THURSDAY NIGHT: Another 5-10 cm of new snow with freezing level dropping to 1000 m.FRIDAY: Cloudy with sunny periods, moderate southwest winds, freezing level up to 1500 m.SATURDAY: Cloudy with scattered flurries and up to 5 cm of new snow later in the day, moderate southwest winds, freezing level around 1300 m.SUNDAY: Cloudy with isolated flurries, strong southwest winds, freezing level around 1300 m.

Widespread storm slab activity was reported on Thursday. This included several explosive and naturally triggered size 2 avalanches in the Lizard range. Ski cutting also produced size 1 wet slabs in rain saturated snow at below treeline elevations. Looking ahead to Friday, natural storm slab activity should taper off but human triggering will remain likely at higher elevations.

The region received 30-40 mm of precipitation on Thursday, which fell as rain in the valleys and as snow above 1500 m. The new snow should settle into a reactive storm slab at higher elevations. Beneath the new snow, you'll find a mix of hard old wind slabs, melt-freeze crusts and moist snow from the recent warm spell. Some weaknesses may still exist within the 90 cm of storm snow from last week; however, recent warming has likely helped strengthen these layers. The mid and lower snowpack are generally well settled and stable but isolated basal weaknesses may exist in shallow snowpack areas.
