For the Freezing Fog Advisory, the Rogue, Applegate, and Illinois valleys in Jackson and Josephine counties. * WHEN...For the Air Stagnation Advisory, until 10 AM PST Sunday. For the Freezing Fog Advisory, from 2 AM to 9 AM PST Sunday. * IMPACTS...Poor air quality may cause issues for people with respiratory problems. Most outdoor burning will likely be prohibited as poor ventilation continues. Low visibility could make driving conditions hazardous. Locally slick conditions are possible. * ADDITIONAL DETAILS...A strong area of high pressure remains in place. This will lead to poor mixing of the atmosphere and the trapping of pollutants. The high weakens slightly on Sunday and is likely to strengthen again early next week.
Persons with respiratory illness should follow their physicians advice for dealing with high levels of air pollution during periods of stagnant air. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.
