Additional Information
AVALANCHE HAZARD TREND
NWS is forecasting cool temps, no new snow and light winds today and overnight. This kind of mediocre Alaska weather will not increase the avalanche hazard today.
Instability will increase with any new, rapid load, such as precipitation and/or wind loading. Keep a close eye on the weather, as our current snowpack only needs a little extra load to increase the avalanche hazard again.
Alerts
Moderate avalanche hazard does NOT equal safe conditions everywhere. Deciphering the avalanche puzzle will be complex, with large, human triggered avalanches possible on a multitude of weak layers in the snowpack. Help us give the gift of NO avalanches for Christmas! If you choose to enter avalanche terrain, choose terrain lacking terrain traps.
