Last year in May, a waterspout appeared off the coast of New South Wales, Australia. Spiralling up into a bank of clouds, the natural wonder reached heights of up to 600 metres. Waterspouts are formed when high layers of cold air blow across water while warm air sweeps up from below. Various sea life is often caught up in the funnel, and then dumped many miles away on land. In these days, Sydney and the surrounding areas have suffered storms, heavy rain and flooding, causing crashes and road closures in the city centre.
