Weakening snowpack due to rain - Heed fresh snowdrift accumulations at high altitudes
Avalanche danger is low, rising slightly during the day. At high altitudes isolated small fresh snowdrift accumulations are being generated. They can be easily triggered. Danger zones are found esp. in steep ridgeline terrain. The risks of taking a fall outweigh those of being buried in snow masses. In areas with rain impact, moist slides can be increasingly expected.
The snowpack is largely stable. At high altitudes small fresh snowdrift accumulations have been generated by westerly winds, on shady slopes they are poorly bonded with the old snowpack surface. Light rainfall up to 2000 m will moisten the snowpack surface. At low and intermediate altitudes the surface in early morning is melt-freeze encrusted and then softens during the daytime hours due to light rainfall and higher temperatures.
Rain and snow showers will extend into the afternoon, though slackening off. Snowfall level at 1500-1800m, thereafter clouds will begin to disperse, visibility improve, it will become sunny. At 2000m: +1 degree; strong to stormy westerly winds, later easing.
Friday will bring more serene conditions. Avalanche danger levels could increase due to fresh snow and wind.
