wildfire

EAST RUTHERFORD, N.J. — Showers and thunderstorms triggered a flash flood warning for Manhattan and northeastern New Jersey on Saturday, but the rain also helped blow out the smoke from Canadian wildfires that had choked the tristate area for days and threatened to disrupt Sunday’s World Cup final at MetLife Stadium.

Concerns about hazardous air quality led the White House and FIFA to hold informal discussions Friday over the possibility of moving the game, with the most likely venue being Hard Rock Stadium in Miami Gardens, Fla.

On Friday, before the storms, the Air Quality Index (AQI) in East Rutherford was around 160, which was considered unhealthful. But that was down from a “very unhealthful” reading of 245 on Thursday.

By 6 p.m. EDT on Saturday, that level had dropped further, to 89, posing only a moderate health concern for a very small number of people. That number was expected to continue falling into the early hours of Sunday, and the level at kickoff was projected to be 66, although forecasters warned that shifting winds could bring smoke back into the area, causing temporary spikes in the AQI.

July 18 (UPI) — Ontario Premier Doug Ford on Saturday shot back at President Donald Trump, saying his comments about Canada’s efforts to control the ongoing wildfire crisis are a “shame” and “totally unacceptable.”

Trump threatened Friday to impose tariffs on Canadian imports and accused the country of “willful negligence” in its management of the blazes.

“I find it a shame, the administration in the U.S. and Congress people, writing these letters and blaming us,” Ford said in a press conference on Saturday. “They have a very short, short memory. We had the water bombers, everyone ready, going over to California — it was last year. We sent hydro linemen down to the Carolinas and Georgia to help out.”

Ford added, “That’s what neighbors do, right? You don’t get on and start threatening and criticizing because, guess what? One day it’s going to be your turn.”

As of Saturday, there were 959 active wildfires burning through Canada, 102 of which started in the past 24 hours, Canadian Interagency Forest Fire Centre reported.

The blazes have left more than 100 million Americans under air quality alerts, from Minnesota to Virginia.

“We are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush therein, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable!” Trump wrote on Truth Social.

Despite the dispute, Ford said Canadians would stand at the ready should Americans need support in the future.

“We’re going to be down there without hesitation to support our neighbors, which we should be,” he added.

Drone video shows the scale of a major wildfire in northern Spain where more than 150 square kilometres have burned across an 80-km perimeter.

With the World Cup final less than 24 hours away, an unlikely factor is grabbing the attention of organisers, fans and players alike.

The lingering smoke from the Canadian wildfires sparked earlier this week has engulfed the northeastern region of the United States, raising questions about its impact on the Spain vs Argentina final in New Jersey on Sunday.

A visible haze hung over the twin World Cup host states of New York and New Jersey on Saturday, with inclement weather causing disruptions.

At one point on Friday, New York rated as the city with the worst air quality in the world.

The World Cup final between the European champions and current title holders kicks off at 3pm local time (19:00 GMT) on Sunday in East Rutherford, New Jersey.

Here’s what we know about the smoke, weather and World Cup final:

Is there a haze in New York and New Jersey before the World Cup final?

Smoke from the Canadian wildfires is hanging over the region, reducing visibility and affecting air quality in most northeastern US states.

Warnings of unhealthy air quality remained in effect across a wide area of the US east coast on Saturday.

However, experts predict conditions will improve for the big showdown in New Jersey tomorrow.

The air quality index forecast shows an improvement from unhealthy air to “moderate” air quality for sensitive groups from Saturday to Sunday in East Rutherford, which means little to no health risk for the general public on the day of the final.

How is the weather and what’s the forecast in New Jersey before the Spain vs Argentina final?

A thunderstorm passed through the area on Saturday afternoon, causing heavy rain and loud thunder at the New York New Jersey Stadium, renamed from MetLife Stadium.

State police urged people to leave the stadium seating bowl and field and take shelter. Volunteers and staff dashed inside for cover as ponchos were handed out. The sky was the same thick, soupy grey it had been for days.

New Jersey Governor Mikie Sherrill warned residents about the potential for damaging winds, tornadoes, flash flooding and large hailstones.

FIFA said it was in close contact with local authorities as it continues to monitor the impacts from the wildfire smoke and the storms on the stadium conditions for the final.

Have the weather and smoke disrupted preparations for Spain or Argentina?

Spain’s last training session ahead of the final at a nearby Melanie Lane Training Ground was suspended because of storms and lightning in the area.

The Spanish football federation (RFEF) said that was in accordance with US storm safety protocol.

“The players are currently taking part in a warm-up session indoors,” RFEF added.

FIFA said that there would not be another time slot for the team to train.

Argentina had an outdoor training session at their scheduled time of 1:30pm (17:30 GMT), with players showing no concerns about air quality or the weather.

Will the wildfire smoke affect the World Cup final?

The haze will mostly clear from New Jersey just in time for the final, thanks to thunderstorms passing through the area, meteorologists say.

“This storm front will largely move the smoke out of the northeast before the final between Spain and Argentina,” said Tyler Roys, a senior meteorologist at online weather service AccuWeather.

“There could be some lingering smoke that would make things hazy, but very faint,” Roys said. “In terms of the thickest smoke, the smoke that has really been eye-popping and leads to poor air quality, that is not expected across New York City or much of the northeast.”

Jeff Berardelli, chief meteorologist and climate specialist at WFLA-TV, echoed the forecast, saying the storm front would “sweep the atmosphere clean”, leaving only a thin smoke that World Cup spectators may still smell in the air.

“It won’t be dangerous anymore,” Berardelli said. “It’s going to be dramatically better.”

Temperatures are forecast to be around 27C (80F) with light breezes and low humidity for kick off.

“You couldn’t have asked for much better weather for the World Cup,” Berardelli added.

Both experts expect the heavier smoke on Sunday to be concentrated closer to the fires, hanging over parts of the Midwest and Great Lakes region.

Berardelli said they are burning longer and faster because of climate change.

Plumes of smoke from wildfires in Canada are pouring into major US cities across the Midwest, Northeast and mid-Atlantic. Polluted air is affecting more than 100 million people and is creating concern ahead of Sunday’s World Cup final.

United States President Donald Trump has threatened to impose additional tariffs against Canada, as a penalty for the wildfire smoke that has clouded cities across North America.

On Friday, Trump complained about the air quality on social media, as officials in Canada continue to battle 896 active blazes across the country.

Roughly 200 are burning in the province of Ontario, where Premier Doug Ford said 81 are still out of control. Trump, however, blamed the fires on Canadian governance.

“We are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush,” Trump wrote.

“The United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable!”

He pledged to call Prime Minister Mark Carney, accusing the Canadian leader’s government of negligence.

“The cost is incalculable,” Trump added, saying the expense would be added to existing tariffs against Canadian exports to the US.

The post is the latest example of the US president wielding the threat of heightened tariffs to impose a wide range of demands on foreign countries.

Since returning to the White House for a second term in January 2025, Trump has ratcheted up pressure against Canada, using tariffs as a means of pressuring the country to increase border security and change trade practices he considered unfair.

Trump has also pushed Canada to cede its sovereignty and become the “51st” US state.

Scientists have attributed the proliferation of wildfires across North America to a range of factors, including hot and dry conditions worsened by climate change.

But the right-wing Trump has repeatedly blamed left-leaning and centrist politicians for mismanagement when powerful wildfires erupt.

Trump, for example, repeatedly attacked California Governor Gavin Newsom when his state was fighting wildfires around the city of Los Angeles in 2025.

He blamed the fire destruction on the state’s approach to water management and its endangered species protections.

“I will demand that this incompetent governor allow beautiful, clean, fresh water to FLOW INTO CALIFORNIA! He is the blame for this,” Trump wrote at the time, though experts say his accusations had little basis in fact.

During his first term, Trump also attacked California, saying that the state should have raked its forest floors to prevent wildfires.

“I said, you’ve got to clean your floors. You’ve got to clean your forests,” Trump told a rally in 2020.

Scientists say that multiple factors can contribute to large wildfires, including heightened heat, drought and overly repressive fire policies that prevent natural burns, resulting in overgrown landscapes.

The risk of damage is also heightened by the increasing number of people living in areas where the wildlands meet urban development.

In mid-July, Ontario saw its largest conflagration of the year so far, when several smaller fires merged in Wabakimi Provincial Park, destroying First Nations communities.

Ford, Ontario’s premier, said on Friday morning that 10 communities had been evacuated.

He thanked leaders across Canada, as well as in US states like Massachusetts and Minnesota, for providing support.

“Neighbours have each other’s backs, which is why Ontario has always been there for our American partners in their time of need,” he wrote on social media.

But Republicans, including Trump and US Representative Bill Huizenga of Michigan, have used the recent blazes to criticise Canada for its fire policy.

“Canada’s inability to mitigate, contain, and prevent its wildfires must be addressed,” Huizenga wrote on social media on Thursday. “These annual fires significantly harm not only our health and quality of life, but also our economic prosperity.”

On Friday, Trump reiterated his position that Canada’s fires could have been prevented through debris removal.

“Canada has refused to engage in basic Forest Management and Debris Removal, knowing that such refusal will lead to exactly this result,” Trump wrote.

“This is Willful Negligence, and becoming a yearly occurrence, costing the United States Billions of Dollars, which cost of this pollution must of necessity be added to the TARIFFS Canada is currently paying.”

The wildfire smoke has prompted concerns about the viability of hosting the FIFA World Cup final in New Jersey this weekend.

But the Trump administration itself has faced pushback over its wildfire preparedness.

The New York Times reported on Friday that the Trump administration had slashed funding for wildfire research, including laboratories that study the effects of wildfire smoke on human health.

July 16 (UPI) — Thick smoke from Canadian wildfires poured into northeastern quarter of the United States on Thursday after similarly darkening skies across and prompting health warnings across much of the Great Lakes region.

Dangerous levels of smoke were noted across Canada and the northeastern and midwestern United States, sparking memories of the historically severe wildfire smoke outbreak in 2023.

Entire states including New York, New Jersey, Connecticut, Delaware, Massachusetts, Michigan, New Hampshire, Ohio, Pennsylvania, Rhode Island and Wisconsin were under air quality alerts.

By early Thursday, Minneapolis, Duluth, Minn., and Detroit were among the most heavily impacted areas of the country.

Very heavy smoke from large wildfires in northern Minnesota and northwestern Ontario spread over Minnesota from late Wednesday into Thursday morning, the Minnesota Pollution Control Agency reported.

Hourly observations of smoke concentrations broke records for the Twin Cities on both days, the agency said.

In Detroit, businesses and attractions closed due to poor air quality.

A planned concert by rocker John Mellencamp at Pine Knob Music Theatre in Clarkston, Mich., was canceled while some workers inside Ford Motor‘s Michigan Assembly plant in Wayne, Mich., were hospitalized amid the smoky haze and intense heat, the Detroit Free Press reported.

Michigan’s statewide air quality alert was extended through Friday before cooler weather was expected to move the smoky pall out of the Great Lakes region.

In Chicago, the city closed all of its public beaches and outdoor pools, while Milwaukee recorded the worst air quality in its history — a record-breaking Air Quality Index measured at over 600, according to the Milwaukee Journal.

Further east, smoke from the Canadian wildfires enveloped New York City, prompting Mayor Zohran Mamdani to urge residents to “take precautions to stay cool and out of harm’s way” while dealing with both the smoke and high temperatures.

“In our city, we pride ourselves on being resilient,” the mayor told reporters early Thursday. “Today is not a day to say, ‘In spite of the air quality, I’m going to do everything I was going to do yesterday.’ This is very serious. We are reaching into a level of air quality that is dangerous for every single New Yorker.”

If your destination falls victim to a wildfire or other extreme event, what should you do, and can you get your money back? A consultant for independent financial research company Defaqto has explained what Brits need to look out for

Many Brits will be heading off to Spain for the busy summer season in the coming weeks, and no doubt seeing the headlines about wildfires will cause some alarm if you’ve got a holiday booked.

Wildfires broke out in the Almería province of Spain last week. So far 13 people have been confirmed dead, among them, seven Britons. Almeria is part of the Andalusia region, and is popular with expats and holidaymakers. The Foreign, Commonwealth & Development Office (FCDO) recently updated its advice for anyone travelling to Spain.

It said: “If you are in an area affected by the wildfire follow instructions from local authorities and emergency services at all times, avoid travelling into or through the affected area, and follow updates from the emergency services.”

People who were planning trips to Andalusia and other areas of Southern Europe suffering from wildfires and other extreme weather events may be wondering where this leaves them. Anna-Marie Duthie, an insight consultant at independent financial research company Defaqto, gave her thoughts.

Anna-Marie said: “If your airline cancels your flight due to wildfires, they should offer you the chance to rebook, or provide a full refund. If your holiday was booked as a package, this refund should cover all elements — flights, accommodation and transfers.

“But if you’ve booked everything separately, you’ll need to deal with each provider independently. Your airline may refund your flight, but your accommodation provider may not if the property is unaffected. This is why it’s essential to speak directly with providers in the first instance and check with your insurance provider regarding the cover they include.”

Travellers should regularly check the FCDO website to see tailored advice for their destination and ensure no travel warnings are in place. Anna-Marie said: “If government advice changes, advising against travel to the area after you have booked your trip, then you may be covered for cancellation or curtailment.

“You may also be covered for additional travel and accommodation costs should your trip be disrupted due to a catastrophic event, if your insurer offers this cover or you’ve paid to include it.”

Anna-Marie believes that extreme weather events could affect the travel insurance industry in future, saying: “Whilst it’s difficult to know exactly how travel insurance may change over the next decade, longer term there is a chance that we may end up seeing less insurable destinations and increased premiums. What we do know, however, is that travel insurers are used to having to adapt to an ever-changing world.”

But she added: “It is unlikely and we are yet to see any immediate changes to policies because of the current heatwave. It is unlikely insurance providers will change their policies in the near future to incorporate extreme heat. Current clauses may refer to ‘severe’ or ‘extreme’ weather, but the definitions for these can vary and currently no providers go as far as to specify criteria such as maximum temperatures.

“Where the heat causes events such as the current wildfires, this is a separate consideration and would be classed as a catastrophe or natural disaster. Cover for this will all depend on your insurer’s definitions and extent of benefits.”

Monitor ranks Toronto as having the worst air quality on earth, surpassing Kinshasa, DR Congo, and New Delhi, India.

Toronto’s air quality has ranked the worst among all major cities in the world as smoke from wildfires in northwestern Ontario blankets the skies and spreads into the northeastern United States, triggering multiple health warnings and evacuations.

Wildfires continued burning through sparsely populated areas hundreds of miles from Toronto, Canada’s largest city, on Wednesday, sending smoke over a wide area, although cities in the area are not being threatened.

Environment Canada reported an Air Quality Health Index reading of 10+, classified as “very high risk”, for Toronto. Forecasts suggested that hazardous conditions could persist through Thursday night.

IQAir, a Swiss air quality technology company, ranked Toronto as having the worst air quality across the globe, surpassing the Democratic Republic of the Congo’s Kinshasa and India’s New Delhi.

“The biggest contributor to Toronto’s spike in air pollution right now is wildfires, though the higher-than-average temperatures are also playing a role,” Armen Araradian of IQAir told the AFP news agency.

While this year’s wildfire season in Canada has been fairly muted compared with recent years, there are more than 800 active fires nationwide.

A video that went viral on social media showed a Canadian National train surrounded by fire near Armstrong, Ontario. Canadian National employees in the area and residents of Armstrong were evacuated on Monday night, the railroad operator said in a statement. It suspended rail operations near Armstrong as a precaution.

Smoke from the wildfires also worsened air quality across the border in the US, with the states of Pennsylvania, New York, Connecticut, Massachusetts, Maine and New Hampshire particularly affected.

Authorities in New York City have issued an alert over unhealthy air quality, urging residents to reduce strenuous outdoor activity and take extra breaks if they are outside on Wednesday and Thursday.

The National Weather Service said smoke could linger until the end of the week.

“We probably haven’t seen the worst of it yet for New York City. We probably haven’t seen the worst of it yet for the Great Lakes and upstate, and New England yet either,” Dan Westervelt, Lamont associate research professor at Columbia University, told the Reuters news agency.

More than 80,000 people are expected to attend the FIFA World Cup final at an open-air stadium in New Jersey on Sunday, with another 50,000 planning to watch the game from New York City’s Central Park, where skies appeared hazy.

New York Governor Kathy Hochul urged people, especially those with health conditions, to exercise caution.

The Canadian government has said that wildfire season began more slowly this year than in 2023 or 2025 – the two worst seasons for wildfires – but warned that fires were likely, due to warmer-than-usual temperatures across the country.

It said some 835 active fires were burning across the country on Wednesday, with 112 considered out of control, and most in the central provinces of Manitoba, Saskatchewan and Ontario.

They have burned 1.9 million hectares (4.7 million acres) so far.

Greg Evans, a professor of chemical engineering and applied chemistry at the University of Toronto, said the city had been simultaneously hit with severe heat and wildfire smoke.

“I expect that this will occur more frequently over the coming decades, so cities and residents need to prepare for this in the future,” he said.

A 93-year-old British woman has died in hospital after suffering burns to about 20% of her body in the Spanish wildfires. Her death was confirmed on Sunday afternoon, bringing the total number of fatalities from the fires to 13.

A stark warning has been issued to Brits travelling to Spain as the country continues to battle ferocious wildfires.

A 93-year-old British woman has died following injuries sustained in the deadly wildfires that tore through southern Spain, authorities confirmed this morning. The Andalusian government revealed the woman was rushed to hospital on Friday after sustaining burns to roughly 20% of her body.

Her death was confirmed on Sunday afternoon, pushing the total death toll from the blazes to 13.

The UK’s Foreign, Commonwealth and Development Office (FCDO) has issued a travel alert regarding the fires in Los Gallardos, Almería, in Andalucía. It urges those in the area to:

• follow instructions from local authorities and emergency services at all times
• avoid travelling into or through the affected area
• follow updates from the emergency services
• for emergencies, call 112

The FCDO notes that anyone concerned about someone in the area can call +34 677 904 624 provided by the Psychological Intervention Group for Emergencies and Disasters. English speaking staff are available. Consular assistance can be found by calling +34 917 146 300 if you’re in Spain, and +44 (0)20 7008 5000 if you’re in the UK.

At least four victims in Andalusia are believed to be British, after four bodies were discovered in a burnt-out vehicle with its steering wheel on the right-hand side.

This comes after reports on Sunday that two British hikers were found alive but severely burnt. The man and woman, who remain unnamed, are believed to have suffered burns to 40% of their bodies, according to Spanish national broadcaster RTVE.

The pair was located by a Civil Guard team, who revealed they had already swept the area, but had a gut feeling they needed to return. Speaking to RTVE, the Civil Guard officers described finding the two British nationals alive just as darkness was closing in.

Sergeant Pedro Barre told the broadcaster: “That experience we accumulate over the years is what tells you: take another look, give it one last try, check again just in case.”

He explained that the team called out and blew whistles, before eventually detecting a noise they initially thought might be an echo.

Fellow rescuer Rafael Zea added that given the severity of the couple’s injuries, it must have taken a “Titanic effort” for them to raise their voices loud enough to be heard. Firefighters and emergency services helped rescue the pair after more than two hours trapped.

Both individuals are currently reported to be in a serious condition in hospital, though their lives are not thought to be at risk. Spanish authorities believe all the victims were foreign tourists, who are thought to have attempted to escape on foot after apparently abandoning their vehicles and trying to flee through rugged terrain.

Antonio Sanz, head of Andalusia’s emergency services, previously said that authorities had completed post-mortem examinations and DNA samples were collected to identify them.

Spain has been hit by frequent and severe heatwaves in recent years, with temperatures regularly soaring above 40C. In June, Spain endured several days of record-breaking heat, with more than 1,000 excess deaths attributed to the scorching conditions.

Dr Thomas Smith, Associate Professor in Environmental Geography, London School of Economics and Political Science, explained why Spain is suffering so intensely from the fires.

“The extreme wildfire behaviour we’re seeing in Spain is closely linked to the extreme heatwave weather conditions. Fire behaviour (how quickly a fire spreads and how intensely it burns) is heavily influenced by the weather. Research shows that key measures such as rate of spread and the size of flames increase exponentially as fire weather becomes more severe, meaning that relatively small increases in extreme fire weather can produce disproportionately more dangerous fires,” he said.

“When weather conditions reach record-breaking levels, we should expect the potential for record-breaking fire behaviour, particularly when strong winds are present to accelerate fire spread and make suppression much more difficult.

“Climate change is increasing the frequency and intensity of the extreme heat and fire weather conditions that create these dangerous environments. While individual fires are influenced by many factors, including ignition sources, vegetation, and land management, climate change is inextricably linked to the record-breaking weather that is driving the conditions for these extreme wildfires.”

July 10 (UPI) — A huge wildfire raging in southern Spain killed at least 11 people with another 19 unaccounted for, authorities said Friday as more than 700 firefighters and troops, nearly 200 firetrucks and 16 aircraft battled the flames.

The Andalusian government said in a post on X that all indications pointed to the main blaze, which had already burned through more than 3,000 acres near Los Gallardos in Almeria province, being sparked by a fallen power pole before spreading to woods nearby.

Warning casualty numbers could increase substantially, Andalusian President Juanma Moreno said eight people were injured, four of them seriously.

“I’m on my way to Almeria. The consequences of Los Gallardos are devastating. Right now, all efforts are focused on controlling the fire and preventing further loss of human life,” he said in an update online.

The fatalities occurred in and around Bedar village, just northwest of Los Gallardos, with Andalusia’s health minister saying he believed four of those killed whose bodies were found in a car were likely Britons.

Health and Emergencies Minister Antonio Sanz said he had reason to believe they were British because the vehicle was right-hand drive whereas European cars are all left-hand drive — with the exception of Ireland, Cyprus and Malta.

The Spanish armed forces’ Military Emergencies Unit said in a post on X that it had 220 soldiers and 70 fire vehicles on the scene “attacking the frontline of the wildfire head-on to contain its advance.”

The provincial government said around 600 area residents remained evacuated.

More than 200 miles away in western Malaga Province, 1,000 people were evacuated from two residential complexes in the mountain village of Benahavis as a precautionary measure due to an “urban wildfire” that broke out on Thursday afternoon, the government said in a statement.

Authorities said more than 230 firefighters and other emergency personnel and 10 firetrucks were continuing to work to bring the fire under control and that the region’s Wildfire Prevention and Suppression Plan had been activated.

Residents forced to leave their homes were accommodated in a sports center, by the Red Cross and with family and friends or in local hotels.

Weeks of unseasonably hot weather across western and southern Europe, including three heatwaves with temperatures topping 40 degrees Celsius, has triggered a series of wildfires that have burnt at least 49,000 acres across Spain, Portugal, Greece and France.

June 28 (UPI) — Three firefighters were killed while battling a wildfire in western Colorado, the Department of the Interior announced Sunday.

Two others were being treated for burn injuries sustained in the Saturday “burnover” incident at the Knowles and Gore fires in Mesa County near the Colorado-Utah border, officials in a statement.

The identities of the fallen Wildland Fire Service and Forest Service firefighters were not immediately released pending notifications of their relatives.

Colorado Gov. Jared Polis said he was “devastated about the loss of three heroic firefighters who died in the line of duty in Western Colorado.”

In a statement, the he praised “the men and women who serve on the front lines of these fires risk their lives to keep us safe and to protect the lands and communities we love.

“To the loved ones of those lost, and to their fellow crew members — some who are still battling the flames — know that the State of Colorado mourns alongside you.”

Polis said the Colorado National Guard, the federal Bureau of Land Management and local officials and firefighters have been deployed to fight the Snyder-Mesa Fire, which on Sunday was estimated to be more than 28,000 acres, and to recover the bodies of the three fallen firefighters.

The governor said the two surviving firefighters had been extracted by helicopter.

On Saturday he activated the State Emergency Operations Plan and directed the Colorado Department of Public Safety to take responsibility for all response, recovery and mitigation efforts on the Snyder Mesa Fire.

The deaths came as powerful wind gusts, extremely low humidity and the threat of dry lightning fueled an outbreak of large wildfires across the southwestern United States.

Utah has been the hardest hit. Including the deadly blaze along the Colorado border, multiple fires exceeding 10,000 acres have erupted over the past week across the state. The Cherry and Iron Fires southwest of Provo, along with the Cottonwood Fire in south-central Utah, are among the largest active wildfires.

The weather pattern responsible for the heightened wildfire danger is expected to persist through much of the week, forecasters say.
