Problem Details

Are you ready for winter? A few tips to get you and your riding buddies ready to shred:
  • Replace the batteries in your avalanche beacon. Check your avalanche probe for wear or breaks in the cable. Check your avalanche shovel, do you have both the shaft and blade in working order?
  • Plan a fun avalanche rescue practice with your riding partners. Is everyone on the same page for a fast, efficient rescue?
  • Is there a fresh, charged cartridge in your avalanche airbag pack? Go ahead and give it a test pull - does it deploy properly?
  • Fitness - reduce the possibility of injury on your first ride/outing - start now by improving your flexibility, strength, and cardio.
  • Check your skis and snowboards: missing binding screws? burrs on your edges? need wax?
  • Check your snowmachine oil, plugs, belt, brakes, and headlight.
The snow will be here soon... While you're waiting, check out Valdez Avalanche Center's contribution to avalanche safety with our collaboration on testing a model for avalanche flow, presented this week at the International Snow Science Workshop in Innsbruck, Austria.   Forecasts will begin December 1 for the 2018-2019 season. Forecasts will be published Friday, Saturday, and Sunday mornings. Observations will be accepted throughout the season. If you get out early season, post a pic and description of what you see. Here's to an awesome winter!!
