People in Canada and US face new scorching hot temperatures

Canada : Millions of people across the western United States and Canada had to face the new scorching hot temperatures on Sunday, forcing authorities to close some roads, allow limited train traffic and new evacuations ordered.

Meanwhile, 50 more blazes erupted in Canada in last two days. 

Sweltering conditions hit much of the Pacific seaboard and as far inland as the western edge of the Rocky Mountains over the weekend.

"A dangerous heat wave will affect much of the western US, with record-breaking temperatures likely," the National Weather service said on its website Sunday, while Canadian meteorologists predicted highs approaching 90 Fahrenheit (32 Celsius) in parts of western Canada -- well above seasonal norms.

Las Vegas on Saturday matched its all-time record of 117 degrees Fahrenheit, according to the National Weather Service (NWS) -- a temperature recorded in the desert entertainment city once in 1942 and three other times since 2005.

Death valley in California - often the nation's hottest spot - was headed for a high of 126 degrees Fahrenheit.

The forecasters have alerted for an excessive heat wave for several other urban centers including the southern city of Phoenix and San Jose, the center of the Silicon Valley tech industry south of San Francisco.

The scorching conditions saw the all-time record daily temperature broken three days in a row in the Canadian province of British Columbia.
