Freezing Fog Advisory issued December 3 at 5:08PM PST until December 4 at 12:00PM PST by NWS Portland OR
* WHAT...For the Freezing Fog Advisory, areas of fog and freezing
fog, with visibility one quarter mile or less. For the Air
Stagnation Advisory, poor air quality will continue. This is due
to an inversion and stagnant air conditions near the surface that
will continue to trap pollutants.
* WHERE...Central and Southern Willamette Valley.
* WHEN...For the Freezing Fog Advisory, until noon PST Wednesday.
For the Air Stagnation Advisory, until 4 AM PST Thursday.
* IMPACTS...Poor air quality may cause issues for people with
respiratory problems. Fog will be reforming this evening. Low
visibility could make driving conditions hazardous. With freezing
temperatures, moisture in the fog could freeze on bridges and
overpasses, making slick and icy spots.
