California battles wildfire as blazing heat hits western US

The ‘record-breaking heat’ is expected to affect much of the west and southwest US over the weekend, the weather centre warns.

Firefighters battled a surging wildfire in Northern California under blazing temperatures as another heatwave hits the western United States this weekend, prompting an excessive heat warning for inland and desert areas.

California’s Death Valley National Park, about 177km (110 miles) west of Las Vegas in the neighbouring state of Nevada, registered a high of 54 degrees Celsius (130 degrees Fahrenheit) on Friday and was expected to reach the same temperature on Saturday.

If verified, the temperature reading would be the highest recorded there since July 1913, when the same Furnace Creek desert area hit 57C (134F), considered the highest reliably measured temperature on earth.

The Beckwourth Complex – two lightning-caused fires burning 72km (45 miles) north of Lake Tahoe – showed no sign of slowing its rush northeast from the Sierra Nevada forest region after doubling in size between Friday and Saturday.

Local newspaper The Mercury News reported that about 1,300 personnel were deployed on Saturday to stop the flames from reaching populated areas near the blaze, while some evacuations had been ordered.

The National Weather Service (NWS) Weather Prediction Center said on Twitter on Friday morning that “record-breaking heat” was expected to affect “much of the West and Southwest” during the weekend.

“Over 31 million people are currently under an Excessive Heat Warning or Heat Advisory. Highs well into the triple digits could threaten Las Vegas’ all-time high temperature record of 117F,” the centre said.

California’s northern mountain areas have already seen several large fires that have destroyed more than a dozen homes.

Although there are no confirmed reports of building damage, the fire prompted evacuation orders or warnings for roughly 2,800 people along with the closure of nearly 518 square kilometres (200sq miles) of Plumas National Forest.

The blazes come just weeks after the northwestern US and Canada’s west coast were hit by record temperatures late last month, prompting authorities in both countries to open cooling centres and urge residents to stay cool indoors.

The heatwave contributed to hundreds of deaths in the province of British Columbia alone, officials said.

Experts have said climate change is driving more extreme weather events, such as wildfires and heatwaves – and some have urged US President Joe Biden to take up an ambitious, long-term strategy to reduce the risk of devastating wildfires.

The weekend’s potentially record temperatures on the US west coast come after the hottest June in 127 years of record-keeping, according to the National Oceanic and Atmosphere Administration (NOAA).

Eight states recorded their hottest June on record this year, while another six logged their second-hottest, the NOAA said.

Back in California, on Friday, hot rising air formed a gigantic, smoky pyrocumulus cloud that reached thousands of feet high and created its own lightning, fire information officer Lisa Cox said.

Spot fires caused by embers leapt up to 1.6km ahead of the northeastern flank – too far for firefighters to safely battle – and winds funnelled the fire up draws and canyons full of dry fuel, where “it can actually pick up speed”, Cox said.

Firefighters usually take advantage of cooler, more humid nights to advance on a fire, Cox said, but the heat and low humidity never let up.

The air was so dry that some of the water dropped by aircraft evaporated before reaching the ground, she added. “We’re expecting more of the same the day after and the day after and the day after,” Cox said.

The NWS’s Weather Prediction Center also said on Saturday that even if the temperatures do not break records, “the widespread, oppressive, and long-lasting heat remains a threat”.
