Northwest heat wave and bad air from wildfires pose danger

Temperatures were expected to soar to triple digits again Friday in Portland and into the mid-90s in Seattle as a heat wave bakes the Pacific Northwest, and forecasters said hot weather and wildfire smoke would pose a problem through the weekend.

An air quality alert was issued through Saturday night for much of Washington because of smoke drifting in from blazes in the eastern part of the state and British Columbia. However, forecasters said the hazy sky could drop temperatures slightly lower than predicted Friday and Saturday.

Temperatures in Portland reached 103 F (39 C) on Thursday — 20 degrees above average. In Bellingham, the temperature hit 100 F (38 C) for the first time on record, while Seattle topped out in the 90s.

It's the second major heat wave in less than two months in a normally temperate region where many don’t have air conditioning. Record-breaking hot weather in late June caused hundreds of deaths in Washington state, Oregon and British Columbia when the thermometer went as high as 116 F (47 C).

detailed scientific analysis found the June heat was virtually impossible without human-caused climate change. Meteorologist Jeff Masters with Yale Climate Connections said a similar study would need to be done with other heat waves, but there’s a general link between global warming and worsening heat waves.

“If you increase your baseline temperature, you greatly increase your odds of extreme heat events,” said Masters, co-founder of the private Weather Underground company.

Much of the Northwest was under an excessive heat warning through Saturday. The National Weather Service said heat advisories and warnings were also in effect from the Midwest to the Northeast and mid-Atlantic through at least Friday.

Oregon Gov. Kate Brown has declared a state of emergency and activated an emergency operations center. City and county governments have opened cooling centers, extended public library hours and waived bus fare for those headed to cooling centers. A 24-hour statewide help line will direct callers to the nearest cooling shelter and offer safety tips.

Authorities scrambled to provide relief to the vulnerable, including low-income older people and those living outdoors. Oregon volunteers handed out water, portable fans, popsicles and information about cooling shelters to homeless people living in encampments along the Columbia River on the outskirts of Portland.

People experiencing homelessness are often reluctant to go to cooling centers because they don't want to leave their possessions unattended or don't have transportation, said Kim James, director of homeless and housing support for Cascadia Behavioral Healthcare, a nonprofit group that serves the homeless and those with mental illness.

Scott Zalitis, who was shirtless in the heat, ate lime-green popsicles handed out by the group Thursday and told volunteers that the temperature at his campsite reached 105 F (41 C) the day before.

“It’s miserable. I can’t handle the heat no matter what. So, I mean, it’s hard to stand. Even in the shade it’s too hot," Zalitis said. “You want to stay somewhere that’s cool, as cool as possible.”

The encampment, where rusted-out cars and broken-down RVs mixed with tents and piles of garbage, was in sharp contrast to downtown Portland, where sweaty pedestrians cooled off by running through a large public fountain in a riverfront park.

The city closed all seven of its outdoor pools Thursday afternoon because of soaring temperatures and said the pools also would close at 2:30 p.m. Friday. Before the closures, the line of people hoping to cool off stretched for more than a city block.
