An air quality alert is in effect until midnight as smoke from wildfires in western states and Canada continues to blow through the region. The smoke also affected air quality in the region last week.

On Friday, the Tennessee Department of Environment and Conservation issued a code orange air quality alert for fine particulate matter, including in the Knoxville metropolitan area. The air quality alert includes Anderson County. It went into effect at midnight Friday and continues until midnight Saturday.

The orange alert means the air is unhealthy for people in sensitive groups, according to AirNow.gov. This includes people with heart or lung disease, older adults, children, and teenagers. They should choose less strenuous activities, like walking instead of running, so they don’t breathe as hard. They should also shorten the amount of time they are active outdoors, and postpone outdoor activities if possible to when the air quality is better. Everyone else can enjoy outdoor activities, AirNow.gov said.

On Thursday, CBS News reported that there are wildfires burning in 13 states, and 83 large fires have burned close to 1.3 million acres. The largest fire, the Bootleg Fire in Oregon, was burning more than 476 square miles, an area about the size of Los Angeles and three times the size of Detroit.

Smoke from the wildfires is blowing into Canada and then south around the Great Lakes and east to the East Coast, according to a map posted by AirNow.gov and shared by the National Weather Service in Morristown.

The air quality forecast for the Knoxville area on Tuesday is again unhealthy for sensitive groups.

The air quality in the Knoxville area at about 8 a.m. Tuesday was unhealthy due to particle pollution, according to AirNow.gov. That means people with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion. Everyone else should reduce prolonged or heavy exertion.

Unhealthy for sensitive groups means the general public is not likely to be affected, but people with lung disease, older adults, and children are at a greater risk from exposure to ozone, while people with heart and lung disease, older adults, and children are at greater risk from the presence of particles in the air.

The poor air quality in the the Knoxville and Chattanooga metropolitan areas, as well as in the Great Smoky Mountains, is due to smoke from wildfires.

“Everyone should limit prolonged outdoor exertion,” the National Weather Service in Morristown said Tuesday. [Read more…]

A smoky haze continues in East Tennessee, and an air quality alert has been issued for much of the Tennessee Valley, including the Knoxville area, because of smoke from wildfires, officials said Monday.

People with heart or lung disease, older adults, and children were advised to avoid prolonged or heavy exertion. Everyone else should reduce prolonged or heavy exertion, according to the forecast on AirNow.gov.

The National Weather Service in Morristown said unhealthy air quality conditions will continue across much of the area today.

“Plumes of smoke from wildfires will continue to linger in the atmosphere across the Tennessee Valley and southern Appalachian Mountains,” the National Weather Service said. “The smoke plumes will reduce visibilities and produce poor air quality conditions.” [Read more…]
