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.
