The death toll from the fires in California, Oregon and Washington stood at 31 and was expected to rise sharply. Most of the fatalities were in California and Oregon.
Oregon's emergency management director said officials were preparing for a possible mass fatality event if many more bodies turn up in the ash.
And the state fire marshal resigned after abruptly being placed on administrative leave.
The state police superintendent said the crisis demanded an urgent response that required a leadership change.
Oliver has an autoimmune disorder that makes her vulnerable to wildfire smoke, so she agreed to evacuate.
She was nervous about going to a shelter because of the virus, but sleeping in a car with her husband, 15-year-daughter, two dogs and a cat was not a viable option.
The temperature checks and social distancing at the American Red Cross shelter helped put her mind at ease.
Now the family waits, hoping their house will survive. She has previously experienced homelessness.
I'm tired. I'm tired of starting all over. Getting everything, working for everything, then losing everything, she said.
Those who still had homes were not safe in them. A half-million Oregonians were under evacuation warnings or orders to leave.
With air contamination levels at historic highs, people stuffed towels under door jambs to keep smoke out. Some even wore N95 masks in their own homes.
Some communities resembled the bombed-out cities of Europe after World War II, with buildings reduced to charred rubble piled atop blackened earth.
Residents either managed to flee as the flames closed in, or perished.
Millicent Catarancuic's body was found near a car on her 5-acre property in Berry Creek, California.
The flames came so quickly she did not have time to get out.
On Tuesday, she packed several of her dogs and cats in the car but later called her daughter to say she decided to stay. Firefighters had made progress battling the blaze.
The wind was calm. The flames still seemed far away. Then they rushed onto the property.
I feel like, maybe when they passed, they had an army of cats and dogs with her to help her through it, said her daughter, Holly Catarancuic.
In Oregon alone, more than 40,000 people have been evacuated and about 500,000 are in different levels of evacuation zones, Gov. Kate Brown said.
Fires along Oregon's Cascade Range grew Saturday, but at a slower rate than earlier in the week, when strong easterly winds acted like a bellows, pushing two large fires the Beachie Creek Fire and the Riverside Fire toward each other and the state's major population centers, including Portland's southeastern suburbs.
Fire managers did get a spot of good news: Higher humidity slowed the flames considerably.
In California, a total of 28 active major fires have burned 4,375 square miles, and 16,000 firefighters are trying to suppress the flames, Cal Fire Assistant Deputy Director Daniel Berlant said. Large wildfires continued to burn in northeastern Washington state too.
In all, 22 people have died in California since wildfires began breaking out across the state in mid-August.
President Donald Trump will visit California on Monday for a briefing on the West Coast fires, the White House announced.
Democratic presidential candidate Joe Biden and the governors of California, Oregon and Washington state all Democrats have said the fires are a consequence of global warming.
We absolutely must act now to avoid a future defined by an unending barrage of tragedies like the one American families are enduring across the West today, Biden said.
The same smoke that painted California skies orange also helped crews corral the state's deadliest blaze of the year by blocking the sun, reducing temperatures and raising humidity, officials said.
Smoke created cooler conditions in Oregon too, but it was also blamed for making the dirtiest air in at least 35 years in some places.
The air quality index reading Saturday morning in Salem, the state capital, was 512.
The scale normally goes from zero to 500.
Above 500 is literally off the charts, said Laura Gleim, a spokesperson for the Oregon Department of Environmental Quality.
Because past air quality was rarely so poor, the government's yardstick for measuring it capped out at 500, Gleim said.
The department started monitoring in 1985.
The weather conditions that led up to the fires and fed the flames were likely a once-in-a-generation event, said Greg Jones, a professor and research climatologist at Linfield University in McMinnville, Oregon.
A large high-pressure area stretching from the desert Southwest to Alaska brought strong winds from the east toward the West Coast, reducing relative humidity to as low as 8 per cent and bringing desert-like conditions, even to the coast, Jones said.
