Stick to simple or non-avalanche terrain while the storm snow settles and stabilizes.
Avoid overhead hazard especially during periods of sun.
A persistent weak layer of surface hoar or facets is buried 80 to 150 cm. This layer remains a concern on upper-elevation northerly through easterly slopes.
Up to 60 cm of recent snow has formed widespread storm slabs that need a few days to bond. The new snow will be especially reactive on wind-loaded slopes and on sunny slopes during periods of solar radiation.
Over the last three days, explosive control in the Lizard Range has produced numerous storm slabs up to size 2 (large). Last Thursday, a widespread natural cycle was observed in the Lizard Range with storm slabs up to size 2.5, and explosive control also produced numerous small storm slabs.
Up to 60 cm of recent snow has built widespread storm slabs in the region, with another 5 to 15 expected overnight Sunday. Due to southwesterly winds, slabs are expected to be especially reactive on lee north through east facing slopes near ridgetops. In most areas, the storm snow rests on a melt-freeze crust, except for high elevation north and east facing slopes.
A persistent weak layer of surface hoar or facets from late January is buried 100 to 150 cm. This layer triggered large avalanches earlier in March. The greatest concern for this weak layer is on upper-elevation northerly and easterly slopes. The lower snowpack is generally well-settled and strong.
