The record-breaking heat that has broiled the Southwest since Friday shows no signs of letting up. According to the National Weather Service, "triple-digit temperatures will be common across the Southwest" through at least Wednesday.
The temperature in Death Valley — where the temperature reached 134 degrees in 1913, the hottest temperature ever recorded on Earth — hit 128 degrees Sunday. That mark set a record high for the month of June in the U.S. The weather service says to expect similar heat today.
In what is being called the deadliest U.S. wildfire in at least 30 years, an out-of-control blaze trapped and killed 19 firefighters Sunday in central Arizona. They had been forced to use temporary shelters in an attempt to survive.
All of those killed were part of the Granite Mountain Hotshots, an elite group based in Prescott, Ariz., that uses rigorous training to prepare for fighting wildfires. They are frequently deployed to the front lines of firefighting efforts against such blazes.
