Climate Hazard Breakdown for Frenchs Forest

Flood

Frenchs Forest faces a moderate risk of flooding due to its proximity to waterways and increasing rainfall intensity. Local creeks and drainage systems can be overwhelmed during heavy downpours.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

Frenchs Forest has a high bushfire risk due to its location near significant bushland areas. Dry conditions and strong winds can exacerbate the risk during bushfire season.

Key drivers:

  • ·Dry climate
  • ·Proximity to bushland

Heat

Frenchs Forest experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

Frenchs Forest has a low coastal risk due to its distance from the immediate coastline. Sea level rise and coastal erosion are not significant concerns for this suburb.

Key drivers:

  • ·Distance from the coast

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 Frenchs Forest's Climate Risk Profile

Frenchs Forest, located on the Northern Beaches of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, while increasing rainfall intensity contributes to flooding concerns.

Climate projections indicate a rise in average temperatures and more frequent heatwaves, posing health risks to vulnerable populations. Changes in rainfall patterns are expected to increase the frequency and intensity of flooding events, potentially impacting property and infrastructure.

The local council is implementing strategies to mitigate these risks, including improved drainage systems and bushfire management plans. However, individual preparedness and community resilience are crucial for adapting to the changing climate.

Residents are encouraged to stay informed about local weather conditions, develop emergency plans, and take steps to protect their properties. Collaboration between residents, local government, and emergency services is essential for building a climate-resilient community.
