This week may be especially dangerous on local roads and mountain passes.
snow and wind is expected every day this week - with another big system coming in on Wednesday.
Peter Murphy with the Oregon Department of Transportation talks about the challenge of driving in these conditions.
"THE WIND IS A CHALLENGE IN ITSELF- BECAUSE WE'RE GETTING BLIZZARD-LIKE CONDITIONS....BLOWING SNOW -LIGHT- A LOT OF WIND AND THE SNOW THAT COMES WITH IT ACROSS THE HIGHWAY MAKES FOR VERY LOW VISIBILITY - GO SLOW- CAUTION- TAKE THEIR TIME AND LEAVE PLENTY OF SPACE BETWEEN YOU AND GUY IN FRONT OF YOU - AND THERE'S A BIG CHANCE FOR PEOPLE TO COME UP ON SOMEONE THEY DIDN'T EXPECT WITHOUT THEM BEING ABLE TO SEE VERY FAR IN THE DISTANCE."
Murphy was up on Mount Bachelor and saw the dangerous conditions first hand on Monday morning. He says it was very dramatic with tons of snow, lots of wind and very poor visibility. He said you could only see about 20 feet in front of you. Murphy says when conditions are that bad it's best to just avoid driving on mountain passes if possible.
The National Weather Service in Pendleton says another big system with wind and snow could move into the area on Wednesday and continue on for a few hours into Thursday. Later Thursday and Friday will be more mild, but a change of snow showers are still in the forecast.
