Wildfires are raging across Oregon. While officials are concerned with containing the fires, they warn that smoky air can be dangerous for some people.
Most wildfires are in south and central Oregon, increasing the risk of respiratory problems in those areas.
Small particles in smoky air can be harmful for people with sensitivities - older adults, young children and those with heart and lung diseases.
Frank Messina is an inspector with the Department of Environmental Quality. He says that air quality predictions depend on winds and rising temperatures.
"The winds are changing quite often. More and more fires are developing due to the hot conditions. We're going to have some really strong winds out of the north which could potentially cause more problems for the firefighters and more smoke into some of our communities," Messina said.
Messina encourages people not to go out and exert themselves in smoky conditions.
