Wildfires are the real danger in US heat wave
The western US states are baking under an extended heat wave, with temperatures threatening to break the all-time high recorded on Earth.
Phoenix, Arizona, could see the mercury hit 48C (118F) on Friday, officials said. Temperatures higher than 37C were expected as far north as Utah.
The heat wave is expected to last through the weekend.
