The National Weather Service has expanded its original winter weather information on Tuesday to include the Tri-Cities and most of Eastern Washington.
Roads may be icy as snow and freezing rain are expected across the region.
Up to a tenth of an inch of ice could accumulate in some areas, according to the weather service.
Snow is possible in the Tri-Cities and freezing rain is forecast from 10:00 a.m. to 1:00 p.m. Tuesday, then a chance of rain, snow, and sleet later in the day.
Little or no snow is expected in the Tri-Cities, according to the weather service.
The winter weather advisory for the Tri-Cities area will begin at 10 a.m., and precipitation will change to fog in places. It will end on Tuesday at 10 p.m.
The weather service says freezing rain, possibly mixed with snow, is also forecast Tuesday at Snoqualmie Pass on Interstate 90; from Ellensburg to the Tri-Cities on Interstate 82; and from Ritzville to the Tri-Cities on Highway 395.
People planning to travel should check the forecast and travel conditions before leaving, the weather service says.

“Please use caution, plan ahead and drive according to conditions,” the Washington State Department of Transportation posted on social media. This means slower speeds, slower acceleration, more space between vehicles and allowing extra time and space to stop.
