Weather Forecast
Flurries today, with the freezing level near 1000m for the high today. Wind at ridge tops will remain strong from the SW. SUNDAY: Cloudy with flurries, freezing levels between 500 and 1000m, winds moderate to strong from the South WestMONDAY: Much the same as the previous two days, cloudy with flurries, wind from the South, and the freezing level may climb to 1500m during the day.TUESDAY: A break in the weather, cloudy with some sunny periods, light flurries, freezing level around 1000m, wind from the SW.
Avalanche Summary
No reports of natural avalanche activity yesterday, most likely because of few observations during this storm, but one operator has reported good results, up to size 2.5, with explosives in wind loaded terrain.
Snowpack Summary
Moderate to strong winds are scouring exposed alpine slopes and loading lee features. In some parts of the region, surface hoar and facetting occurred on protected, high, north facing alpine and treeline slopes during the last spell of clear weather. These facets may now be getting buried with the new snow and wind loading. A crust with surface hoar buried on March 25th is still considered a potential problem in parts of the forecast region but has only been reactive recently in the north part of the region. This may come back to life with the new snow and wind loading. Cornices are now large and may collapse with increased load from the storm.
