On Tuesday at 1:49 a.m. an updated winter weather advisory was issued by the NWS Pendleton OR in effect until 8 a.m. for Upper Slopes of the Eastern Washington Cascades Crest.

"Additional snow accumulations up to one inch," can be expected according to the NWS. "A strong winter storm will bring heavy mountain snow tonight through Friday morning. There is a lull expected which will occur late Wednesday morning through early Thursday morning as snow levels rise, bringing a wintery mix or rain before decreasing Thursday and heavy snow returning to the passes."

"Significant snowfall with periods of heavy snowfall rates will combine with low visibility to create difficult driving conditions," comments the NWS. "Persons should consider delaying all travel. If travel is absolutely necessary, drive with extreme caution. Consider taking a winter storm kit along with you, including such items as tire chains, booster cables, flashlight, shovel, blankets and extra clothing. Also take water, a first aid kit, and anything else that would help you survive in case you become stranded. Do not touch downed lines and report any power outages to your electric company. Travel is highly discouraged due to slick roadways and the possibility of downed trees and power lines. Slow down and use caution while traveling."

This advisory is in effect until 8 a.m.

Winter weather driving tips from the NWS

On average, weather-related vehicle crashes kill more than 6,000 people nationwide and injure more than 480,000 people each year. Slow down to stay safe if you must travel during periods of snow or freezing rain. If the temperature outside is near freezing, it is safest to assume ice is present on roadways and drive accordingly. If there is ice on power lines or tree branches, the weight may cause them to snap and fall. Avoid driving during those conditions if possible. If you must go out, choose a route with the least number of trees and power lines. Never touch a downed power line, and call 911 if you encounter one. Here are some additional winter weather driving tips:

• If you must travel out of town, and dangerous winter weather conditions are expected, be sure to tell your family or friends where you are going, your intended route, and the time of arrival.
• Make sure your gas tank is full. Carry a windshield scraper, jumper cables, a small shovel, flashlight, cell phone, blanket and additional warm clothing, drinking water, and high-calorie non-perishable food.
• Don't panic if you become stranded. Call someone to let them know you are stranded. Do not try to walk to safety. Attach a cloth to your car antenna or mirror to indicate you need help. Use the dome light and flashers to make your vehicle more noticeable.
• Be alert for snow plows, and allow plenty of room for them to pass. If you are going around a plow, only do so when you can see the road ahead of the plow.
• Check road conditions before you depart.
