Good skiing can be found at higher elevations where the temperatures and sun have not damaged it. There will be a definite change in snow quality as you ski in to lower elevations.
Summary

Moderate -
Weather Forecast
Monday will bring cloudy sky's and trace amounts of snow. Day time highs around -6. Winds should be light out of the SW. Freezing levels are slowly rising though the beginning of the week to 2200m. Keep tabs on how the snow changes underfoot while traveling through he terrain.
Avalanche Summary
1 size 2 wind slab avalanche on a N-NE aspects in the alpine was observed today. The crown looked to be from 24-48 hours ago. No other observations
Snowpack Summary
Saturday night brought 15cm snow to the spray. The temps stayed cool (-3) up high at Burstall pass (2300m) where the snow remained dry. Down in the valley we got above Zero degree's which will have made the surface snow moist and now created a Temperature crust up to 2000m as the night cools. This is the normal fluctuation for the duration of the season. Continue to monitor the bond to the Feb 19th layer down 40-70cm.Â
Solar aspects will have a variety of sun crusts of varying thickness depending on the days solar input.
Terrain and Travel
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
- Be alert to conditions that change with elevation and wind exposure.
- Wind slabs may be poorly bonded to the underlying crust.
- Cornices become weak with daytime heating or solar exposure.
Problems
Wind Slabs
Recent winds have created windslabs in alpine areas. The slabs are more specific at treeline and below. Watch for areas where recent slabs are overlying a suncrust that can act as a perfect bed surface.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
Carefully evaluate the bond with the early March and Feb 19th crusts down 40 and 70cm. Recent wind loading will make this problem more reactive, as will periods of intense solar input.
Aspects: South East, South, South West, West.
Elevations: Alpine, Treeline.
