Tucson Sector Border Patrol agents have rescued 19 people in just six days (June 21-26) because of the heat.
Border Patrol has been able to reach more people in distress because resources have shifted to the west desert area between Tucson and Yuma.
Officials continue to warn the public, both north and south of the border, that hiking through the desert is dangerous this time of year.
If anyone is in distress, for any reason, officials say to call 9-1-1 or activate a rescue beacon.
The Tucson Sector Border Patrol agents rescued more than 1,400 people in 2016, mostly in the western Arizona.
