Areas that experienced recent heavy rain should see the snowpack quickly stabilize as temperatures cool. With that said, new snow that accumulates on this refrozen surface may form unstable new storm slabs before the new snow has a chance to form a solid bond. High alpine areas that haven't seen rain are on a different trajectory. Here, recently formed storm slabs will need more time to stabilize as they experience continued loading from new snow and wind.Looking forward, new snow and wind on Wednesday night is expected to promote a new round of storm slab activity in higher elevation lee terrain.

Heavy rainfall soaked the upper snowpack at most elevations over Sunday night and Monday. High alpine elevations in areas like Sky Pilot and the Chehalis Range may have seen thick new storm slabs develop over the same time period. Below these elevation-dependant surface conditions, storm snow totals from the past week reached 110-180 cm. The crust that exists beneath these recent snow accumulations is likely to have now formed a solid bond to the overlying snow.
