Learn moreAbout Morawa's Climate Risk Profile
Morawa, located in the Mid West region of Western Australia, is increasingly vulnerable to the impacts of climate change. The primary concerns are rising temperatures, increased bushfire risk, and potential for more intense flooding events. While the suburb's inland location protects it from direct coastal threats, the broader effects of climate change will still be felt.
The risk of bushfires is a significant concern for Morawa. The surrounding landscape, characterized by dry vegetation, becomes highly flammable during the summer months. Higher temperatures and prolonged dry spells exacerbate this risk, making the region more susceptible to devastating bushfires. Residents need to be vigilant and prepared for potential evacuations.
Heatwaves are also becoming more frequent and intense in Morawa. The already hot summers are expected to become even hotter, posing a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions. Access to cooling and adequate hydration will be crucial during these events.
Flooding is another area of concern, with potential for increased rainfall intensity leading to flash flooding and riverine flooding along the Morawa River. Improved drainage infrastructure and flood management strategies are needed to mitigate these risks. While coastal risks are minimal, the interconnectedness of climate systems means that changes in sea levels and ocean currents can still indirectly affect the region.
