Storm Risk Analysis
Throssell in Western Australia falls within a wind region classified under AS/NZS 1170.2, the Australian/New Zealand standard for structural design actions for wind. Wind regions range from A (lowest) to D (most severe — tropical cyclone-prone areas), and the applicable wind classification affects building design requirements for new construction in Throssell.
Severe thunderstorms in Throssell can bring damaging wind gusts, large hail, and intense rainfall. The Bureau of Meteorology issues severe weather warnings for Western Australia, and historical storm data shows that properties in Throssell may be exposed to these events depending on local geography and storm track patterns.
CSIRO research indicates that the intensity of severe convective storms — including those producing hail and damaging winds — may increase in a warming climate, though the precise local effects for Throssell depend on regional atmospheric conditions. Property owners should consider storm-resistant building features and adequate insurance.
ClimateNest provides address-level storm risk reports for Throssell properties including wind zone classification, hail risk probability, and property-specific mitigation recommendations based on your building characteristics.
Throssell sits within ClimateNest's suburb-level hazard model for severe storm risk. 7.2% of the suburb's land area is mapped in high-risk severe storm zones and 66.3% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Throssell.
Throssell (postcode 6401) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (12.3% of land in high-risk zones), riverine flood (9.5% of land in high-risk zones), tropical cyclone (7.2% of land in high-risk zones). Exposure is not uniform across Throssell — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

What storm mitigation measures should Throssell property owners consider?
Storm mitigation includes impact-resistant roofing materials, cyclone-rated fixings where required, window and door shutters, regular roof and gutter maintenance, securing outdoor items, and checking that your property complies with current wind load standards under the National Construction Code.
