Extreme heat has been set in the United States and Canada, with record high temperatures forecast in California and Nevada, according to the BBC.
The warm weather came after another deadly heat hit on both sides, and the last month was recognized as the hottest June in North America in the history of meteorological measurements.
54.4 degrees Celsius was recorded in Death Valley in California on Friday, and high temperatures are expected over the weekend, BNR reports.
Millions of Americans have been warned of excessive heat.
The National Weather Service advised everyone to drink plenty of water and stay in air-conditioned buildings.
The temperature recorded on Friday in Death Valley coincides with the record of August 2020, which, according to some, is the highest recorded temperature on Earth.
In 1913, 56.7 degrees Celsius was recorded, but climatologists deny this.
Forecasters also predict that the Las Vegas record of 47.2 degrees Celsius may also be exceeded.
Canada is also preparing for severe heat, but temperatures are not expected to approach until the end of June, when the village of Lytton in British Columbia set an absolute record of 49.6 degrees.
Many deaths due to high temperatures were reported at the time.
