At least four deaths have been attributed to the sweltering heat that has plagued Arizona this weekend.

The Arizona Republic reported that four hikers collapsed and died on trails across the state. One hiker died in the Phoenix Mountain Preserve, another died on the Peralta Trail in the Superstition Mountains, a third near Finger Canyon Rock and a fourth in Ventana Canyon.

“It really shows how critical this heat can be and how it can really sneak up on you,” Phoenix Fire spokesman Capt. Larry Subervi told the paper. “When we deal with temperatures like this, it can just really be unpredictable how your body is going to respond.”

The blistering heat broke records across the state Sunday. Temperatures in Phoenix, Flagstaff, Tucson and Yuma broke daily records, according to the National Weather Service. Phoenix topped off at 118 degrees, Tucson at 115 degrees, Flagstaff reached 93 degrees and Yuma was scorching at 120 degrees.

According to the Arizona Republic, temperatures sharply rose Sunday morning and the records started to shatter by noon. Yuma topped the mercury off at 117 by 12:20 p.m. The daily high of 120 degrees ties the city’s fourth-highest temperature.
