Weather Service says an excessive heat warning is in place for Monday.
"High temperatures are expected in the upper 100s for Phoenix. We’re forecasting 109 degrees, so it’s important to make sure everyone stays hydrated and drinks before they’re thirsty, and also, try to complete most of your outdoor activities early in the morning," he said.
Hopper says temperatures will decrease to about 103 by the end of the week, with lows near 80.
