One survivor, Glen Plake, was quoted as saying that "there were 25 tents at Camp 3 and all of them were destroyed; 12 tents at Camp 2 were banged up and moved around".
Mr Plake said he had lost a few front teeth and had an eye injury after being swept 300 metres down the mountain,
according to Trey Cook, the editor-in-chief of EpicTV.com, which makes adventure sports films.
Deteriorating weather conditions meant it was impossible to continue air searches of the mountain on Sunday.
The climbers were caught at around 7,000 metres (22,960ft) as they were preparing to head toward the summit, which is 8,156m high.
