Avalanche Hazards Heavy snowfall in the mountains, followed by rain, is a combination that can lead to avalanche hazards, reports the Washington State Department of Transportation. Maintenance crews will work to keep the highway clear of snow, and they may set off controlled avalanches to direct when and where the snow falls. The exact times for avalanche control work cannot be predicted, because they change with the weather conditions, but when possible it will be done in off-peak times. During avalanche control work, the passes must be closed to traffic for safety. Amtrak trains operate reliably on regular schedules, even in severe winter weather.
Transit systems are also well-prepared for snow and ice.
Stay tuned to local radio and television traffic reports or call your local transit agency for more information. Reservations are required on Amtrak trains, but seats are usually available at the last minute. Wear appropriate shoes. Walkways at bus stops and train platforms can be slippery. Remember, you won't be the only one looking for a better way to travel - expect more riders than usual and give yourself extra time to get to the bus stop or train station.
