If you venture into the backcountry over the next few days, be careful out there. Given the wintry conditions, including rapidly changing temperatures and fresh snowfall avalanche risk is high. The avalanche danger extends through the coming weekend and will probably continue into next week.
For details see http://www.nwac.us/ or call the Northwest Weather and Avalanche Center at 206-526-6677 (for Washington) and for Mount Hood call 503-808-2400.
Have fun, be safe.
