OLYMPIA – With more snow, ice and wind in the forecast, the Washington State Department of Transportation is advising drivers to prepare for winter driving conditions across the state.

Forecasters say the snow will start in Whatcom County late today, moving south and east by Wednesday afternoon. Wednesday Puget Sound evening commuters will see snow and ice.

DOT is watching weather forecasts and crews are out night and day patrolling roads, treating highways and plowing snow. To prepare for this next round of winter weather, DOT has serviced the trucks and replenished its stockpiles of de-icer, salt and sand.

Most of the state should be below freezing through the Christmas holiday, with heavy snow and winds in the mountain passes and throughout Eastern Washington.

Drivers should be prepared for roadway ice, know their vehicle, drive for conditions, carry chains, slow down and give yourself extra time to reach your destination safely. Slow down when approaching intersections, off-ramps, bridges or shady spots. These all have potential to develop black ice that makes driving hazardous.
