Helsport tent in a piteraq wind above 35m/s

Durring our 44 days ski expedition across Greenland from South Greenland (Narsarsuaq) to East Greenland (Isortoq) we was hit by several Piteraq winds.
If you translate the greenlandic word Piteraq it means "something that attacks you". We also got that feeling :) We ended up spending 9 full days with storm in our Helsport tent.
