There is a special avalanche warning in effect for our area.
Rising freezing levels and solar radiation may trigger another large avalanche cycle this weekend.
Minimize your exposure to overhead avalanche terrain.
Up to 35cm of new snow, combined with warm temps and strong gusty winds are building fresh wind slab. These may bury surface hoar or a preserved stellar layer and may be sensitive to human triggering.
This layer has been recently active and in some instances has been enough to step down to the deeper Dec 1 curst/facet layer. Investigate the snowpack before committing to your line.
The Dec 1 crust/facet layer woke up last Monday, resulting in numerous very large avalanches This is now a low probability / high consequence avalanche problem. It will be stubborn to trigger, but if it goes the results will be very large.
Battle of the Weather Models continue, as they can't seem to agree on freezing levels. Sunday will see a mix of sun and cloud with a freezing level up to 2300m (highest forecasted elevation) and an alpine high of -2. Winds will be from the West, 25-60km/hr. Freezing level will drop back down to valley bottom on Monday. No new snow in the forecast.
Up to 35cm of recent snow now buries the Jan 20th (2-4mm) surface hoar. The Jan 11 (2-5mm) surface hoar is down ~70-90cm. The Dec 1 crust/facet combo is down ~1.5 - 2.5m. This layer came alive last storm and will be a lingering concern. Wind and warming temps will promote the formation of wind slabs along ridge lines and cross loaded features.
Helicopter Avalanche Control on Saturday, just West of the Park produced several size 4 avalanches.
A natural avalanche cycle occurred on Thursday with a notable size 4 off of Ross Peak that ran into the Elephants Trunk in Loop Brook.
A widespread natural and artillery avalanche cycle occurred last Monday up to size 4, with some crowns over 2m deep.
