Climate Hazard Breakdown for Gregory Hills

Flood

Gregory Hills faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. Development and urbanization can increase runoff, exacerbating flood risk.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

Gregory Hills has a moderate bushfire risk due to its proximity to bushland areas. Hot, dry conditions during the bushfire season can increase the likelihood of fire ignition and spread.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Gregory Hills is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

Key drivers:

  • ·Rising global temperatures
  • ·Urban heat island effect

Coastal

Gregory Hills is not directly exposed to coastal risks such as sea level rise and coastal erosion due to its inland location.

How the region's climate is projected to change

Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.

Temperature

+0.5 to 1.1°C by 2030

Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.

Rainfall

Winter rain down up to 15% by 2030

The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.

Fire weather

Harsher, magnitude uncertain

High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.

Sea level

+0.12 m by 2030

At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

About Gregory Hills's Climate Risk Profile

Gregory Hills, located in the southwestern suburbs of Sydney, is susceptible to several climate-related risks. The primary concerns are flooding due to increased rainfall intensity and potential overflows from local waterways, and heatwaves, which are projected to become more frequent and intense. The suburb also faces a moderate risk of bushfires due to its proximity to bushland areas.

Flooding can occur due to heavy rainfall events, particularly during the summer months. Urban development in the area can increase runoff, potentially overwhelming drainage systems and leading to flash flooding. Residents should be aware of flood warnings and have a plan in place to protect their property and ensure their safety.

Heatwaves are another significant concern for Gregory Hills. As global temperatures rise, the suburb is likely to experience more frequent and prolonged periods of extreme heat. This can pose a health risk, especially for vulnerable populations such as the elderly, children, and those with pre-existing medical conditions. It is important to stay hydrated, seek air-conditioned environments, and check on neighbors during heatwaves.

While the risk of bushfires is moderate, it should not be ignored. Gregory Hills is located near bushland areas, which can become dry and highly flammable during the bushfire season. Residents should maintain their properties to reduce fire hazards and be prepared to evacuate if necessary.

Overall, Gregory Hills needs to focus on adaptation strategies to mitigate the impacts of climate change. This includes improving drainage infrastructure to reduce flood risk, implementing heatwave management plans, and promoting bushfire safety awareness.
