The wildfire smoke in Philly is forecast to last into the weekend — and be followed by storms

Impacts from Canadian wildfire smoke increased throughout the Philadelphia region Friday, degrading air quality enough to prompt a code purple alert, and force the closure or suspension of some city amenities and services.
It was the latest bad weather event in Philadelphia’s run of tough luck in July, which has so far resulted in record-setting heat and destructive storms that have marred back-to-back weekends. Smoky conditions arrived Thursday, and were bad enough Friday to prompt the closure of city pools and spraygrounds, and temporarily stop trash pickup.
“Our worsening air quality is a dangerous development,” Palak Raval-Nelson, commissioner of the city Department of Public Health, said in a statement. “I strongly encourage all residents to take action to protect themselves by staying indoors, unless they need to be outdoors.”
Likewise, the Philadelphia Zoo remained closed Friday, saying in a statement that its animals were being “closely monitored.” The city, however, stopped short of recommending the cancelation of outdoor events, and large productions like comedian Shane Gillis’ performance at Lincoln Financial Field and a Death Cab for Cutie performance at the Highmark Mann Center for the Performing Arts were still set to go on as of late afternoon.
Officials said that venue owners had been advised of the conditions, and were able to make their own decisions as to whether those events would happen.
Trash collection in the city was expected to cautiously resume Saturday, officials said. Resumption of services was contingent upon improvement in air quality conditions, which vacillated between code purple and the comparatively less severe code red Friday.

Pa. DEP says air quality should improve Saturday

The Pennsylvania Department of Environmental Protection early Friday evening said air quality continues to improve throughout the state and storms on Saturday will help.
The agency issued a Code Orange air quality alert for Saturday in Philadelphia, Bucks, Chester, Delaware, and Montgomery Counties. The rest of the state is expected to remain in the Code Yellow, or moderate range.
This is an improvement from the Code Red and Code Purple conditions that resulted Friday from the wildfire smoke from Canada.
Rain and thunderstorms on Saturday are expected to help, but improvements will be slower in Southeastern Pennsylvania because the rain will arrive later, the agency said.
During Code Orange alerts, people should avoid long or intense outdoor activities, the agency said. Sensitive groups, including children, elderly residents, and those with respiratory illnesses should avoid all outdoor activities.
The agency storngly advised people to check airnow.gov for current air quality conditions in their area, as conditions may change throughout the day.

Saturday evening gospel concert at Dell Music Center postponed due to air quality
The “Praise Under the Stars” gospel concert at the Dell Music Center scheduled for Saturday evening has been postponed, the center said Friday.
A new concert date would be announced soon, the center said.
“Due to the hazardous air quality conditions affecting our region as a result of the ongoing Canadian wildfires, Praise Under the Stars, scheduled for Saturday, July 18, 2026, at 7:00 PM at the Dell Music Center, has been postponed out of an abundance of caution,” the center said on its website.
“The safety and well-being of our guests, artists, vendors, and staff remain our highest priority. While we are disappointed to postpone this special event, we believe it is the responsible decision given the current environmental conditions,” the center said.
“A new concert date will be announced as soon as possible. All previously purchased tickets will be honored for the rescheduled event,” the center said.
“We sincerely appreciate your understanding, patience, and continued support of the Dell Music Center. Please stay safe, and we look forward to welcoming you back soon,” the center said.

Philly reduced its air quality alert and plans to resume trash collection as well as reopen city pools

Philadelphia officials said city sanitation services would cautiously resume Saturday, when smoky conditions brought to the area by Canadian wildfires are expected to improve.
City pools, which were closed Friday amid code purple air quality, were also expected to reopen, pending the air conditions the weekend brings, officials said at a Friday afternoon news conference.
“We will make judgment decisions as to when we will resume collections in terms of a start time tomorrow,” said Carlton Williams, director of the Philadelphia Office of Clean and Green Initiatives. “But we do plan on working all day Saturday and Sunday to ensure that last week’s trash and recycling is collected in time for our services to be on a regular schedule starting Monday.”
Palak Raval-Nelson, the commissioner of the city’s Department of Public Health, said air conditions had at least temporarily improved by Friday afternoon, moving from the more serious code purple to the less severe code red.
(function () {window.addEventListener(‘message’, function (e) { var message = e.data; var els = document.querySelectorAll(‘iframe[src*=”‘ + message.id + ‘”]’); els.forEach(function(el) { el.style.height = message.height + ‘px’; }); }, false); })();
Despite that change, air conditions remained unhealthy, and officials advised that residents remain inside if possible, and limit their exposure outside to no more than 90 minutes at a time.
Air conditions, Raval-Nelson added, could also change again back to code purple, and officials were monitoring the situation.
Pools, said city Parks and Recreation Commissioner Susan Slawson, would reopen Saturday if air conditions were code red or below. If air conditions creeped back into code purple territory, they would remain closed, Slawson said.
A number of large events were also slated to take place at venues in the region Friday and Saturday. Among them are a performance by comedian Shane Gillis at Lincoln Financial Field, and a concert from Death Cab for Cutie at the Highmark Mann Center for the Performing Arts, which were both still set to go on as planned Friday afternoon.
Officials said that venue owners had been advised of the conditions, and were able to make their own decisions as to whether those events would continue to go on.
“We provide them with the information, and they make their decisions,” said city Managing Director Adam Thiel.

Storms could clear wildfire smoke Saturday, but flooding is possible

The city is warning people to prepare for potential flooding Saturday as heavy rainfall is expected to douse the region.
The forecasted Saturday storms likely will clear the wildfire smoke that has hung over the city since Thursday, the National Weather Service said. However, these “multiple rounds of storms” may cause flooding.
The flood watch is in effect from 10 a.m. Saturday through 2 a.m. Sunday, the city’s office of emergency management said. Storms may produce rainfall of two or three inches per hour.
“Be prepared to take action in the event that flooding develops,” the city said. It directed people to a website offering tips and resources.
Berks, Carbon, Delaware, Chester, Montgomery, Lehigh, Bucks, Monroe, and Northampton Counties also are all at risk. So are portions of northern Delaware and parts of New Jersey, including Camden and Gloucester Counties.
“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” the city said. “Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas.”
Flooding may not be the only problem. Friday morning, the National Weather Service said high winds and a potential tornado could also hit the area Saturday. On Saturday, high winds from four “microburst” storms downed nearly 300 trees in Philadelphia and left tens of thousands of residents without electricity. Philadelphia remains under a disaster emergency declaration as it recovers from those storms.

Bebe Rexha’s FIFA Fan Festival performance appears to still be on

As FIFA Fan Festival at Philly’s Lemon Hill winds down in its last week of activity, Friday’s Bebe Rexha performance is still a go.
The dance pop artist’s free performance at Fan Fest is scheduled to begin at 7 p.m. with gates opening at 5 p.m.
So far, organizers haven’t announced any schedule changes. On Thursday, DEADMAU5’s free performance also went on as scheduled despite the air quality concerns.
The grounds are also scheduled to be open this weekend for the World Cup’s closing matches.

A Death Cab For Cutie and Japanese Breakfast concert at the Mann Center Friday is still on

Friday’s Death Cab for Cutie headlining show at the TD Pavilion at Highmark Mann was expected to proceed as scheduled.
That’s according to officials at the Highmark Mann Center for the Performing Arts. Neither Death Cab for Cutie nor Japanese Breakfast, who is opening, have commented so far.
Anticipation is high for the show, featuring Japanese Breakfast, whose front woman Michelle Zauner has Philly ties. Friday’s show would mark Zauner’s first Philly performance since announcing her pregnancy at her band’s Governors Ball show.
On social media channels, fans have started game-planning: discussing wearing N95 masks to the show as a precaution as questions about the air quality linger.
And while the show must go on (for now at least) at the Highmark Mann and Shane Gillis at the Linc, smaller shows, like a Friday night concert and movie night, are being canceled.
According to a statement, the Chicago 9’s performance at Lindenwold Park and Movies with Metro at Von Nieda Park in Camden are off, citing the air quality.

Shane Gillis says his comedy show at the Linc Friday is still on

Comedian Shane Gillis says his one-night-only show Friday at Lincoln Financial Field is a go.
“Not canceling cause of the smoke,” the Mechanicsburg, Pa., native and Eagles die-hard fan posted on his Instagram story, with a sneak peek at the outdoor stage.

Gillis is expected to perform his edgy, often controversial comedy to a near-capacity crowd. Unnamed special guests are also billed to make appearances.
The show starts at 8 p.m., when the air quality index is likely to improve.
Gillis cut his teeth in the Philly comedy scene after graduating from West Chester University. He landed a gig at Saturday Night Live but was fired from the show for having made homophobic and racist jokes on a podcast.
Since then, he’s landed a hit Netflix series in collaboration with Philly’s John McKeever and a successful stand-up special.

New Jersey is offering free masks to commuters
As smoke from Canadian wildfires continues to impact air quality across the region, New Jersey is handing out masks to commuters forced to be outdoors.
“I’ve directed NJ TRANSIT and the New Jersey Turnpike Authority to make select quantities of masks available to commuters and at rest areas along the Turnpike and Parkway. The Port Authority will also be distributing masks,” Gov. Mikie Sherrill said in a statement shared on social media.
Air quality across New Jersey was in the “unhealthy” range as of 10 a.m. Friday morning, with South Jersey faring worse than the northern part of the state.
A station in East Greenwich Township, Gloucester County, reported an air quality index of 191, while Atlantic City was 173, both in the unhealthy range.

During Phillies game, smoke-filled skies were ‘not ideal’ for players

The Phillies aren’t scheduled to play again until late Saturday afternoon, but Thursday’s game was moved up an hour early because air quality was expected to worsen after sunset.
The forecast proved correct. When the game started, the air quality index was at 157, according to airnow.gov, categorized as “unhealthy.” It rose to 166 by 8 p.m., with the Center City skyline no longer visible from South Philly. By 9 p.m., it was 192.
“It’s not ideal,” Phillies pitcher Aaron Nola said. “But it is what it is. Can’t really do anything about it. It’s one of those days where it was smoky. But I mean, it’s an outdoor stadium. You’ve got to get the game in and play through different conditions.”
Brandon Marsh said home-plate umpire Dan Iassogna, also the crew chief, repeatedly asked players throughout the game if they didn’t feel well or if the conditions were disruptive in the game.
“Yeah, multiple times they were checking with us, asking us players — which was cool to see — if we were good to go, and obviously we were all ready to go,“ Marsh said. ”That was good by them. I wasn’t expecting that, but that was good.”
The Phillies and Mets also altered their pregame routines. Neither team took batting practice on the field and spent “as little time as possible on the field,” interim manager Don Mattingly said.
“Just doing what you absolutely feel like you have to do after being gone for three days,” he added. “Not trying to absorb a bunch of energy when you’re getting heated.”

Smoke likely to stay until Saturday afternoon, National Weather Service says

Shifting winds may give Philly a break from the smoke today, but the air quality is likely to remain poor until at least Saturday afternoon, the National Weather Service said Friday.
Wildfires continue to burn in Western Ontario, and northwest winds are blanketing the region with particulate-filled air that gives the sky its hazy appearance, said meteorologist Joe DeSilva.
“As winds shift more northerly today, that’ll push the majority of the smoke south of our area briefly. A resurgence of the smoke is expected tonight as winds shift again,” DeSilva said.
The smoke is forecast out over the next 48 hours, and it’s difficult to predict what happens beyond that timeline, DeSilva said.
However, a storm system expected Saturday should clear the smoke out, he said.
That system will bring its own hazards. DeSilva predicted “multiple rounds” of showers and thunderstorms Saturday, bringing the potential for flash flooding. In addition, “damaging winds” are likely, with the potential for a tornado.
“It definitely looks like damaging winds will be the primary hazard type,” he said.

‘Hazardous’ air quality recorded in Chester as smoke lingers across the region
Air quality across the Philadelphia was poor Friday morning due to wildfire smoke from Canada, with most of the area in the “very unhealthy” zone.
The city of Chester was among the worse, hitting an air quality index of 312 at 7 a.m. Friday. A reading over 300 is considered “hazardous,” with air quality so poor it could be dangerous to everyone.
By 9 a.m., the number dipped down a bit to 279, solidly in the “very unhealthy” category.
An air quality station in Philadelphia The Inquirer is tracking peaked at 291 Thursday night, but had dropped to 250 by Friday morning.

Philly pools are closed and trash pickup suspended as residents are encouraged to stay indoors

Philadelphia pools and spraygrounds will be closed Friday and trash pickup is suspended due to “very unhealthy” air quality caused by Canadian wildfires.
“Our worsening air quality is a dangerous development,” Palak Raval-Nelson, the commissioner of the city’s Department of Public Health, said in a statement. “I strongly encourage all residents to take action to protect themselves by staying indoors, unless they need to be outdoors.”
As of 7 a.m., Philadelphia’s air quality index was 267, solidly in the middle of the “very unhealthy” range, which means the the general public is at risk for serious heath effects.
Especially at risk are residents with heart or lung conditions, who should take “extra special care” outdoors, Raval-Nelson said. Children, older adults, pregnant women, and people with weakened immune systems are also at higher risk.
Raval-Nelson said residents should avoid going outdoors unless necessary, and those that do leave should wear an N95 or KN95 mask.
“This situation is dangerous, and if we all take care and look out for each other we will get through this,” Raval-Nelson said at a news conference Thursday night.
People experiencing symptoms including trouble breathing, heart palpitations, nausea, or dizziness are encouraged to seek immediate medical attention.
Despite the warning, most city services will operate normally. The city is not recommending outdoor events be canceled, and employees working outdoors are being encouraged to take frequent breaks and mask up.

A ‘code purple’ air quality alert is in place across Pennsylvania

Philadelphia’s jinxed July, which had already featured a record-setting dome of heat and microburst storms that razed hundred of trees, now includes a smothering, suffocating smoke.
The smoke, which is expected to blanket the region at least through Friday, originated from fires burning in Western Ontario, said Sarah Johnson, a meteorologist at the National Weather Service’s Mount Holly office.
The Pennsylvania Department of Environmental Protection has declared a Code Purple Air Quality Alert for Friday. Code purple signifies very unhealthy air, meaning people should avoid long or intense outdoor activities, and sensitive groups should avoid all outdoor activities. The department suggested not using gas-powered lawn and garden equipment, and avoiding the burning of leaves or trash.
The smoke was swept in by winds that mixed to keep it closer to the ground.
“It’s just a factor of the winds at all levels kind of working together,” Johnson explained.
It is difficult to pinpoint when the air quality might return to normal, she said. Those forecasts come from state environmental protection departments and are usually no more than 48 hours out.
Rain forecast for Saturday could help suppress the smoke, Johnson said, but it’s too early to be sure.

What to know about the wildfire smoke in Philly and its health impacts

As Canada grapples with hundreds of active wildfires, the rest of North America is feeling the impacts with air quality alerts.
In Philadelphia and elsewhere, the air quality score is considered very unhealthy, particularly for the most sensitive people.
Whether you are planning to go out or stay home, here’s what three experts had to say about staying healthy and what precautions are needed:
What makes this smoke so toxic?
Exposure to this particular fire smoke is a serious matter due to “photochemical aging,” said Eric Balaban, a pulmonary and critical care fellow at Temple University.
As smoke travels, it interacts with oxygen, heat, and sunlight, creating a toxic profile that helps generate high levels of ground-level ozone and highly irritating aerosols, Balaban said.
Ground-level ozone is a pollutant that forms when nitrogen oxides and volatile organics emitted by vehicles, power plants, and industry react in sunlight, especially during hot days such as Thursday.
The pollutants aren’t the only problem.
The fine particulate matter within the smoke is small enough to cross from the lungs directly into the bloodstream, Balaban said, increasing the risk of heart attacks and strokes, in addition to causing acute chest tightness, shortness of breath, and dizziness in otherwise healthy people.
