Weather Forecast
Weather models have all come to an agreement, it's still winter. As such, predictions of upwards of 15-25cms are expected in the forecast region starting tuesday afternoon and into the weekend. This is accompanied by transport speed winds (20+ kph). Only time will tell but this could significantly overload the snowpack.
Snowpack Summary
So much will depend on the forecasted snow coming Tuesday evening. Any new snow will be sitting and/or transported onto weak sandwiched wind slab layers on the top 25 cms of the existing snowpack. These are moderately reactive on a already weaken, faceted snowpack at exposed tree line and alpine features.
