In sintesi

These storms are coming in warm... and then cooling off. Wet-loose could be a problem at lower elevations Tuesday through Wednesday. While the alpine and tree line will see continued wind slab formation throughout the forecast period.

    The first wave of this storm system is expected to come in warm. Wet loose is added as a problem for Tuesday-Wednesday. Look out for rain falling on last weekend's snow. Especially in areas which have not seen major warming yet.
