Trapped hiker suffering in 108-degree heat rescued from cliffside by chopper in Palm Springs

Southern California, Arizona and Nevada are getting blasted by another potentially deadly heat wave, with temperatures in the triple digits.

First responders in Palm Springs, California, where the desert heat is an extreme threat, have seen an uptick in distress calls coming from people who should not be outside. When lead national correspondent David Begnaud was in Palm Springs on Thursday, the temperature just after 1 p.m. was 108 degrees. And that was when the call came in to 911, of a hiker in distress, trapped on the side of a cliff and unprepared to deal with the dangerous conditions. "I'm not injured, I've just been in the sun, just sunburned," the caller said.
