About Wonnangatta's Climate Risk Profile

Wonnangatta, located in the Victorian Alps, is a remote and rugged area known for its natural beauty and challenging terrain. The region is highly vulnerable to climate change impacts, particularly bushfires and flooding.

The risk of bushfires is a major concern for Wonnangatta. The area is surrounded by dense forests and grasslands, which can become highly flammable during hot, dry periods. Climate change is projected to increase the frequency and severity of bushfire weather, posing a significant threat to lives, property, and the environment.

Flooding is another significant risk for Wonnangatta. The area is located near several rivers and streams, which can overflow during periods of heavy rainfall. Climate change is expected to increase the intensity of rainfall events, leading to more frequent and severe flooding.

Rising temperatures are also a concern for Wonnangatta. The area is already experiencing warmer summers, and climate change is projected to increase average temperatures further. This could lead to heat stress for vulnerable populations and increased demand for water resources.

Overall, Wonnangatta faces a range of climate change risks that require careful planning and adaptation measures. Residents and businesses should take steps to prepare for more frequent and intense extreme weather events.
