 AN AIR STAGNATION ADVISORY REMAINS IN EFFECT UNTIL 4 PM PST
 TUESDAY. A DENSE FOG ADVISORY REMAINS IN EFFECT UNTIL NOON PST
 TODAY. 
 
 DENSE FOG WILL CONTINUE TO CAUSE PROBLEMS FOR MOTORISTS THROUGH
 SATURDAY MORNING. VISIBILITIES WILL BE A QUARTER MILE OR LESS OVER
 THE WATERVILLE PLATEAU...PORTIONS OF THE WASHINGTON
 PALOUSE...PARTS OF THE WEST PLAINS...AND OVER NORTHERN PARTS OF
 THE UPPER COLUMBIA BASIN. MOTORISTS TRAVELING ON HIGHWAY 2 FROM

 REDUCED TO LESS THAN ONE QUARTER MILE. IF DRIVING...SLOW DOWN...
 USE YOUR HEADLIGHTS...AND LEAVE PLENTY OF DISTANCE AHEAD OF YOU.
 IN ADDITION...TEMPERATURES ARE EXPECTED TO REMAIN BELOW FREEZING.

 HAZARDOUS. THIS WILL BE ESPECIALLY TRUE FOR BRIDGES AND
 OVERPASSES. MOTORISTS AND PEDESTRIANS SHOULD USE CAUTION.
 
 STRONG HIGH PRESSURE AT THE SURFACE AND ALOFT WILL REMAIN OVER
 THE INLAND NORTHWEST THROUGH EARLY NEXT WEEK. LIGHT WINDS AND A
 STRONG LOW LEVEL INVERSION WILL CONTRIBUTE TO THE POTENTIAL FOR
 POLLUTANTS...LIKE SMOKE AND VEHICLE EXHAUST...TO BE TRAPPED IN
 THE LOW LEVELS OF THE ATMOSPHERE.
 
 AN AIR STAGNATION ADVISORY INDICATES THAT DUE TO LIMITED MOVEMENT
 OF AN AIRMASS ACROSS THE ADVISORY AREA...POLLUTION WILL INCREASE

 SHOULD FOLLOW THEIR PHYSICIANS ADVICE FOR DEALING WITH HIGH
 LEVELS OF AIR POLLUTION.
