Starting Tuesday night at 6pm, Tioga Pass and Glacier Point Roads will be shut down to all traffic.
Roads will re-open once weather and road conditions clear up. Park officials say a series of winter storms are expected to pass through the Yosemite Area this week -- through the Thanksgiving holiday weekend.
If you are planning to travel there, you are asked to use Highway 120 West, Highway 140, and Highway 41, which are open year-round.
