Weather Forecast

Tuesday's forecast appears to be the beginning of the steady cooling tread that is expected to continue over the rest of the week. Increased clouds and strong high elevation SW winds expected at ridge top with light snow flurries Wednesday. Maybe not a enough to get too excited about but perhaps a little dust on crust? 

Snowpack Summary

Expect a new sun crust on steeper solar aspects up to 2300m with Mondays warm blast of sun. A mixture of rounded and facetted layers are sandwiched between upper layers and the weak depth hoar/ facets prevalent in the lower snowpack down to ground.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Due to the number of field observations on Tuesday
