I made the trail last weekend and you can find pictures at
Mt Whitney trail You will need snowshoes until Trail Crest and then I highly recommend crampons from Trail Crest to the top because the snow was icy.
There were several feet of snow and after the recent storm you will likely have no tracks anymore. The switchbacks are impassable, so you need to go straight up. Be careful for avalanches after the recent storm, it may take a few days for the snow to settle.
