The sun is packing a strong punch these days. When it does make an appearance, expect the snow to become unstable. High North aspects still have good skiing.

Weather Forecast
The spring weather pattern continues for another day. Starting Monday the temperatures will take a dramatic turn to the warmer side. Until then we'll see freezing levels hover around 1600m, and convective weather moving through areas near the divide. Snow accumulations will be negligible. The winds will continue with a strong pulse tonight in the alpine.

Snowpack Summary
Today's field trip took us to a notoriously thin snowpack area on the east side of the Smith Dorrien Road.. The HS varied from 20-50cm's. At treeline, we found the bottom layers to be very weak and consisted mostly of depth hoar and facets. Above that base layer sits a slab that has lost most of its structure from the freeze/thaw cycles. No whumphing or cracking was observed. The day time warming has begun to stabilize all aspects up to 2100m. Any slope that has seen the sun now has a 1-2cm sun crust on top. In other areas in the park, the Feb 10 is down 120-140cm's at treeline with hard shears. The recent winds have created windslabs in open areas at treeline and above. These are not reactive at the moment and expected to bond quickly to the underlying layers. Generally lots of snow settlement in all areas.
