Canada fire smoke evacuates thousands

Smoke from a wildfire that’s burned more than 4,000 acres and forced thousands to evacuate is causing 2024’s first widespread drop in air quality, according to the British Columbia Wildfire Service.

The Parker Lake Fire, burning in the northeast section of the province, forced more than 3,000 residents from the nearby Northern Rockies Regional Municipality and Fort Nelson First Nation to evacuate.

“All remaining residents are urged to evacuate the community immediately,” a press release from the Northern Rockies Regional Municipality said. “As the safety of emergency personnel remaining in the community becomes the priority, residents remaining in place need to be aware that emergency medical services are not available, nor are groceries or other amenities. Utilities may be affected to support fire response efforts.”

While the evacuations are limited to the immediate areas near the wildfire,  the smoke is triggering air quality alerts throughout Canada and the northern U.S., according to Canada’s Weather Information Service and the AirNow Fire & Smoke Map.

Air quality is at the most dangerous reading of “hazardous” in areas directly southeast of the fire near the community of Grande Prairie. People  should avoid outdoor activities during hazardous air quality, especially people with pre-existing heart or lung conditions, or older adults, children, and pregnant women.

The smoke has caused “very unhealthy” air quality alerts in numerous communities in central and southern Alberta. Communities in southern Saskatchewan, Manitoba, and Ontario, as well as areas in Montana, North Dakota, and Minnesota have “unhealthy” air quality.

The Parker Lake Fire is the first wildfire of 2024 to cause widespread air quality impacts, the beginning of what fire experts expect to be a growing trend throughout the year. Fire crews throughout British Columbia are actively fighting 134 wildfires, primarily in the Prince George region of the province, according to the province’s wildfire service.

Most of the fires are considered “under control,” with only four wildfires designated as “being held” and 13 others “out of control.” Another 102 BC fires have started since the beginning of the year, but are considered “out.”

Canada’s early and busy start is on par with the fire service’s outlook for the spring 2024 season that was released in March. “The current long-range forecasts suggest a high potential for an active spring wildfire season in British Columbia,” the report says. “While recent snowfall may seem beneficial, its impact on the upcoming wildfire season is expected to be minimal due to sublimation (solid to vapor) and the dry nature of snow in Interior regions. The low snowpack will limit surface runoff, stream flows, and fuel moisture recharge, which could limit drought recovery into summer 2024.”

The intensity of the summer wildfire season is in British Columbia largely depends on the amount and duration of rainfall during May and June, the rainiest months in the BC Interior. Continuous rain could reduce the likelihood of wildfires, but meteorologists are currently skeptical that sufficient rainfall will occur.

The 2023 wildfire season in British Columbia ended with 2,293 wildfires and burned more than 7 million acres, costing the province $1.1 billion. Just over 70 percent of the wildfires were lightning-caused.

Canadian wildfire smoke moves into Northeast U.S.

New York City has some of the worst air quality in the country this week because of smoke that’s drifted south from wildfires in Canada. The city had an orange glow Tuesday morning, with the sun obscured by a smoky haze, reported by CNBC. The New York Department of Environmental Conservation issued an air quality health advisory Tuesday for several counties and surrounding suburbs. Ratings for air quality reached into the 150s on Tuesday, according to AirNow. Those levels are considered unhealthy for all people and significantly above exposure recommendations from the World Health Organization.

The sky over the city had an orange glow on Tuesday morning and the sun was largely obscured. Officials warned residents to limit time outdoors and emphasized that people with respiratory illnesses or heart disease are especially vulnerable to the dangerous air quality conditions. The New York Times reported that smoke brought hazy skies to parts of New York State and also Vermont on Tuesday, and air quality alerts were also issued across large swaths of Minnesota. Hundreds of wildfires burned across Canada, exacerbating an active wildfire season that is expected to worsen, and sending smoke into much of the U.S.

Haze blanketed much of Ottawa and Toronto, while all of New York City was under an air quality alert; by the afternoon, the Manhattan skyline was obscured.

The Oregonian reported that smoke is also causing unhealthy air quality across Oregon, but just two sentences of the report by Gosia Wozniacka were available to non-subscribers. The Seattle Times, however, reported that Canada’s intense wildfires now spread from the western provinces to Quebec, with hundreds of active fires. On Tuesday, the U.S. Environmental Protection Agency issued a poor air quality alert for New England, a day after parts of Illinois, Wisconsin, and Minnesota received similar advisories. Last week, U.S. officials as far south as Maryland, Virginia, and Pennsylvania reported being affected by the wildfires.

The EPA said the smoke will linger for a few days in New England.

“It’s not unusual for us to get fire smoke in our area. It’s very typical in terms of northwest Canada,” said Darren Austin, a meteorologist and senior air quality specialist with the Rhode Island Department of Environmental Management. But the smoke usually has remained aloft and doesn’t affect people’s health, he said.

The Quebec-area fires are both large and relatively close, about 500 to 600 miles (roughly 800 to 970 kilometers) away from Rhode Island. And they followed wildfires in Nova Scotia, which caused a brief air quality alert on May 30, Austin said.

In Connecticut, smoke from Canadian wildfires lingered overnight on Monday and covered the entire state by Tuesday morning. WTNH-TV News reported that the smoke boosted fine particulate levels starting Monday evening, pushing them into the “unhealthy for sensitive groups” category, according to the Connecticut Department of Energy and Environmental Protection.

The Northeast smoke is the result of more than 150 fires in Canada; it has drifted toward Connecticut and stalled in the Northeast U.S. by an upper-level, low-pressure system, according to Connecticut’s DEEP.

Those with asthma or lung disease, and/or the elderly are at risk if they spend a long time outside. Last week, the American Lung Association issued an air quality alert for increased fine particulate matter levels.

Wildfires in Southern Oregon and Northern California continue to have a large effect on the air quality in those areas and neighboring states. The fires that are the largest producers of smoke in California are Monument, River, McCash, Antelope, Dixie, and Caldor. Several fires in Western Oregon are also contributors. After receiving rain in the last few weeks fire activity has decreased significantly in Washington, Idaho, and Montana.
