Moderate - Forecast snowfall amounts are uncertain on Wednesday
The region will see a fairly unsettled weather pattern through the forecast period. Convective spring-like conditions could bring pulses of new snow in some areas or none in others. TUESDAY NIGHT: Light snow amounts 3-10 cm at upper elevations and freezing levels 1300 m. Ridgetop winds light from the NE.WEDNESDAY: Cloudy with some sunny periods and light snow 3-8 cm. Alpine temperatures near 3 degrees and freezing levels 1900 m. Ridgetop winds 10-30 km/h from the southwest.THURSDAY: Cloudy with some sunny periods and a trace of snow. Alpine temperatures near 0 degrees and freezing levels 1300 m. Ridgetop winds light from the southwest.FRIDAY: A mix of sun and cloud. Alpine temperatures near 3 degrees and freezing levels rising to 2100 m. Ridgetop winds light with strong SW gusts.
On Tuesday no new avalanches were reported. On Monday there was a natural loose wet avalanche cycle to size 1.5 on solar aspects as the new snow ran on the crust. Snowfall amounts are uncertain for the next 24 hours. Storm slabs may only be an avalanche problem with new snow and loading.With spring conditions, the avalanche hazard will fluctuate greatly depending on the strength of the overnight re-freeze and how quickly the snowpack is warmed up.
Sunday night the region picked up 10 cm of moist snow which has turned to shmoo from daily warming. This snow rests on a supportive crust above about 1400 m. Below 1400 m the snowpack is becoming isothermal. During the heat of the day, especially under direct sun, the snow surface becomes moist or wet almost everywhere. The exception being high elevation north facing features. Steep, north facing, alpine terrain may still hold a cold, dry, snowpack where a well settled slab rests on weak facets (sugary snow). Although unlikely, human triggering of persistent slabs on this layer may still be possible, especially in rocky alpine terrain with a shallow or highly variable depth snowpack.
