At 1:33 p.m. on Thursday, the NWS issued an air stagnation alert for the Lower Treasure Valley of Oregon, as well as the counties of Harney, Baker, and Malheur, that would last until 4 a.m. on Friday.
“A prolonged period of stagnant air, with light winds and little vertical mixing,” the weather agency warns. This is because pollutants will continue to be trapped by an inversion close to the surface.
According to the weather service, “people with respiratory problems may experience problems due to poor air quality.” “Persons with respiratory illness should follow their physicians advice for dealing with high levels of air pollution during periods of stagnant air.”
United Robots offers a service called Advance Local Weather Alerts that gathers the most recent information from the National Weather Service using machine learning.
