Matthew, this storm will not bring enough snow to create any avalanche situations, so I wouldn't worry about that this time. Avalanche danger increases when there is a heavy storm dumping a lot of new snow on top of a solid base of existing snow.
More importantly will be the depth of snow snow and how much it impedes your ability to walk up the trail. Breaking trail in snow is very tiring.
People can see from timb's post how tough the going can be. Their trouble with postholing up to the waist is due to their trying to go up the slope (some call it a chute) west of the switchbacks. The rocks and boulders in that area are big and blocky, and trying to go up that on a thin layer of new snow is a lot of trouble, since you can't see what lies beneath the snow: it might be a solid boulder, or it might be the space between boulders with a big hole. People should try to stay on the trail all the way up until the snow really solidifies, and it takes a few storms before that happens.
A note about the snow blindness: It is sunburn in the eyes! Do NOT hike in snow without sunglasses!!! Even without direct sunlight, you can get a burn.
