Low Alpine: Below 1000m
Description:
The avalanche danger for wind slab is MODERATE above 2000m. Snow is forecast to fall lower than this however the paths below 2000m do not have enough snow to be a hazard at this time. The slab will build during the evening and into tomorrow and it is expected loading will mostly be on east facing slopes. The current snow surface will lock up overnight and become a potential sliding layer for the new snow to sit on. I would suggest avoiding convex shaped rolls and pockets of newly wind transported snow.

Current Snowpack Conditions

Current Snowpack Conditions
The snow pack is strong and stable. Spring conditions dominate the region with a strong supportable melt freeze crust capping the snow surface. This crust is breaking down during the day through solar warming and re freezing during the night. The pack is isothermal (rotten) below 2000m.

Mountain Weather

Mountain Weather
A front is forecast to move over the region. Strong westerly winds moving to south easterlies during the afternoon tomorrow (24/10/14). Snow is expected to fall to 1100m with a clearing trend into the evening.
