Dozens of wildfires burn across torrid Western U.S. West with extreme temperatures expected to last until Tuesday evening before returning this weekend
- Wildfires are burning across more than one million acres of the western United States and Canada
- It comes as scorching temperatures held their grip on areas reeling from a brutal weekend heat wave
- 850,000 acres were ablaze in the United States in western states such as Oregon, California and Arizona
- Extreme temperatures in recent days reached as far inland as the edge of the Rocky Mountains
- US National Weather Service has warned dangerous temperatures will continue for the early part of the week
- Temperatures up to 116 degrees Fahrenheit (47 Celsius) were recorded in southern California Monday, and a heat advisory issued for communities outside Los Angeles
- NWS said overall temperatures were beginning to dip, with breezes arriving in northern California and storms in Arizona and New Mexico on Monday, but excessive heat warnings remain in effect until Tuesday
Wildfires that torched homes and forced thousands to evacuate burned across 10 parched Western states on Tuesday, and the largest, in Oregon, threatened California's power supply.
Nearly 60 wildfires tore through bone-dry timber and brush from Alaska to Wyoming, according to the National Interagency Fire Center. Arizona, Idaho and Montana accounted for more than half of the large active fires.
The fires erupted as the West was in the grip of the second bout of dangerously high temperatures in just a few weeks. A climate change-fueled megadrought also is contributing to conditions that make fires even more dangerous, scientists say.
The National Weather Service says the heat wave appeared to have peaked in many areas, and excessive-heat warnings were largely expected to expire by Tuesday. However, they continued into Tuesday night in some California deserts, and many areas were still expected to see high in the 80s and 90s.

In Northern California, a combined pair of lightning-ignited blazes dubbed the Beckwourth Complex was less than 25% surrounded after days of battling flames fueled by winds, hot weather and low humidity that sapped the moisture from vegetation. Evacuation orders were in place for more than 3,000 residents of remote northern areas and neighboring Nevada.
There were reports of burned homes, but damage was still being tallied. The blaze had consumed 140 square miles (362 square kilometers) of land, including in Plumas National Forest.
A fire that began Sunday in the Sierra Nevada south of Yosemite National Park exploded over 14 square miles (36 square kilometers) and was just 10% contained. A highway that leads to Yosemite´s southern entrance remained open.
The largest fire in the United States lay across the California border in southwestern Oregon. The Bootleg Fire - which doubled and doubled again over the weekend - threatened some 2,000 homes, state fire officials said. It had burned at least seven homes and more than 40 other buildings.

Over the weekend, the Klamath County Sheriff´s Office warned that it would cite or even arrest people who ignored orders to 'go now' in certain areas immediately threatened by the blaze.
Tim McCarley told KPTV-TV that he and his family were ordered to flee their home on Friday with flames just minutes behind them.
'They told us to get the hell out ´cause if not, you´re dead,' he said.
He described the blaze as 'like a firenado,' with flames leaping dozens of feet into the air and jumping around, catching trees 'and then just explosions, boom, boom, boom, boom.'
The fire was burning in the Fremont-Winema National Forest, near the Klamath County town of Sprague River. It had ravaged an area of about 240 square miles (621 square kilometers), or nearly twice the size of Portland.
Firefighters hadn't managed to surround any of it as they struggled to build containment lines.
The fire drastically disrupted service on three transmission lines providing up to 5,500 megawatts of electricity to California, and that state's California's power grid operator has repeatedly asked for voluntary power conservation during evening hours.

Scientists say a similar heatwave at the end of June 2021 would have been 'virtually impossible' without climate change

June 2021 was the hottest June on record in North America, according to data released by the European Union's climate monitoring service
Elsewhere, a forest fire started during lightning storms in southeast Washington grew to 86 square miles (223 square kilometers). It was 20% contained Monday.
Another fire west of Winthrop closed the scenic North Cascades Highway, the most northern route through the Cascade Range. The road provides access to North Cascades National Park and the Ross Lake National Recreation Area.
In Idaho, Gov. Brad Little mobilized the National Guard to help fight twin lightning-sparked fires that have together charred nearly 24 square miles (62 square kilometers) of dry timber in the remote, drought-stricken region.
The July heat wave follows an unusual June siege of broiling temperatures in the West, and comes amid worsening drought conditions throughout the region.
Scientists say human-caused climate change and decades of fire suppression that increases fuel loads have aggravated fire conditions across the region.
