The National Weather Service has issued an excessive heat warning for much of the West through Monday evening, predicting "dangerously hot conditions" including temperatures up to 130 degrees Fahrenheit (54 degrees Celsius) in Death Valley, California.

Temperatures are expected to soar above 100 degrees F (40 degrees C) in multiple states.

"Long standing record high temperature values are likely to be rivaled or broken," the weather service said, warning of the elevated risk of heat-related illnesses.

The extended heatwave, which coincides with a record-setting drought, has already killed at least 116 people in Oregon alone, the state medical examiner said.
