The hazard may go higher than forecast if precipitation amounts are greater than expected. If you have field observations to share
here, we'd love to hear from you.

Weather Forecast
The cold front has passed through the area leaving cool unsettled conditions. Expect convective showers over the next few days.SUNDAY: A cool unstable air mass will continue to bring precipitation to the region overnight Saturday and Sunday. 10 to 15cm of precipitation, freezing level around 110 m and winds moderate to strong from the South West.MONDAY: Cloudy with flurries and/or rain. Freezing level will rise to 1600m and moderate to strong winds from the South West.TUESDAY: A brief break in the weather pattern. Cloudy with sunny periods, freezing level around 1200m, winds light to moderate from the South West.
Avalanche Summary
No reports of avalanche activity from yesterday. This is most likely as a result of few field observations. We expect wind slab activity with new loading and strong winds. Solar aspect may become active again when the sun come out.
Snowpack Summary
20 to 30cm of storm snow now rests on a variety of crusts and old surfaces including surface hoar and facets that formed in sheltered locations during the recent clear weather. Moderate to strong south west winds are redistributing the storm snow into wind slabs on the lee sides of ridge tops. A facet/crust layer that was buried in mid-March is now approximately 50-100 cm down. This remains a concern in the region because of it's potential for very large avalanches. Cornices are now large and mature and may collapse with increased loading, possibly triggering the deeply buried weak layer.
