Winds gusting up to 115mph leave pedestrians struggling to stand in Oregon

Hurricane-strength winds batter The Crown Point observatory near Corbett, Oregon where passers-by struggle to remain upright in the gales.

Footage shows three people being knocked down on the road by the strength of the wind, while a car door was flipped backwards off its hinge as a driver was getting in.

Steve Pierce from the American Meteorological Society registered an unofficial gust of 115mph on Monday.
