Dozens of forest fires in the United States west and Canada, led by major fire in Oregon, send smoke to the east, deteriorating air quality and causing colorful sunsets in several places.

But because of the flow of jets and other cross-continental air currents, regional disasters are being felt nationally.
Wildfire preparations encouraged advisors from the authority of the health and environment of New York on Tuesday to fine particle problems as the area air quality index reached 118, which was unhealthy for sensitive groups such as people with respiratory problems.
Aqi readings above 100 are also recorded in other northeastern cities, including Boston, Hartford and Philadelphia.

“Sunset looks prettier, redder, more colorful.” Said National Weather Meteorology Expert Bob Orevec from the weather prediction center at College Park, Maryland.
While some smoke diffuses into the upper atmosphere after traveling thousands of miles, they can still reduce air quality, said Nauslar.
The unhealthy AQI reading was recorded on Monday the Idaho and Montana section, which, along with the smoke state driven by the wind from the South Oregon Bootleg fire, according to the Margaret Key air resource advisor.
“Wildfire smoke exposure also increases susceptibility to respiratory infections including Covid, increases the severity of such infections, and makes recovery more difficult,” keyword via email.
The Bootleg fire, had the largest fire in the country, grew with 24,200 hectares last night to almost 388,600 hectares (157,260 hectares), about half of the size of Rhode Island.

The increasing smoke from the fire raged inside and around the Fremont-Winema National Forest of around 250 miles (400 km) South Portland has produced at least two pyrocumulonbus clouds, unusual phenomena often called fire clouds, Nifc Nifc said.
“It can begin to produce his own lightning, and basically become a lightning storm produced,” he said by telephone.
This can cause rapid and uncertain fire spread.
