Large severe floods within the Municipality generally occur as a result of a moist warm airflow from northern Australia bringing moderate to heavy rainfall over a period of 12 hours or more following a prolonged period of general rainfall.
Short duration, high intensity rainfall (usually associated with thunderstorms) can also cause localised flooding within the municipality along overland flow paths when the local urban drainage system surcharges. Flooding from these storms occur with little warning and localised damage can be severe.
A Flood and Storm Emergency Plan has been prepared in collaboration with the State Emergency Service, Municipal Emergency Management Planning Committee and Council. To view the plan visit the State Emergency Service website.
Being prepared for flood and storms reduces the impact of the event and assists you in recovering from a flood. To assist you in your planning, view this State Emergency Service short video here.
There is a history of floods in the Seaholme and Altona areas of Hobsons Bay. To ensure you are ready for a flood or storm, local flood guides have been developed by the State Emergency Service. View these guides or find out more.
