Sichuan Tour

Expect to arrive at Jiuzhaigou National Park on 6.11.13 . Our tour destinations are Chengdu, Maoxian, JZG, Dujiangyang, Leshan, Emeishan and return to Chengdu. Our tour will be by using tour bus and my questions are:-
1. Due to the recent rainstom at Sichuan what are the roads conditions/accessibility at all those places mentioned above, especially JZG National Park?
2. What is the temperature/weather during that period at JZG National Park ?
3. I understand (correct me if i am wrong) that it is early winter during the month of November. Can we see snow, especially on the mountain peaks?
Thanks.
