Heatwave in SW America: Temperatures hit 47 degrees

Western US states are baking in an extended heatwave, with temperatures threatening to break the all-time high recorded on Earth.

In Phoenix, Arizona, the mercury hit 47C (116F) on Friday, and in the desert of Death Valley, California, the thermometer approached 51C.

The heatwave is expected to last through the weekend.

Cities in the region are opening cooling centres and officials fear the heat could delay air travel.

Arizona resident Michael Fedo describes the conditions.
