Heavy snow hit the area on Saturday. A weather service official says the mountaineering team might have to postpone their climb.

Officials say they are closely monitoring the weather changes, and awaiting forecast data from the meteorological center.

The Olympic torch relay includes a climb to the top of the 8844-meter Qomolangma, which spans Nepal and the Chinese region of Tibet.
