An Avalanche Watch is being issued for the following zones:
Aspen
Gunnison
North San Juan
South San Juan
A potentially strong storm will dig into the Great Basin tonight and the potential for periods of heavy snow and moderate winds develop early Sunday morning and continue into Monday morning. The four zones in the watch area have a weak underlying snowpack and if  new snowfall amounts verify a natural avalanche cycle is expected by Sunday afternoon. Some of these avalanches could be large and potentially dangerous. Backcountry travelers should expect an increasing avalanche danger Sunday.
We will evaluate the storm again early Sunday morning and an Avalanche Warning may be issued by 6 am if the storm continues to develop as forecast.
