SALEM, Ore. _ People in central and northeast Oregon, including in Eugene, Portland and Salem, continued to face hazardous air quality Sunday.
The Oregon Department of Environmental Quality reported Air Quality Index numbers that were off the chart.
Air Quality Index is considered hazardous between 301 and 500. Portland's index is currently at 426.
Values above 500 -- which two cities, Madras and Roseburg both reported having -- are beyond the index's scale.
Officials advised people to stay indoors and that the low visibility, caused by fog and smoke, is creating hazardous driving conditions.
In Salem, where the Air Quality Index is 394, a dense smokey haze that clouded roads and homes made it difficult to see further than 50 yards ahead.
The National Weather Service in Portland reported that rain is expected Monday night, which could help clear smoke in Oregon next week.
