Description:
Conditions are changing rapidly at the moment with frequent wind shifts over the past few days. On Friday we had snow and wind from a North Westerly direction.Since then, a SW flow has developed.Over the next 24 hours, snow showers are due to ease but severe gale SW winds will lash the region. Consequently, areas of wind slab are likely to have formed on a range of aspects above 1600m. Avoid areas such as ridge line entry points and steep,unsupported slopes if you think deposits of stiff wind driven snow are present.Currently,there is plenty of snow available for transport and is important to keep in mind that moderate to strong winds can quickly create avalanche hazard even when skies are clear. If in doubt, remain on low angled terrain.

Recent Avalanche Activity

Recent Avalanche Activity
No avalanches reported during the past 24 hours. However recent storm activity from the W1/2 and long periods of poor visibility have hampered observations especially on and near the Divide.

Current Snowpack Conditions

Current Snowpack Conditions
Cold,dry snow continues to accumulate as the result of ongoing shower activity from the SW. A fall of relatively wet NW snow occurred late last week which appears to have bonded well.Prior to last weeks snowfalls, areas of melt/freeze crust were widespread especially on the solar aspects (East through North to West) . Facetted snow (loose and sugary ) has existed in places both on the surface and in buried layers, especially on cold, shady slopes (South and SE aspects). Below about 1600m, the cover is either very thin or has already disappeared.

Mountain Weather

Mountain Weather
Tuesday - snow showers to low levels easing and severe gale SW winds gusting to 110kph about higher ground. Be prepared to modify your plans if conditions begin to deteriorate rapidly.

Sliding Danger

Slide For Life
Areas of thinly covered melt/freeze crust are currently widespread. As a result, you could take a long, uncontrolled slide if you fall over. Remain alert as to where you would end up if you took a slide and exercise extra caution if the run out is poor. As we shift to more Spring like melt/freeze conditions, it is worth considering adding ski crampons or crampons and an axe to your pack along with plenty of sunscreen.
