Description:
With heavy snow and strong winds in the forecast the avalanche danger will increase. Slopes lee to the North Westerly half above 2000m will see rapid growth of windslabs. These new slabs will be sitting on a slick icy surface so there is a good chance that they won't bond well to it. Human triggering may become likely, so avoid all areas of fresh loading. Keep in mind that the conditions will change quickly, so just because there wasn't much snow on your way up, it doesn't mean that you won't encounter problems by the time you start coming back down. Currently there is not enough snow on the ground below 2000m to be of concern, but this will most likely change over the next 24 hours.

Current Snowpack Conditions

Current Snowpack Conditions
The snowpack is currently strong and stable, consisting of well consolidated melt forms with strong ice layers in between. As of Monday afternoon new snow has just started to fall above 1700m. No significant amounts have accumulated, but it looks like the snow will continue and become heavier over night and into Tuesday morning, so you can expect windslabs to form.

Mountain Weather

Mountain Weather
Expect heavy snowfall for Monday night and into Tuesday. The snow level will be somewhere around the 1400-1600m mark. Winds will increase to gale North West / Westerlies.
