Hot, dry and windy conditions are fueling a fast-moving wildfire in Utah, forcing the governor to declare an emergency and restrict fireworks as the weather across the West gives rise to mounting concerns that any spark could easily ignite a large fire.
Firefighters are facing more challenges on the ground from what fire managers and experts call unprecedented conditions.
Air tankers and helicopters were grounded Friday as winds picked up at the Cottonwood fire, which is now the largest in the country. Gusts were clocked at 45 mph and humidity levels were in the single digits, leaving crews with few options for slowing the flames, especially as they raced through the treetops.
“We are not expecting the weather to be kind to us for the next couple of days,” said Alyssa Mason, a spokesperson assigned to the fire. “We are seeing extreme fire behavior out there with some crown runs and definitely some spotting.”
Burning in a sparsely populated area of southern Utah, the Cottonwood fire ballooned Friday to more than 112 square miles. One of several large wildfires burning in Utah, it severely damaged the Eagle Point ski resort in Beaver County and forced evacuations. In the community of Marysvale, the smoke blocked out the sun Friday as ash rained down.
“We’re looking at a full 48 hours of critical weather that we have not seen in Utah in the last five years,” meteorologist Jason Straub said at a community meeting in Beaver County on Friday evening.
A cold front on Sunday will bring winds that could push the fire in new directions before the weather starts stabilizing next week, he said.
The smoke pushed mostly east, meaning air quality at popular vacation spots like Zion and Bryce Canyon national parks — far south of the flames — hasn’t been significantly affected beyond some haze in the Bryce area.
Still, the plume was visible from miles away, even as far as Colorado.
It’s like nothing seen in recent memory, Utah state forester Jamie Barnes said earlier this week. She acknowledged that fires are spreading farther and faster “under conditions that defy historical expectations.”
Nationally, nearly 3 million acres have burned since the start of the year, pushing the U.S. ahead of the 10-year average. The National Interagency Fire Center said firefighters are making progress on containing fires from Alaska to Florida.
Red flag warnings cover the West
Conditions including low humidity and strong winds have triggered red flag warnings across a wide swath stretching from Idaho to southern Arizona and New Mexico. Some of the forecasts predicted winds of 25 to 35 mph, with the worst conditions expected from northern Arizona into central and southern Utah.
At Grand Canyon National Park in Arizona, officials were preparing for a power outage on Saturday. The utility that serves the area had warned that it would probably initiate a safety outage in hopes of lessening the risk of wildfire in the area.
Visitors will be able to purchase park passes at entrance stations as long as backup power systems remain operational, but park officials said visitors should come prepared. That means downloading maps and other important information before arriving and ensuring that phones and other electronic devices are fully charged.
Power shutoffs have become more common in the West as wildfire risk has expanded. It’s usually a last resort after utility forecasters weigh factors such as sustained wind and gust speeds, available fuels and topography.
With extreme fire conditions persisting, Rocky Mountain Power has issued a public safety power shutoff watch and warning for areas of central, southern and eastern Utah through the weekend.
Persistent drought
Tim Brown, a research professor and director of the Western Regional Climate Center, said the potential for extreme fire behavior will remain as long as it’s hot, dry and windy. He pointed to parts of the West that have been mired by persistent drought, including Utah, Colorado, Arizona and New Mexico.
“I would not be surprised to see a lot of restrictions come out as we get closer to the July 4th weekend,” he said. “People really need to be aware of their surroundings if they’re going to be out in the forested campground areas and grassland areas.”
Utah Gov. Spencer Cox set the temporary fireworks restrictions through July 5 as the nation prepares to celebrate its 250th anniversary, saying that “this year is different.”
While the Cottonwood fire’s cause was unknown, the governor’s order noted that humans have been the cause of most fires in the state so far this year.
In Florida, where there have been multiple brush fires, authorities are urging people to skip the personal fireworks and instead leave the pyrotechnics to professionals putting on carefully planned shows.
Back at fire camp, Mason talked about Utah’s snowpack and stream flows peaking early in March, resulting in what she called extreme dryness. Then came the wind storms like never seen before, she said.
“If anything happens out there, any kind of spark hits fuels,” she said, “it is more than likely going to start a fire and more than likely going get pretty big pretty quick.”
