The National Weather Service issued an air stagnation advisory at 1:33 p.m. on Thursday in effect until Friday at 4 a.m. for Oregon Lower Treasure Valley as well as Harney, Baker and Malheur counties.
The weather service says to be ready for, “An extended period of stagnant air, with light winds and little vertical mixing. This is due to an inversion near the surface that will continue to trap pollutants.”
“Poor air quality may cause issues for people with respiratory problems,” says the weather service. “Persons with respiratory illness should follow their physicians advice for dealing with high levels of air pollution during periods of stagnant air.”
Advance Local Weather Alerts is a service provided by United Robots, which uses machine learning to compile the latest data from the National Weather Service.
