Anyone planning to drive through mountain passes or hike in elevations above 3,000 feet this weekend should be prepared for snow.

The National Weather Service has issued a winter storm watch for the Cascades because snowfall is expected at higher elevations starting Friday night, Oct. 19. The snow could be heavy at times and is expected to affect mountain passes.

Forecasters say Stevens Pass could get 4 to 8 inches of snow, and it's likely to stick.

Hiking trails also could be covered in snow. Hikers are advised to prepare for winter conditions or shift their plans to lower elevations.

The road to Artist Point has been closed since Tuesday, Oct. 16, because of expected snow. It won't reopen until summer 2013.
