The National Weather Service (NWS) issued a winter weather advisory for Stevens and Snoqualmie passes through Saturday afternoon. Snow levels will drop to 3,500 feet with up to 10 inches of snow expected. The snow is expected to turn into a rain mix after 4 p.m., resulting in slushy road conditions.

Early Sunday, the winter storm warning goes into effect at 4 a.m. until 10 a.m. Monday. Snow levels will drop to 3,000 feet, with an additional 6 inches and heavy snowfall at times.

In addition to Stevens and Snoqualmie passes, winter storm watches and weather reports also cover the western slopes of the North Central Cascades and the western slopes of the South Central Cascades. Towns include Paradise, Darrington, Morton, Ashford, Longmire, Skykomish, Crystal Mountain Ski Area, Index, Packwood, Randle and Baring.

“We are already anticipating a new possible storm or similar storm-like conditions potentially brewing as early as next Sunday,” Scott Klepach, a spokesman for the Washington State Department of Transportation (WSDOT), told KIRO 7.

Klepach suggested that travelers should seriously consider how urgently they need to cross the mountains early next week.

“If you’re unsure, stay home and postpone your trip if possible.” According to KIRO 7, Klebach said, “I know this isn’t the most popular statement, but it can really help clear the way. “

Important tips for winter drivers

WSDOT’s Klebach added that travelers should make sure they have the proper tires and chains and the knowledge to put on the chains.

“We can’t stop the rain. We can’t stop the snow, but we can do our best to make sure the roads are as clear as possible,” Klebach said, KIRO 7 reported. “You know, drivers and travelers can help us too by really are attentive.”

Unless drivers have four-wheel drive and snow tires, chains should be placed on the vehicle’s wheels when signs require it. Studded tires do not meet chain requirements in Washington State. There are alternatives to chains that are sometimes easier to use, such as an AutoSock.

The NWS warns that travel during the winter storm watch could be very difficult or impossible at times. Drivers are strongly advised to pack an emergency kit in case of unexpected closures or delays.

Items to consider: Blankets, water, snacks, hats, gloves and phone chargers. For added safety, consider using flares, filling up your gas tank, or fully charging your car battery, and don’t forget chains.
