San Francisco: Firefighters struggled to contain an exploding Northern California wildfire under blazing temperatures as another heatwave blanketed the West, prompting an excessive heat warning for inland and desert areas.
Death Valley in southeastern California’s Mojave Desert reached 53 Celsius on Saturday, according to the National Weather Service’s reading at Furnace Creek. The shockingly high temperature was actually lower than the previous day, when the location reached 54C.
If confirmed as accurate, the reading would be the hottest high recorded there since July 1913, when Furnace Creek desert hit 57C, considered the highest measured temperature on Earth.
About 483 kilometers northwest of the sizzling desert, the largest wildfire of the year in California was raging along the border with Nevada. The Beckwourth Complex Fire - a combination of two lightning-caused fires burning 72 kilometers 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.
Late Saturday, flames jumped Interstate 395 and was threatening properties in Nevada’s Washoe County. “Take immediate steps to protect large animals and livestock,” the The Truckee Meadows Fire Protection District tweeted.
The blaze, which was only 8% contained, increased dramatically to 222 square kilometres as firefighters sweltered in high temperatures.
It was one of several threatening homes across Western states that were expected to see triple-digit heat through the weekend as a high-pressure zone blankets the region.
Pushed by strong winds, a wildfire in southern Oregon doubled in size to 311 square kilometers Saturday as it raced through heavy timber in the Fremont-Winema National Forest near the Klamath County town of Sprague River. The National Weather Service warned the dangerous conditions could cause heat-related illnesses, while California’s power grid operator issued a statewide Flex Alert from 4 pm to 9pm Saturday to avoid disruptions and rolling blackouts.
The California Independent System Operator warned of potential power shortage, not only because of mounting heat, but because a wildfire in southern Oregon was threatening transmission lines that carry imported power to California.
Gov. Gavin Newsom issued an emergency proclamation on Friday suspending rules to allow for more power capacity, and the ISO requested emergency assistance from other states. On Saturday, Newsom issued another proclamation allowing the emergency use of auxiliary ship engines to relieve pressure on the electric grid.
Palm Springs in Southern California hit a record high temperature of 120 F (49 C) Saturday. It was the fourth time temperatures have reached 49C so far this year, the Desert Sun reported.
In California’s agricultural Central Valley, high temperatures blanketed the region, with Fresno reaching 44C, just one degree short of the all-time high for the date,
Las Vegas late Saturday afternoon tied the all-time record high of 47C, the National Weather Service said. The city has recorded that record-high temperature four other times, most recently in June 2017.
NV Energy, Nevada’s largest power provider, also urged customers to conserve electricity Saturday and Sunday evenings because of the heat wave and wildfires affecting transmission lines throughout the region.
In Southern California, a brush fire sparked by a burning big rig in eastern San Diego County forced evacuations of two Native American reservations Saturday.
In north-central Arizona, Yavapai County on Saturday lifted an evacuation warning for Black Canyon City, an unincorporated town 66 kilometers north of Phoenix, after a fire in nearby mountains no longer posed a threat. In Mohave County, Arizona, two firefighters died Saturday after a aircraft they were in to respond to a small wildfire crashed, local media reported.
A wildfire in southeast Washington grew to almost 155 square kilometers as it blackened grass and timber while it moved into the Umatilla National Forest.
In Idaho, Gov. Brad Little declared a wildfire emergency Friday and mobilized the state’s National Guard to help fight fires sparked after lightning storms swept across the drought-stricken region.
