Weather Forecast
Another clear day for tomorrow. Our forecasts are saying there will be a drastic change in freezing level. We are expecting it to rise to 2600m tomorrow afternoon. The winds will be mostly calm with the odd gust to 30km/hr. This warm spell is expected to stick around for awhile yet. The models suggest it will persist until Sunday night. After that it will stay clear, but cool off significantly.
Avalanche Summary
Nothing new.
Snowpack Summary
The calm, cold, clear nights have promoted the growth of a new surface hoar layer. With the long clear spell ahead of us, this will continue to grow. Surface facetting has also become more noticeable in the last few days as well. Other than that the snowpack has seen little change, except for some settlement. Snow depth at Burstall parking lot is 65cm, Burstall Pass is 80cm and Highwood Pass is 64cm.
Problems
Wind Slabs
These slabs will linger for some time yet. Steep unsupported pockets remain the concern. With the predicted rise in freezing level, there is a chance the reactivity will increase on steep solar aspects.
Avoid cross loaded features.>Avoid unsupported slopes.>
