A slight break in precipitation today but more is on the way this evening. Recently formed storm slabs are still reactive to human triggering.
Summary
Weather Forecast
A low pressure system is building off shore and will arrive at Rogers Pass late this evening. Mainly cloudy for today with freezing levels rising to 1500m and light winds from the south. Expect 14cm of snow tonight with the arrival of the storm. Freezing levels climb to 1800m Saturday with another 22cm of snow and SW winds gusting to 75km/h.
Snowpack Summary
Intense precipitation and strong southerly winds have created touchy storm and wind slabs above treeline. Freezing levels have come down creating a breakable surface crust below treeline with moist/ wet snow below. Weak interfaces in the upper snowpack are still easily trigged by human loading. The late Feb crust interface is now down 1-1.5m.
Avalanche Summary
Natural activity subsided yesterday at higher elevations. Below treeline, small loose wet avalanches were observed next to the highway corridor. A field team ski cut a size 1.5 storm slab on a steep SE facing roll at 2000m. Newly formed storm and wind slabs remain reactive and will once again fail naturally with the forecasted precipitation .
