Wildfire smoke brings worst air quality to Portland, Seattle – Beaumont Enterprise


SEATTLE (AP) — Smoke pollution from wildfires raging in California and across the Pacific Northwest worsened in San Francisco, Seattle and Portland, Oregon, on Friday, giving those cities and others in the the region some of the world’s worst air quality.

Public health officials warned residents to keep indoors with the windows shut, to set air conditioners to run on recirculated air instead of fresh, and to use air purifiers if they had them. Meanwhile, they wrestled with whether to open “smoke shelters” for homeless people or others lacking access to clean air amid the COVID-19 pandemic and concerns about herding people indoors.

“The same population that is most vulnerable to the virus is also most vulnerable to the smoke,” Seattle Mayor Jenny Durkan noted during a news conference.

The sky turned a hazy, grayish white across the Northwest as winds that had previously pushed much of the smoke offshore shifted, bringing unhealthy levels of near-microscopic dust, soot and ash particles to Portland, Seattle, and Vancouver, British Columbia. San Francisco also continued to suffer from smoke pollution; those four cities topped the list of major cities with the worst air quality Friday, according to IQAir.com, which tracks air quality around the world.

The smoke was expected to linger through the weekend, another reminder of the vast and severe effects of climate change. The particles are small enough that they can penetrate deep into the lungs, and health effects can include chest pain, arrhythmia and bronchitis. Those with preexisting conditions such as heart and lung disease or asthma are especially at risk.

Seattle ordered parks, beaches and boat ramps closed through one of the last hot weekends of the summer to discourage outdoor recreation, and officials were opening a clean air shelter Friday afternoon that can hold 77 people. The facility, which had been set up as an overflow COVID-19 care facility, is large enough to allow for social distancing, they said.

San Francisco officials were also opening “weather relief centers” that will stay open through the weekend, said Mary Ellen Carroll, director of the city’s Department of Emergency Management. City buses were free for everyone so those who need to can reach the centers.

Much of California was covered by a thick layer of smoke being pumped into the air by dozens of raging wildfires. In San Francisco, the gray air smelled of burned wood and visibility was clouded by “very unhealthy” air, according to the Bay Area Air Quality District.

Residents were also asked to avoid activities that could further degrade the air quality, including unnecessary driving, lawn mowing and barbecuing.

Working in University Place, a Tacoma suburb, Washington state Department of Ecology spokesman Andy Wineke said the smoke had obliterated his typical view of the Olympic Mountains.

“I can barely see my neighbor,” he said.
