East Coast Low Quiz – Australia's Coastal Storms

East coast lows are intense low-pressure systems that form off the coast of eastern Australia, especially New South Wales and southeast Queensland. They are most common in autumn and winter.

Fueled by warm Tasman Sea waters, some deepen rapidly into so-called bomb lows. They bring heavy rain, damaging winds and large seas, causing flooding and coastal erosion.

In 2007 an east coast low drove the coal ship Pasha Bulker onto Nobbys Beach in Newcastle, and in 2016 waves damaged homes at Collaroy in Sydney. The Bureau of Meteorology issues warnings when these systems develop.
