Tangjiashan - here we go...

Xinhua has reported in the last 20 minutes that:
"Water level of China's main quake lake Tangjiashan climbed to the critical point of 740 meters on a sluice channel at 0:00 a.m. Saturday, but the long-awaited drainage hasn't started yet."

Given that we know that it has been raining in the area this afternoon, over-topping must be about to start. Hold onto your hats...!

And can I just say good luck to everyone in the path. I hope to wake up tomorrow to hear that this hasn't even made the news. If so, the Chinese authorities will have achieved the almost impossible.
