It's most likely the FAA problem: the official Pilot Operating Handbook for their helicopters top out at 120F and they cannot legally operate them. As tstrimple points out in a sister comment, Death Valley (elevation below sea level) at 130F is like 5,000' ASL at 60F, well within most ambulance helicopters operating range.
