Unrelenting U.S. Southwest heatwave continues as power grids hold up
- 3 years ago
The U.S. Southwest baked under an unrelenting heatwave for a fifth day on Friday, putting power systems to the test as more records were expected to be broken before a moderating trend sets in next week.
The National Weather Service issued excessive heat warnings for five states - California, Nevada, Utah, Arizona and part of Colorado - where the heat has been extreme even for a region where temperatures often exceed 100 degrees Fahrenheit (38 degrees Celsius).
