Weather Forecast

The high pressure system over our area will persist until late Sunday.  This will mean mostly clear skies, light winds and warming temperatures through the weekend.  By Monday, clouds will increase and we may see some light precipitation as a low pressure system makes landfall on the south Coast.

Snowpack Summary

Up to 15cm of low density new snow overlies: a supportive crust down 10cm below treeline, thick cohesive old storm slabs at treeline and in the alpine, and bare ground many areas in the east. The mid and lower snowpack is generally well consolidated, the mid pack is a series of strong crusts into the alpine on solar aspects.

Avalanche Summary

Numerous small loose snow avalanches occurred during Thursday's snowfall, and as a result of Friday's rapidly warming temperatures.

Confidence

Due to the number of field observations
