A temporally compounding event occurs when a series of hazards affects the same region, exacerbating the impact of any of the individual events. For example, the impact of a series of tropical cyclones in quick succession could impact a region far more than if there was more time between the cyclones. An Australian example is when, in June 2007, coastal New South Wales was hit by five East Coast Lows in close succession, causing flooding and damage. The impact of each individual storm was exacerbated where the different storms affected regions that were still in the process of recovering from the previous storm and put stress on emergency services, which had little time to recover between events.
