 Only about 10 of the 40 accommodation huts were left standing.Some of the huts were removed from their concrete foundations, and were carried by the winds and smashed into other buildings.Showing how strong Rosita's winds were, a sea container weighing 2.5 tonnes (5500 lb) and filled with 2 to 3 tonnes (4400 to 6600 lb) of equipment was blown 700 m (0.4 mile) across sand dunes.
