Comment: Broome residents and business owners say wind and rain have exceeded the category two Cyclone Hilda and category one Cyclone Joyce which both hit the Kimberley coast in the past month. As well as record rainfall the tropical low brought winds of 100 kilometres per hour - with gusts of up to 125kph. According to the Bureau of Meteorology, the tourist town was hit with more than double its average January rainfall in a 22-hour period.
