Unusually high temps for this time of year settled in over southern Arizona Monday afternoon contributing to the second heat-related death in three days and causing the National Weather Service to issue a heat advisory through the early evening for the southwestern part of the state.

The high hit 105 degrees, making it one of the earliest days to reach 105 since the late 1800s.

Tucson doesn’t usually feel that kind of heat until June, said John Glueck, a NWS forecaster.

The heat contributed to the death of a 35-year-old German tourist hiking in Saguaro National Park West Monday afternoon.

The woman was hiking with a companion from Germany when she collapsed near the Hugh Norris Trail Head near North Hohokam and North Kinney roads shortly after 2 p.m., said Sgt. Dawn Barkman, a Pima County Sheriff’s Department spokeswoman. She was pronounced dead at the scene.

An Illinois woman celebrating her 23rd birthday died May 19 after experiencing heat-related symptoms while hiking in the Tortolita Mountains with family.

An uptick in calls for heat-related conditions and the recent fatalities has caused officials to stress the importance of knowing and recognizing the signs and symptoms of heat exhaustion and heat stroke.

“People have to listen to their bodies, everyone has a different physical capability,” said Capt. Adam Goldberg, a spokesman for Northwest Fire Department which has responded to several heat-related calls and one of the recent heat-related deaths.

Common signs of dehydration and heat exhaustion include: thirst, aches and pains, muscle cramping, feeling light headed or dizzy, nausea and vomiting, excessive sweating, cool, moist, pale or red skin.

When heat exhaustion progresses to heat stroke people will stop sweating, have labored breathing, become unresponsive or unconscious and possibly have seizure-like activity.
