Today's storm won't change the avalanche conditions much. You're main concern remains in the higher elevation more northerly facing terrain. Weak faceted snow near the ground is the weak layer, last week's storm as well as today's snow forms the slab. This is what is known as a Persistent Weak Layer and the only mitigation that is 100% effective is avoidance. You simply need to avoid this type of steep terrain until the weak layer has stabilized.
Remember, you can safely travel in this terrain as long as you stick to slopes that are 30˚ or less in steepness and make sure there are not steep slopes above you.
