In the past a few days:
Mt. Wu Dong - snowy and frosty. Significant disaster for spring high mountain Dan Cong :-(
Northern Zhejiang - a lot of snow (a lot for Zhejiang, not comparable to New England winter snow though). An Ji Bai Cha, Zhejiang Long Jing (including Da Fo Long Jing) and some other green teas' growth is temporarily set back. Production may decrease. As long as it becomes warm and normal spring weather, tea quality will not be largely affected.
Hangzhou, Zhejiang - some snow. Production may decrease a bit, but over all quality shouldn't be affected (finger crossed, as long as weather becomes spring-like from now on).
Tie Guan Yin - safe! Although there was some snow in southern Fujian, the tea buds have not come out yet so the tea trees were not affected by the snow.
Ben Shan, Huang Jin Gui and some other early season Se Zhong oolong - suffered a lot.
Overall, the climate fluctuation is not disastrous to most teas but may cause significant loss for Dan Cong farmers.
