Learn moreAbout Katherine South's Climate Risk Profile
Katherine South, located in the Northern Territory, is subject to a range of climate-related risks. The primary concerns are flooding due to its proximity to the Katherine River, and extreme heat during the summer months. Bushfire risk is also a factor, particularly during the dry season.
Flooding events can occur due to intense rainfall, leading to riverine and flash flooding. Climate change is projected to increase the intensity of rainfall events, potentially increasing the frequency and severity of flooding in the region. The Katherine River's behavior is a key factor in understanding flood risk.
Extreme heat is another significant concern, with Katherine South experiencing high temperatures and heatwaves. These conditions can pose health risks, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. Climate change is expected to further increase average temperatures and the frequency of heatwaves.
Bushfire risk is present due to the surrounding grasslands and bushland. Dry conditions and high temperatures during the dry season can create conditions conducive to bushfires. While not as prominent as flood and heat risk, it remains a factor to consider.
Coastal risks are minimal due to Katherine South's inland location. Sea level rise and coastal erosion are not direct threats to the suburb.
