Chinese authorities have ramped up relief efforts that have been slowed by the rugged terrain and high altitude of the disaster area, with relief vehicles bringing food, tents, blankets and other aid.
Efforts were also shifting towards rebuilding to help the tens of thousands left homeless in the mountainous area.
But relief efforts could be hindered as light snow began fell on Tuesday in the region, with more snow and sleet forecast for the next three days.
Temperatures are expected to drop below freezing, Xinhua cited Tsering Tashi, the deputy chief of the Yushu Prefecture Meteorological Bureau, as saying.
Light snow fell in some areas of the quake zone on Tuesday as rescuers continued efforts to try to find survivors trapped under rubble.
The strong response to the quake by the Chinese government has not been without political overtones in the sensitive Tibetan region.
Jia Qinglin, China’s most senior parliamentary adviser and the Communist party’s No 4 ranking leader, warned at a meeting on Monday of “hostile forces from abroad working to cause disruptions and sabotage” to the disaster-relief effort, CCTV said.
Jia did not mention any specific individuals, but the Chinese government often refers to supporters of the Dalai Lama and advocates of Tibetan independence as “hostile forces”.
