Storm Risk Analysis
Old Erowal Bay, New South Wales, has a location-specific storm risk profile. This includes exposure to severe thunderstorms, hail, damaging winds, and — in tropical regions — cyclone impacts. The applicable wind region classification under AS/NZS 1170.2 influences building design standards for Old Erowal Bay.
Severe thunderstorms affecting Old Erowal Bay can produce damaging wind gusts, large hail, and intense rainfall. The Bureau of Meteorology issues severe weather warnings for New South Wales, and historical storm data helps characterise the frequency and intensity of events in the region.
CSIRO research indicates that the intensity of severe convective storms — including those producing hail and damaging winds — may increase in a warming climate. For Old Erowal Bay property owners, this reinforces the value of storm-resistant building features and comprehensive insurance.
