The death of a hiker at Southern California's Joshua Tree National Park over the weekend has prompted officials to warn visitors about the dangers of exposure as a heat wave grips the region.
The Los Angeles Times reports Tuesday that the 56-year-old woman died after collapsing while hiking with her husband as temperatures hovered around 100 degrees.
The death is under investigation. Park spokeswoman Jennie Albrinck tells the newspaper that the hiker showed signs of heat-related stress before she went unconscious Saturday. Her name has not been released.
More high heat and elevated fire danger is in store Tuesday for much of Southern California, especially interior areas. The National Weather Service says triple digit temperatures are expected across the warmest portions of the valleys, foothills and lower mountains.
