The BBC reports extreme heat is building in the western United States, with forecasts of record-breaking temperatures in the states of California and Nevada.
It comes just weeks after another dangerous heatwave hit North America, and the region has experienced the hottest June on record.
California’s Death Valley on Friday recorded a high of 54.4C (130F), with similar heat expected this weekend.
Millions of people in the US are under warnings of excessive heat.
The National Weather Service has advised those affected to drink plenty of water and stay in air conditioned buildings.
The temperature in Death Valley on Friday matched one recorded in August 2020 – which some argue is the highest temperature ever reliably recorded on Earth. A temperature of 56.7C (134F) was recorded in 1913, but this is contested by climate experts.
