Weather Forecast
Overnight and Sunday: Freezing levels dropping overnight to about 1500 metres combined with moderate Southwest winds and light precipitation. Freezing levels rising up to 2300 metres with moderate Westerly winds during the day. Expect broken skies with sunny periods.Monday: Freezing levels are expected to continue to rise through the night and reach about 2600 metres during the day. Broken skies may result in periods of strong solar radiation to add more warmth to the snowpack.Tuesday: Southwest winds increasing to strong with cloudy skies and moderate to heavy precipitation beginning in the afternoon. Freezing levels remaining at 2600 metres overnight and then lowering slightly during the day.
Avalanche Summary
No new avalanches reported.
Snowpack Summary
Another 5-10 cm of new snow overnight has increased the recent storm slab to 10-30 cm in depth. The new thin storm slab is sitting on a 2-5 cm melt-freeze crust that developed over the past few days on all but shaded North aspects in the alpine. This crust has been reported to be "knife" resistance in some parts of the region and may have a layer of surface hoar below the new storm snow. There is now about 75 cm of well compacted snow above the March 10th melt-freeze crust. In some areas the March 10th crust is helping to bridge over the deeply buried late January/early February persistent weak layer. The Jan/Feb deep persistent weak layer continues to be a concern for very large destructive avalanches. Releases on this layer may be more likely during periods of strong solar radiation and/or prolonged warm temperatures at alpine elevations.
