I drove the Transfagarasan from the Northern side yesterday. It is indeed closed at Balea Lake. There is 2 meter deep snow across the entire road starting about 150 meters from the tunnel.
We were told there is no access past the lodge at Balea Lake (Cabana Paltinu) for either motorcycles or cars (at least the cars part was obvious).
Today I drove up the Transfagarasan from the South side. I only went as far as the dam at the South end of Lake Vidaru and then turned back. The roads were clear and fine all the way up to the dam, so I can't say if/where the blockage is past there.
My friends were convinced (despite my insistence otherwise) that the Transalpina was closed off, so they refused to let me drag them with me to drive it. Oh well, I'll save that for another trip.
Here's a quick shot I snapped on the way back down yesterday, about 1.5km below Balea Lake:
