(CNN)Extreme heat and dry conditions are fueling raging wildfires in the western US, charring more than a million acres, requiring evacuations and creating smoky conditions visible from space.
The smoke mixed down to the surface in New York City, creating an eerie scene Wednesday morning — though a cold front is expected to usher the smoke out of the area later in the day.
In the West, the fires have caused power outages, destroyed structures and prompted the deployment of the Oregon National Guard.
As extreme drought still grips most of the West and the fires have become so intense they've created their own weather systems, the threat of more fires remains.
In Oregon — where eight fires have burned nearly 475,000 acres — officials said the current fire season is unlike any they've seen before.
“I would categorize this fire season thus far as historic in terms of the amount of resources we've deployed, how many times we've deployed — within a three-week period we've mobilized to six conflagrations — and this is the earliest and most significant mobilization to date,” Mariana Ruiz-Temple with the Oregon fire marshal's office said Tuesday.
At least 1.29 million acres have burned in 83 large fires across 13 states as of Tuesday, according to the National Interagency Fire Center. More than 19,000 wildland firefighters and support personnel have been deployed to deal with the blazes.
Advisories for elevated fire potential and activity have been issued across Idaho, California, Oregon and the Northern Rockies, according to fire center.
It's not just fires in the US contributing to the smoky haze. The Canadian province of British Columbia declared an emergency due to wildfires there effective Wednesday. Nearly 300 active wildfires have been reported in the province.
Bootleg Fire is largest in country
In Oregon, record-breaking, triple-digit temperatures and severe drought have devastated parts of the state.
The conditions are fueling the Bootleg Fire in southern Oregon, which is the largest burning wildfire in the country. The Bootleg Fire has scorched more than 394,000 acres and prompted evacuations with only 32% containment, according to InciWeb, the US clearinghouse for wildfire information.
The climate crisis has made deadlier and more destructive wildfires the new normal. And Oregon Gov. Kate Brown cited recent fires, ice storms, record-breaking high temperatures and drought emergencies as evidence that climate change is impacting her state.
“There's absolutely no question that climate change is playing out for before our eyes,” Brown said at a news conference Tuesday. “We saw the heat dome event a few weeks ago; we unfortunately lost a lot of Oregonians through that event. In February, we saw devastating ice storms, over a half a million people lost power last fall, as you are well aware; we've had unprecedented wildfires.”
Fire potential in the state is being driven by drought conditions, with 90% of the Oregon in either exceptional, extreme or severe drought, Doug Grafe, chief of fire protection at the Oregon Department of Forestry said while forecasting a “long, difficult fire season.”
He said it's possible that another 50,000 to 100,000 acres could burn before the Bootleg Fire is contained.
“The future for us for the remainder of the season continues to look above normal dry and above normal temperatures,” Grafe said. “So this is not going to return to normal anytime soon.”
Red flag warnings in the area will continue into Wednesday evening, signaling dry and windy conditions with lots of smoke, CNN meteorologist Michael Guy said.
As a result of the fires, 62 members of the Oregon National Guard have been deployed, along with Blackhawk helicopters to provide water drops, fire spotting and medivac support, Major General Michael E. Stencel, Adjutant General of the Oregon National Guard said.
In addition to feeding fires, Oregon's hot, dry conditions are also impacting Christmas trees grown in the state.
“It's killing them,” Jacob Hemphill, a Christmas tree farmer in Clackamas County, said of the relentless heat this summer. “It's horrible, there is nothing we can do.”
Unusually warm temperatures and severe dryness this year have caused irreversible burns on many trees, resulting in fewer trees to choose from this upcoming holiday season as well as potentially higher prices, growers said.
California's Dixie Fire may have been sparked by electrical equipment
Butte County is the site of California's deadliest and most destructive wildfire in 2018, the Camp Fire. It burned a total of 153,336 acres, destroyed 18,804 structures, and killed 85 people.
The Dixie Fire is so intense, it produced a thunderstorm, Incident Meteorologist Julia Ruthford said in a briefing Monday night. “The fire actually generated a thunderstorm over itself that led to some lightning out ahead of it and some really gusty and erratic winds due to that extreme, extreme conditions due to the thunderstorm overhead,” she said.
Evacuations have been ordered in the area and the fire already destroyed two structures and threatens more than 800 others.
On Tuesday, Pacific Gas and Electric said the fire may have been sparked by equipment it manages.
In a preliminary filing with the California Public Utilities Commission, PG&E detailed an outage alert July 13, the same day the fire started. A responding utility worker found three blown fuses and a tree leaning into a pole, with a small fire on the ground near the base of the tree.
The fire was reported to authorities and California Fire and Protection sent aerial firefighters to douse the flames, which had jumped from an initial estimate of 1 to 2 acres, to 10 to 15 acres, according to the filing.
Since then, the fire has grown exponentially, burning in “remote areas with limited access and steep terrain,” Cal Fire said, which is hampering access by ground crews.
Near the California-Nevada border, the Tamarack Fire, has grown to nearly 39,045 after sparking July 4, according to information from InciWeb.
A lightning strike near the Alpine County, California, community of Markleeville started the fire, which has triggered mandatory evacuations for a number of campgrounds and neighborhoods in the area, and prompted road closures.
CNN's Chris Boyette, Jason Hanna, Brisa Colon, Cheri Mossburg, Melissa Alonso, Andy Rose, and Kendall Lanier contributed to this report.
Wildfires prompt evacuations along the West Coast and hazy … Wed, 21 Jul 2021 06:00:00 -0700-Smoke from 80 wildfires in the west caused hazy skies as air quality index surged to 157 in Manhattan, above threshold of 100.
New York City air quality was among the worst in the world as cities across the eastern US were shrouded in smoke from wildfires raging several thousand miles away on the country’s west coast.
State officials in New York advised vulnerable people, such as those with asthma and heart disease, to avoid strenuous outdoor activity as air pollution soared to eclipse Lima in Peru and Kolkata in India to be ranked as the worst in the world on Tuesday.
Smoke from more than 80 major wildfires burning in the US west has caused hazy skies and plunging air quality in eastern American and Canadian cities including Philadelphia, Washington DC, Pittsburgh and Toronto, as well as New York, causing fiery sunrises and even bathing the moon in an unusual red tinge on Tuesday night.
On Wednesday morning, the air quality index surged to 157 in Manhattan, well above the threshold of 100 where health is considered to be threatened. Vulnerable people include pregnant women and the elderly, although even healthy people outside these groups can experience breathing difficulty, throat irritation and runny eyes when exposed to air this bad.
“I think it’s unusual to have this kind of haze, I don’t recall seeing this kind of thing,” said George Pope, professor of earth and environmental studies at Montclair State University, who added that he could not see Manhattan from his New Jersey office. “You can pretty much always see the skyline, at least a silhouette, if it’s a hazy day. This is, like, this is unprecedented.”
Satellite imagery shows that the smoke from the western fires has billowed into Canada and unfurled to the east, plunging states such as Minnesota into unhealthy air conditions. Winds are able to easily carry tiny sooty particles emitted from burning trees and vegetation, known as PM2.5, large distances. These PM2.5 particles can, when inhaled, burrow into the lungs and cause a variety of health problems.
“We’re seeing lots of fires producing a tremendous amount of smoke,” said David Lawrence, a meteorologist with the National Weather Service. “By the time that smoke gets to the eastern portion of the country where it’s usually thinned out, there’s just so much smoke in the atmosphere from all these fires that it’s still pretty thick.”
This is the second year in a row that smoke from huge wildfires in the US west has traveled 2,000 miles east, with the western states baked by ongoing drought and soaring temperatures fueled by human-caused climate change.
The smoke is set to shift away from New York in the coming days but further widespread wildfires are expected in the coming months, with people in the US west hit worst by the smoke as well as the direct threat of the flames.
David Turnbull, an activist at the US Climate Action Network who lives in Portland, Oregon, tweeted that people on the eastern seaboard should take care in the unhealthy air but also “take care of how you talk about the hazy skies. Your wonderment about it is our dread here in the west. Your curiosity is our constant fear. We live every day for months fearing the winds will shift, the fires will rage, and the smoke will come.”
