* WHAT...For the Freezing Fog Advisory, visibility one quarter mile or less in areas of dense freezing fog. For the Air Stagnation Advisory, light winds and limited air movement will lead to a period of stagnant air conditions. This scenario could result in the build up of air pollutants over time. * WHERE...West Central Willamette Valley. * WHEN...For the Freezing Fog Advisory, until 11 AM PST Tuesday. For the Air Stagnation Advisory, until 4 AM PST Thursday. * IMPACTS...Deteriorating air quality may cause issues for people with respiratory problems. Low visibility in areas of dense freezing fog could make driving conditions hazardous. * ADDITIONAL DETAILS...Frost is possible on elevated surfaces and grassy surfaces, as well as bridges and overpasses.

* WHAT...For the Freezing Fog Advisory, visibility one quarter mile or less in areas of dense freezing fog. For the Air Stagnation Advisory, light winds and limited air movement will lead to a period of stagnant air conditions. This scenario could result in the build up of air pollutants over time. * WHERE...South Willamette Valley, and East Central Willamette Valley. * WHEN...For the Freezing Fog Advisory, until 11 AM PST Tuesday. For the Air Stagnation Advisory, until 4 AM PST Thursday. * IMPACTS...Deteriorating air quality may cause issues for people with respiratory problems. Low visibility in areas of dense freezing fog could make driving conditions hazardous. * ADDITIONAL DETAILS...Dense fog will impact portions of the I-5 corridor from Salem to Eugene. Frost is possible on elevated surfaces and grassy surfaces, as well as bridges and overpasses.
